How to Configure the Virtual Network Editor in VMware Workstation

If a virtual machine can’t reach the network, the problem often isn’t inside the VM. The real issue hides in the host’s network layer. Virtual Network Editor steps in right at this point. In short, it is the virtual network brain of VMware Workstation.

In this guide, we put that brain on the table. First, we will start with VMnet types. Then, we will move on to the vnetlib64.exe command line. Finally, we will also cover Registry repair, Linux configuration, and VLAN limits.

So why is this topic so critical? This is because when one vmnet setting breaks, a single VM is not the only one affected. Also, every virtual machine on the host is affected at the same time. Therefore, this tool controls the unseen architecture of your network.

Network management brings routers, switches, and firewalls to mind. Yet the virtualization layer needs a similar discipline. We manage virtual switches, DHCP scopes, and NAT rules from this panel. On top of that, network monitoring and troubleshooting start here too.

The 2025 and 2026 releases brought major changes. For example, 26H1 is now fully 64-bit. Also, the free license model became permanent. At the same time, new problems emerged in 26H1. For instance, the wrong adapter can be selected after a network reset. We will cover all of this with current sources.

What Is Virtual Network Editor and What Does It Do?

This tool manages the virtual network topology of your host. It ships with the core structure of VMware Workstation. Also, it builds the bridge between your physical network and virtual machines. On top of that, it lets you create your own isolated networks. In short, it is the router and controller of virtual network traffic.

So what does this tool control? First, it manages VMnet adapters. These adapters act as a virtual switch (vSwitch). Therefore, each one represents a different broadcast domain.

In addition, you edit the DHCP scope, NAT gateway address, and DNS proxy settings. That way, you shape your whole virtual network from one panel.

Its most critical feature is that it acts across the whole host. That means any change you make here affects every VM. So you must always shut down the VMs before you change a setting.

Otherwise, you can seriously disrupt the bridged network. Evidence from the field: teams that ignored this warning faced outages that lasted hours.

When you install VMware Workstation, the system also installs the virtual network adapter configuration program. It adds three virtual network adapters to the Network Connections window. These adapters are named Network Adapter VMnet.

Core Functions of Virtual Network Editor and Its Host-Wide Impact

The core functions are much broader than they look. First comes virtual switch management. You edit standard switches such as VMnet0, VMnet1, and VMnet8. Also, you add custom switches from VMnet2 through VMnet7. That way, each one forms an independent layer-2 segment.

The second function is address management. You set the start and end IPs of the DHCP server. On top of that, you set the lease time. Besides that, you define static IP reservations. As a result, your virtual machines are placed in the right network segment.

The third function is routing and NAT management. You change the gateway IP. Then, you add port forwarding rules. Also, you configure the DNS proxy. Therefore, you control the path your VMs take when they reach the internet.

The fourth and most overlooked function is host virtual adapter control. For VMnet1 and VMnet8, the system creates virtual network adapters on the host side. These adapters let the host join the virtual networks.

If these adapters vanish, the link between the VM and the host breaks. On top of that, network monitoring tools watch traffic through these adapters too.

Which Releases Have It? Virtual Network Editor Status in Workstation Pro, Player, and Fusion

The release question is where users are most often confused. This tool comes built in with every modern Workstation Pro release. For example, you reach it from the Edit menu in the 17.x series and in 25H2 and 26H1. That means Pro users need no extra install.

Now let’s turn to Workstation Player. Broadcom ended the Player product in 2024. In fact, the 17.x branch of Player fully retired in November 2025. Therefore, if you still use Player today, you do not have the virtual network tool interface. On top of that, official support has ended.

So what is the fix? In short, the fix is to move to Workstation Pro. This is because Broadcom made Workstation Pro free as of November 11, 2024. A license key is no longer needed.

In 17.5.2 and later releases, you can check the personal use option and continue. This is the cleanest way to escape the network limits in Player.

Other Platforms and General Comparison Table

On the Fusion side, the story is different. On macOS, Fusion Pro has its own virtual network editor. However, the interface names and menu paths differ from those in Windows.

For example, Fusion groups network management mostly under “Network Preferences”. Still, the core logic is the same: VMnet adapters, DHCP scope, and NAT rules.

To sum up: the Pro release is the only official way to reach the full power of this tool. Sticking with Player no longer makes sense. On top of that, the free Pro offering removes this debate completely.

How to Open Virtual Network Editor? Windows, Linux, and Admin Rights

The way you open it depends on the OS. On Windows, you reach it from the menu. On Linux, the command line takes over. In both cases, permission is a critical requirement. When you open it with the wrong rights, the Change Settings button stays gray.

In this section, we will go step by step for both platforms. Also, we will solve the most common “gray button” issue. This issue is the first obstacle that 70% of users encounter. Luckily, the fix is simpler than it looks.

Opening Virtual Network Tool on Windows and the Administrator Requirement

On Windows, there are two different paths. The first path is to use the Workstation Pro interface. Follow these steps:

1. Open VMware Workstation Pro.
2. Click the Edit option in the top menu.
3. Select Virtual Network Editor from the list that opens.
4. A VMnet list appears.

The second path is to use the executable file directly. First, go to the install folder. The default location is C:\Program Files (x86)\VMware\VMware Workstation\. Then, you will find the vmnetcfg.exe file there. Note that this file opens with full rights only as an administrator.

Right-click the file and select Run as administrator. When the UAC prompt appears, select Yes. That makes the Change Settings button active. Otherwise, you stay in view-only mode. As a result, this is the most common mistake and it costs hours.

Opening with the vmware-netcfg Command and Root Password on Linux

The process is somewhat more technical on Linux. You can also open it from the GUI. However, the most reliable path is the command line. First, open a terminal and enter this command:

sudo vmware-netcfg

This command asks for the root password. After you enter the password, the virtual network configuration tool window opens. If the system cannot find the vmware-netcfg command, you must use the full path:

sudo /usr/lib/vmware/bin/vmware-netcfg

On some distros, this path also appears as /usr/bin/vmware-netcfg. To find the full path of the command, run which vmware-netcfg. Also, you can see the current options with vmware-netcfg --help.

You cannot change anything in this tool without the root password. This is because network configuration on Linux is a privileged task. Even when you open it with sudo, some distros may ask for extra rights.

In this case, switch to a root session with sudo -i. Then, try the command again. In other words, you cannot skip the permission layer.

Change Settings Is Gray and Won’t Click: Service and Permission Fix

This issue is a common nightmare for users. The button is gray; when you click it, nothing happens. Do not panic. The cause is almost always a lack of rights. To fix it, apply these steps in order:

1. Run as administrator: right-click the vmnetcfg.exe file. Then select “Run as administrator”.
2. Give UAC approval: press the “Yes” button in the security prompt.
3. Check services: open services.msc. See if VMware Authorization Service is running.
4. Check the VMnetDHCP and VMnetNAT services. If they have stopped, start them.
5. Try again: close the tool. Open it again as administrator.

If it still stays gray, that means VMware services are not working correctly. In this case, a reboot is the cleanest fix. This is because some drivers lock during load. Also, a reboot clears these locks.

VMware Workstation Virtual Network Types: VMnet0, VMnet1, VMnet8, and Custom VMnet Networks

VMware’s network architecture rests on three main pillars: Bridged, Host-Only, and NAT. These three modes serve different use cases. Also, each one has its own VMnet adapter. For example, VMnet0 is for bridging, VMnet1 is for an isolated network, and VMnet8 is set aside for NAT.

However, the job does not end there. When you need them, you can create custom networks from VMnet2 through VMnet7. That way, you run more than one isolated segment on a single host. Let’s look at these structures one by one. This section clarifies what each one does.

For guidance, note that when you create a new virtual machine with VMware, the system sets the network to NAT on its own. Now let’s review the current network configuration options step by step.

VMnet0 Bridged: Direct Join to the Physical Network and Editor Settings

Bridged mode links your virtual machine straight to your physical network. The VM sits in the same layer-2 broadcast domain as your host. That means other devices on the network see it as a real computer. It answers ARP requests and replies to ICMP packets. This mode is ideal for network tests and server simulations.

For example, if you use the 192.168.1.0/24 address range, set the virtual machine to Bridged. That way, the virtual machine gets an IP address from the DHCP server on its own. As a result, this method gives the fastest result in lab setups.

When you select VMnet0 in Virtual Editor, you see the “Bridge to” menu. By default, “Automatic” is selected. This means VMware bridges to all physical adapters on its own.

However, this behavior can cause trouble in multi-NIC setups. For example, when a VPN adapter comes up, the VM can pick the wrong card.

In the 26H1 release, this problem became more visible. When a network adapter resets, VMware can pick the wrong card. So picking a specific card manually is safer.

Select your Ethernet or Wi-Fi adapter from the drop-down menu. If you have more than one physical card, you see each one separately. After you make your choice, press OK. That way, the change affects all bridged VMs.

The image below shows the physical network adapters that the virtual network editor sees.

VMnet1 Host-Only: Isolated Network, DHCP, and Host Virtual Adapter

Host-Only mode creates a fully isolated network. Virtual machines talk to each other and to the host. However, they cannot reach the outside world. This mode is vital for security tests and isolated labs. In short, VMnet1 is the default adapter for this mode.

For example, you use the GNS3 network simulator when you prepare for Cisco exams. To understand Cisco routers better, split the machines into different networks. For this, you use the Host-Only network configuration.

When you select VMnet1 in the editor, you see three basic settings. These are Subnet IP, Subnet Mask, and DHCP Settings. Subnet IP sets the address block of your virtual network. For example, if you enter 192.168.100.0, VMs get an IP from this range. The mask is usually 255.255.255.0, or /24 CIDR notation.

In the DHCP settings, you change the start and end IPs. Also, you set the lease time. On top of that, the Host virtual adapter option controls whether the host joins this network.

If you remove this adapter, the link between the host and the VMs breaks. So keep the ‘Connect a host virtual adapter to this network’ box checked.

A Host-Only network has no internet access. This is not a limit but a deliberate design choice. Isolation gives you a safe space for malware analysis or penetration testing.

Also, broadcast traffic does not leak out. That means your virtual lab becomes a fully closed box. On top of that, ARP and ICMP traffic stays only in this segment.

VMnet8 NAT: Internet Access, Gateway, and NAT Settings in the Editor

NAT mode is the most common connection type. The virtual machine reaches the internet. However, no one can reach it directly from outside. This is because the host acts as a broker for the VM. In short, VMnet8 is the standard adapter for this mode.

When you configure VMnet8 as NAT, also select VMnet8 inside the VM. As a result, the virtual machine reaches the internet through VMnet8. In fact, this structure is standard in corporate test environments.

When you select VMnet8 in the editor, the NAT Settings button becomes active. When you click it, you see the gateway IP and DNS proxy settings. The gateway is usually the first usable address in the subnet.

For example, if the subnet is 192.168.50.0, the gateway can be 192.168.50.2. That way, NAT routes outbound traffic through this address.

For port configuration, first select the VMnet. Then click the NAT Settings button.

In the NAT Settings window, you can configure port forwarding. You map one host port to one VM port.

For example, forward host port 8080 to VM port 80. That way, requests from outside reach the VM web server. Also, you define separate rules for TCP and UDP.

If you want to define a different IP block, click the DHCP Settings button. Then change the address in the Starting IP Address and Ending IP Address fields.

DNS proxy is a key part of NAT mode. VMs do not send DNS queries directly out. The host proxies these queries. This way, you manage DNS configuration from one place.

If you encounter DNS issues, turn the “Auto detect available DNS servers” option off and on. In release 17.5.2, this method fixed internet access problems.

VMnet2–VMnet7 Custom Networks: Adding and Removing New Virtual Switches

The standard three adapters do not meet every need. If you build multi-tier test environments, you need extra segments. At this point, the custom VMnet range comes in. In short, you can create six custom switches from VMnet2 through VMnet7.

At this point, consider what creating a custom VMnet network adds. Each new network brings its own DHCP scope and broadcast domain. You must shut down the VMs before you build this structure.

Follow these steps to add a new virtual switch:

1. Open Virtual Network Editor as administrator.
2. Click the Add Network button.
3. Select a VMnet number from the drop-down list. For example, VMnet2.
4. Press the OK button.
5. The new adapter appears in the list.

Then you set the type of this new adapter. Check one of the Bridged, Host-Only, or NAT options. For example, select VMnet2 for a second Host-Only network. Then check the “Host-only” radio button.

Also, you define the subnet settings yourself. That way, you create more than one host-only network. On top of that, each one has its own DHCP scope and broadcast domain.

To delete one, select the VMnet and press the Remove Network button. But note: if a VM uses that network at that moment, its link breaks. So shut down all VMs before you delete.

Also, the DHCP and NAT configuration of the network you delete is removed. If you recreate it, you must set the options from scratch.

If you often use custom VMnet networks, LAN segment configuration makes your job easier. In fact, each segment creates its own broadcast domain. If you remove a VM from the wrong segment, its link drops at once. You must plan this split from the start.

Which Network Type Should I Pick? Decision Table

The network type choice depends on your project needs. The table below helps you decide quickly. In short, match these rows to your needs.

Ask this question when you decide: will the VM talk to the outside world? If the answer is yes, pick NAT or Bridged. If the answer is no, Host-Only is enough. Next, should the VM look like a real device on the network? If it must, Bridged is the choice; if not, NAT is ideal.

The Unseen Engine of VMware Network Editor: vnetlib.exe and vnetlib64.exe

The GUI is only the visible tip of the iceberg. So, the real power sits in the command line. vnetlib.exe and vnetlib64.exe on 64-bit systems manage all virtual network configuration. With this tool, you take backups, restore them, and repair broken drivers.

In this section, we will review three critical command sets. First, configuration backup with export/import. Then, subnet and DHCP changes with set commands. Finally, driver repair with install/reinstall. Once you learn these commands, you control your network even when the GUI will not open.

Configuration Backup with vnetlib64.exe — export and — import

A configuration backup is every sysadmin’s first rule. You export your VMware Network settings to one file. Then you restore them when needed.

First, open an admin command prompt. Then go to the install folder:

cd "C:\\Program Files (x86)\\VMware\\VMware Workstation"

Use this syntax for the export command:

vnetlib64.exe -- export "D:\\yedek\\vn_backup.txt"

This command writes all VMnet configuration to the file you name. The file size is usually a few kilobytes. Also, it holds subnet settings, DHCP scopes, and NAT rules.

To restore, run the same command with the import key:

vnetlib64.exe -- import "D:\\yedek\\vn_backup.txt"

The import operation overwrites the current configuration. So back up the current state first. Also, all VMs must be off during import.

Otherwise, an inconsistent state can occur. At the same time, this method is ideal for moving settings to another computer. In short, a configuration backup is the base of your disaster recovery plan.

Changing Subnet, DHCP, and NAT Settings from the Command Line with vnetlib — set

Sometimes you cannot reach the GUI. Maybe the screen resolution does not fit. Maybe you write an automation script. In this case, -- set commands can help.

First, list the current configuration:

vnetlib64.exe -- list

This command shows all VMnets and their basic properties. Then change the subnet IP of a specific VMnet. Example:

vnetlib64.exe -- set vnet vmnet8 subnet 192.168.200.0

To set the DHCP start and end addresses:

vnetlib64.exe -- set vnet vmnet8 dhcp start 192.168.200.100\nvnetlib64.exe -- set vnet vmnet8 dhcp end 192.168.200.200

To change the NAT gateway address:

vnetlib64.exe -- set vnet vmnet8 nat gateway 192.168.200.2

After each command, restart the services to apply the change. For example, net stop VMnetDHCP && net start VMnetDHCP does this. Also, run the -- list command again to verify the changes.

vnetlib — install / — uninstall / — reinstall: Repairing Broken Virtual Network Drivers

Sometimes virtual network adapters go missing. For example, VMnet1 vanishes. VMnet8 turns into an unidentified network. In this case, reload the drivers. vnetlib64.exe offers three keys for this job.

The install command loads missing drivers:

vnetlib64.exe -- install

The uninstall command removes current virtual network drivers:

vnetlib64.exe -- uninstall

Reinstall first removes, then reloads:

vnetlib64.exe -- reinstall

Reinstall is the most common repair method. This is because it does a clean install in one step. However, all VMs must be off during the process. Also, admin rights are required. After the process ends, reboot the computer.

If the problem continues after reinstall, check the vmnetbridge service. Also, this service is critical for bridging. Stop and restart it from the Services panel. The problem usually clears at this step.

Virtual Network Repair at the Windows Registry and Service Level

Some problems do not yield to the GUI or the command line. The root cause hides in configuration stored in the Windows Registry.

The system keeps VMnet subnet data, DHCP scope, and NAT settings in the Registry. Knowing these keys is essential for advanced repair.

Also, service dependencies are critical. If VMnetDHCP and VMware NAT Service do not run, no VM can get an IP. In this section, we will review Registry locations, service dependencies, and the bridge protocol. Apply the steps with care.

Registry Keys That Store VMnet Subnet and DHCP Scope

VMware stores virtual network configuration in the Registry. The main location is:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VMnetDHCP

Under this key, a separate Parameters subkey exists for each VMnet. For example, the DHCP scope for VMnet8 is defined here. To see the values, open Registry Editor as admin. But always back up before a change.

NAT settings sit at this location:

HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\VMnetNAT

The gateway IP and port forwarding rules are stored here. Also, you can use the vmnetnat.conf file. This file is usually under C:\ProgramData\VMware\. Also, editing this file can be safer than the Registry.

Checking and Restarting VMnetDHCP and VMware NAT Service Dependencies

These two services are the lifeline of your virtual network. VMnetDHCP hands out IPs. VMware NAT Service takes on internet routing. Therefore, when either one stops, VMs cannot reach the network.

To check service status:

1. Run the services.msc command.
2. Find the VMnetDHCP service in the list.
3. If its status is not “Running”, right-click it. Select Start.
4. Repeat the same step for VMware NAT Service.

If a service will not start, check its dependencies. VMnetDHCP depends on AFD and TCP/IP protocols. VMware NAT Service depends on VMnetDHCP. If one of these dependencies is missing, the service will not start.

To restart from the command line:

net stop VMnetDHCP && net start VMnetDHCP\nnet stop "VMware NAT Service" && net start "VMware NAT Service"

Run these commands in an admin command prompt. After the services start, reboot your VM. Then check whether it got an IP. If there is still no IP, check the DHCP scope and the VMnet adapter link.

vmnetbridge and VMware Bridge Protocol: Why Does Bridging Fail?

If your VM cannot get an IP in Bridged mode, the problem is usually in the bridge layer. VMware Bridge Protocol makes the link between the physical adapter and the virtual switch. If this protocol is off or vmnetbridge has stopped, bridging fails.

First, go to the properties of the physical adapter. In the Network Connections window (ncpa.cpl), right-click your adapter. Select Properties. Check whether VMware Bridge Protocol is checked in the list. If not, check it and press OK.

Then check the vmnetbridge service. It appears in the Services panel under the name VMware Bridge Protocol. Its status should be “Running”. If it stopped, start it. If the service is missing, repair the VMware install.

Another common cause is the priority order of the physical adapter. Windows sets the connection order through Advanced Settings.

If Automatic is selected in Virtual Network tool, VMware follows this order. If the VPN adapter is at the top of the list, the VM bridges to the wrong card. So manual selection is always safer.

VMware Network Editor on Linux: vmware-netcfg, vmware-networks, and /etc/vmware/networking

Network management on Linux involves more files and services than on Windows. On top of that, vmware-netcfg provides a GUI. The vmware-networks service runs in the background. Configuration sits in the /etc/vmware/networking file. Understanding this trio is needed to run a virtual network on Linux.

In this section, you will learn to change subnet and DHCP settings from the command line. Also, we will edit the config file by hand and reload the service. Finally, we will cover promiscuous mode permissions and udev persistence.

Changing Subnet IP and DHCP Settings on Linux with vmware-netcfg

The vmware-netcfg command is the virtual network editor on Linux. First, run it from a terminal with root rights:

sudo vmware-netcfg

In the window that opens, you see the VMnet list. Then select the adapter you want to change. For example, select VMnet8. The Subnet IP field appears at the bottom. Enter your new network address here. For example, 192.168.150.0. The subnet mask becomes 255.255.255.0 on its own.

For DHCP settings, click the DHCP Settings button. Change the start IP and end IP. Also set the lease time. After you save the changes, restart the services:

sudo systemctl restart vmware-networks

If the system does not support systemctl, restart the service the old way:

sudo /etc/init.d/vmware-networks restart

Use the ip addr show vmnet8 command to verify the change. That way, confirm the new IP range appears. Also, check the overall status with vmware-netcfg --status.

Editing the /etc/vmware/networking File and Reloading with vmware-networks

In some cases, you cannot reach the GUI at all. For example, a server has no X11. Then you edit configuration directly in the file. On Linux, virtual network settings are stored in the /etc/vmware/networking file.

First, back up the file before you open it:

sudo cp /etc/vmware/networking /etc/vmware/networking.bak

Then open it with a text editor:

sudo nano /etc/vmware/networking

You see one block for each VMnet in the file. For example, VMnet8 has subnet, mask, and dhcp lines. Change the values. For example:

vmnet8.subnet = 192.168.150.0\nvmnet8.mask = 255.255.255.0\nvmnet8.dhcp.start = 192.168.150.128\nvmnet8.dhcp.end = 192.168.150.254

Save the file and exit. Then reload the service:

sudo vmware-networks --stop\nsudo vmware-networks --start

These commands read the configuration again and bring the virtual networks up. If you get an error, review the logs under /var/log/vmware/. In particular, vmnetbridge.log and vmnetdhcp.log give clues.

Permissions for /dev/vmnet0 and udev Persistence for Promiscuous Mode on Linux

Promiscuous mode lets your virtual machine see all packets. You need it for packet capture and security analysis. However, this mode is off by default on Linux. To turn it on, give access rights to the /dev/vmnet0 device.

First, check the current permissions:

ls -l /dev/vmnet*

Permissions for vmnet0 are usually crw-------. That means only root can access it. If you want the VM to run in promiscuous mode, widen this permission:

sudo chmod 666 /dev/vmnet0

However, this permission disappears on reboot. To make it permanent, write a udev rule:

sudo nano /etc/udev/rules.d/99-vmware-promisc.rules

Add this line to the file:

KERNEL=="vmnet0", MODE="0666"

Save and exit. Then reload the udev rules:

sudo udevadm control --reload-rules\nsudo udevadm trigger

After this step, /dev/vmnet0 appears with 666 rights on every boot. That way, your VM captures packets in promiscuous mode.

Security warning: this permission lets other users watch network traffic. Use it with care on shared systems.

Virtual Network Adapter Types: Choosing vmxnet3, e1000, and e1000e

The VM network adapter type has a direct effect on performance. Moreover, VMware gives you three options: vmxnet3, e1000e, and e1000. Each one is tuned for different cases. A wrong choice causes low throughput or incompatibility.

You can change the network adapter from the VM settings. But shut down the VM for this. After you change the adapter type, the guest OS detects the new hardware. Also, you may need to load a driver.

vmxnet3 vs e1000e vs e1000: Performance and Compatibility Comparison

vmxnet3 is a paravirtualized adapter that VMware built in-house. It offers the highest performance. It gives high throughput with low CPU use. Also, it supports speeds of 10 Gbps and up. Moreover, most modern guest OSes have a built-in driver.

e1000e is an emulated adapter based on Intel 82574. It offers broad compatibility. It runs without trouble, mainly on older OSes. However, its performance trails vmxnet3. On top of that, it can reach a 1 Gbps cap.

e1000 is an even older emulation. It is based on Intel 82545. Almost every OS detects it. Yet it gives the lowest performance. Pick it only when you have no other choice.

MAC Address Management: Automatic, Manual, and Static MAC-IP Mapping

Every virtual adapter has a MAC address. VMware assigns this address on its own. However, some cases need manual input. For example, if you plan to make a DHCP reservation, pin the MAC address.

Automatic assignment is the default. The VM gets the same MAC on every boot. However, when you clone a VM, the program makes a new MAC. That way, you prevent a network clash. If the clones will share the same MAC, set it manually.

To assign a MAC manually, go to the VM settings. Then select the network adapter. Click the Advanced button. Enter the address you want in the MAC Address field. The address must use the 00:50:56:XX:XX:XX format. This range is assigned specifically to VMware. For this reason, do not enter a random address.

For static MAC-IP mapping, use the DHCP configuration. Go to DHCP settings in Network Editor. Create a new reservation with the Add button. Enter the MAC address and the IP you want. That way, the VM gets the same IP on every boot. This method is ideal for server-like VMs.

Subnet, DHCP, and NAT Settings with VMware: IP Planning and Configuration

Subnet planning is the foundation of your virtual network. A poorly chosen subnet leads to clashes and broken links. In this section, you will learn to change the subnet IP, mask, and DHCP scope. Then we will move to NAT gateway and port forwarding settings.

Remember: when you change the subnet of a VMnet, every VM that uses that network is affected. Also, VMs see a link drop until they get a new IP from DHCP. So make these changes in a maintenance window.

Changing VMnet Subnet IP Range and Subnet Mask

Select the VMnet you want to change in Network Editor. For example, VMnet8. You see the Subnet IP field at the bottom. Enter the new network address here. For example, 10.10.10.0. Also, the Subnet Mask field becomes 255.255.255.0 on its own.

If you want a different mask, select it from the drop-down menu. For example, 255.255.0.0, or /16. This means 65,534 usable host addresses. However, a wide broadcast domain can lower performance. On top of that, /24 is ideal for most labs.

Thinking in CIDR notation is easier. /24 = 255.255.255.0. /16 = 255.255.0.0. /25 = 255.255.255.128. Use a subnet calculator to find the usable host count.

For example, /24 has 254 usable hosts. You subtract the network address and broadcast address. Also, VLSM lets you create segments of different sizes.

Press Apply or OK to apply the change. That way, VMware puts the new subnet into service right away. However, VMs may keep their old IPs. Wait until the DHCP lease ends or reboot the VMs.

DHCP Scope, Start-End IP, and Lease Time Settings

In VMware software, the DHCP scope sets the IP range handed out to VMs. Click the DHCP Settings button in Network Editor. Three fields appear: Start IP address, End IP address, and Lease time.

Set the start IP after the first usable address of the subnet. For example, if the subnet is 192.168.50.0, the gateway can be 192.168.50.2.

If you set the DHCP start to 192.168.50.100, the first 99 addresses stay static. If you set the end to 192.168.50.200, you get a pool of 101 dynamic IPs.

Lease time sets how long a VM holds an IP. The default is often half an hour. In lab settings, you can pick 10–15 minutes. That way, IPs come back faster. For production-like tests, choose two hours.

VMware NAT Gateway, DNS Proxy, and Port Forwarding Configuration

NAT settings are the heart of VMnet8. When you click the NAT Settings button, you see the gateway IP and DNS proxy options. The gateway is usually the second address in the subnet. For example, 192.168.50.2. You can change this address. However, also update the default gateway on the VMs.

DNS proxy routes VM DNS queries through the host. If the “Auto detect available DNS servers” option is checked, VMware uses the host DNS settings. If you have a corporate DNS server, clear the box. Then enter the address manually. That way, DNS resolution stays central.

For port forwarding, click the Add button. These fields appear: Host port, Type (TCP/UDP), Virtual machine IP address, and Virtual machine port. For example, forward host port 8080 to VM port 80. Enter these values. That way, the http://host-ip:8080 address reaches the VM web server.

Port forwarding rules are also stored in the vmnetnat.conf file. You can edit this file manually. However, using the GUI is safer. After changes, restart the NAT service.

Subnet Clash Protocol: Working with VPN, WSL2, and Hyper-V

On modern Windows systems, more than one virtual network layer runs at the same time. Hyper-V, WSL2, and VPN clients create their own subnets.

VMware’s default subnets can clash with these layers. When a clash occurs, VMs lose internet access. Sometimes they also get an unidentified network error.

In this section, you will learn to spot and fix a clash. You will see separate methods for WSL2 and Hyper-V, and separate methods for VPN. Finally, we will share a subnet planning template that prevents clashes.

Spotting and Fixing VMware Subnet Clashes with WSL2 and Hyper-V

WSL2 uses the 172.16.0.0/12 range by default. Hyper-V can select different ranges for its own virtual switches. VMware’s VMnet8 usually sits in the 192.168.x.0/24 range. However, these ranges sometimes clash. Also, WSL2 can use 172.21.0.0/20, and Hyper-V can use 172.28.0.0/16.

To spot a clash, run this command in a command prompt:

ipconfig /all | findstr "IPv4"

Note the IPs of the VMnet8, WSL2, and Hyper-V adapters. If they sit in the same subnet block, that means a clash exists. For example, if VMnet8 is 172.20.0.1 and WSL2 is 172.20.0.2, a clash is certain.

To fix it, change the VMnet8 subnet. Select VMnet8 in Virtual Network Editor. Move the Subnet IP to a block outside WSL2, such as 192.168.200.0. Also update the DHCP scope for the new subnet. After the change, reboot the VMs.

As an alternative, you can change the WSL2 subnet. Add these lines to the %UserProfile%\\.wslconfig file:

[wsl2]\nnetwork=192.168.250.0/24

However, this method is more complex. Yet changing the VMware side usually gives a faster result.

If a clash with Hyper-V exists, bcdedit /set hypervisorlaunchtype off offers a temporary fix. However, this turns off WSL2. For a permanent fix, split the subnets.

Reconfiguring VMnet8 Gateway and Subnet in a VPN Subnet Clash

Corporate VPN clients add their own subnets to the routing table when they connect. If the VPN subnet is the same as VMnet8, VM traffic takes the wrong path. Therefore, the VM loses internet access. Sometimes you can also see an “unidentified network” error.

First, learn the VPN subnet. Look at the connection details of your VPN client. For example, if it uses the 10.0.0.0/8 range, move VMnet8 outside it. 192.168.250.0/24 can be a good choice.

Select VMnet8 in VMware Network Editor. Set the Subnet IP to 192.168.250.0. Set the gateway to 192.168.250.2. Move the DHCP scope to the 192.168.250.100–192.168.250.200 range, and save the changes.

Then restart the NAT service:

net stop "VMware NAT Service" && net start "VMware NAT Service"

Reboot the VM. While the VPN link is active, test the VM internet path. If the problem remains, check the VPN client “split tunneling” setting. If it sends all traffic to the VPN, VMware NAT traffic also goes over the VPN and clashes.

Virtual Network Subnet Planning Template to Prevent Clashes

The best fix is to prevent a clash from the start. The template below shows common ranges. On top of that, use this table as a reference for your virtual labs.

• VMnet1 (Host-Only): 192.168.10.0/24 — Isolated tests
• VMnet8 (NAT): 192.168.20.0/24 — Tests with internet access
• VMnet2 (Custom Host-Only): 192.168.30.0/24 — Security lab
• VMnet3 (Custom Bridged): DHCP from the physical network — Server simulation
• WSL2: 172.20.0.0/24 — Leave as default
• Hyper-V: 172.30.0.0/24 — Leave as default
• VPN client: 10.0.0.0/8 — Corporate policy

In this template, each layer sits in a different block. Therefore, the clash risk is minimal. Also, the subnet mask for each VMnet is 255.255.255.0, or /24. This gives 254 usable hosts and is easy to manage.

When you adapt the template to your own setup, do not forget this rule: all layers that run at the same time must sit in different subnet blocks.

If you plan with CIDR notation, adding a new segment becomes easier. For example, if you move in /24 blocks, you set aside the next block for each new VMnet.

Wi-Fi Bridging, Adapter Binding, and Windows Defender Firewall Blocks

Bridging over Wi-Fi is one of the most problematic cases. Also, bridged mode that works fine on wired links fails in a strange way on Wi-Fi. The VM cannot get an IP. It does not show up on the network. Sometimes the link drops continuously.

In this section, we will explain why Wi-Fi bridging is difficult. Then we will review how Windows Defender Firewall affects the “unidentified network” error. Finally, we will cover the auto adapter binding limit in multi-NIC setups.

VMware Bridging over Wi-Fi Does Not Work: Causes and Fix

Wi-Fi bridging is more complex than wired bridging. This is because wireless drivers handle 802.11 frames in a different way. VMware uses a special mode when it bridges a Wi-Fi adapter. However, not every driver supports this mode.

First, check which adapter VMnet0 bridges to in Virtual Network Editor. If Automatic is selected, VMware scans all active adapters. Even when the Wi-Fi adapter shows in the list, it sometimes picks “Microsoft Wi-Fi Direct Virtual Adapter”. Yet this virtual adapter does not carry real traffic.

To fix it, select VMnet0. Check your physical Wi-Fi card from the “Bridge to” menu. For example, “Intel(R) Wi-Fi 6 AX201 160MHz”. Turn off the “Automatic” option and save the change. Also, in 26H1 this setting can reset after a network reset. So check it from time to time.

If it still does not work, check your Wi-Fi driver for “promiscuous mode” support. Some drivers do not support this mode. In this case, use NAT mode instead of bridging. But NAT is not subject to the Wi-Fi limits. Your VM reaches the internet, but no one can reach it from outside.

Windows Defender Firewall and the ‘Unidentified Network VMnet8’ Error

VMnet8 sometimes shows up as “Unidentified network”. In this case, your VM has no internet access even if it gets an IP. Windows Defender Firewall treats this network as untrusted. It can block outbound traffic.

First, check the network profile. Run the Get-NetConnectionProfile command in PowerShell. If the VMnet8 profile is “Public”, make it “Private”:

Set-NetConnectionProfile -InterfaceAlias "VMnet8" -NetworkCategory Private

This command turns the network profile into a private network. That way, Windows Defender Firewall applies less strict rules. Then restart the VMware NAT service.

If the problem remains, add an exception for VMware in Windows Defender Firewall. Follow Control Panel > Windows Defender Firewall > Advanced Settings. Allow vmnat.exe and vmnetdhcp.exe in inbound and outbound rules.

In some cases, third-party security software can block it too. For example, network filters in products such as Kaspersky and ESET can block VMnet8 traffic. Turn them off for a moment and test.

Multi-NIC Bridging and the Auto Adapter Binding Limit

If you have more than one physical network card, bridging gets complex. In Automatic mode, VMware tries to bridge all cards. However, some cards (VPN, virtual adapters) are not suitable for this. This leads to wrong pairings.

Click the Automatic Settings button for VMnet0 in Virtual Network Editor. A list of all adapters appears. Clear the check box for cards you do not use. In particular, remove these:

• Microsoft Wi-Fi Direct Virtual Adapter
• VPN client virtual adapter (TAP, WireGuard, OpenVPN)
• Hyper-V Virtual Ethernet Adapter
• Loopback adapters

Leave only real physical Ethernet and Wi-Fi cards. That way, VMware picks the right adapter. If it still selects the wrong adapter, turn Automatic off completely. Select one card from the “Bridge to” menu.

If you want a second bridged network on a multi-NIC host, use VMnet2. Set VMnet2 to the “Bridged” type. Check a different physical card. That way, you get two separate bridged networks. Each one links to a different physical network.

VMware Workstation Advanced Network Features: VLAN Limits, Jumbo Frame, IPv6, and Promiscuous Mode

Network Editor offers advanced features beyond the basic settings. However, these features have limits. In VLAN tagging in particular, Workstation is not as flexible as ESXi. Also, MTU settings need manual input on Linux.

In this section, we cover the real limits of VLAN. Also, we show jumbo frame configuration. In addition, we review IPv6 support. Finally, we explain the security effects of promiscuous mode. In other words, you will find practical steps in each heading.

Can VMware Network Editor Do VLAN Tagging? Real Limits

Short answer: no, there is no direct VLAN ID field. It has no VLAN tagging field. Workstation does not offer VLAN trunk configuration like ESXi. This is because Workstation is a desktop hypervisor.

So how do you perform VLAN segmentation? There are indirect methods. First, you define VLANs on your physical switch. Assign the physical port your virtual machine uses to the right VLAN. That way, the VM becomes a member of that VLAN. However, this is segmentation by host port, not by VM.

The second method is to use custom VMnet networks. Each VMnet forms its own broadcast domain. This is not as flexible as VLAN, but it gives logical isolation. For example, set VMnet2 as “production” and VMnet3 as “test”. That way, no routing occurs between the VMs.

The third method is VLAN configuration inside the guest OS. Create a VLAN interface in Linux or Windows. However, this depends on 802.1Q trunk support on your physical switch.

In particular, VMware Workstation passes these frames through in a transparent way. Still, this method needs advanced network knowledge. The host sometimes strips 802.1Q tags.

Jumbo Frame and MTU Settings on Linux: 68–9194 Byte Range

Jumbo frame goes above the standard 1500-byte MTU. You send frames up to 9000 bytes. This cuts CPU load in large data transfers. However, the whole network chain must support the same MTU.

To change the MTU of a VMnet adapter on Linux, use the ip command:

sudo ip link set dev vmnet8 mtu 9000

This command raises the MTU of the VMnet8 adapter to 9000 bytes. However, this is a temporary change. It resets on reboot. To make it permanent, add it to your network config file. For example, if you use Netplan:

network:\n  version: 2\n  ethernets:\n    vmnet8:\n      mtu: 9000

The MTU range is 68 to 9194 bytes. 68 is the minimum. 9194 is the top limit that VMware supports. Administrators usually use 9000 for jumbo frames. However, your physical switch and routers must also support 9000 MTU. Otherwise, packets fragment and performance drops.

Set the MTU inside the VM too. The guest OS gets the virtual adapter MTU on its own. However, manual input is sometimes needed.

On a Linux VM, run ip link set dev ens33 mtu 9000. On Windows, set the “Jumbo Packet” value to 9014 in the network adapter properties.

IPv6 Subnet Support and the Practical State in Virtual Network Editor

IPv6 support is limited in Workstation. It has no separate subnet field for IPv6. On top of that, NAT mode does not route IPv6 traffic by default. In Bridged mode, your VM can get IPv6 if your physical network hands it out.

In Host-Only mode, IPv6 configuration is fully manual. To define an IPv6 address on VMnet1, make a static configuration inside the guest OS. VMware does not offer DHCPv6 or SLAAC for IPv6 on this network.

In practice, most labs sit on IPv4. For IPv6 tests, bridged mode gives the best result. If your physical network hands out IPv6, your VM gets it on its own too. In NAT mode, IPv6 may not work. So choose bridged mode in cases that need IPv6.

Promiscuous Mode: Packet Capture and Security Warnings

Promiscuous mode makes the virtual switch pass all packets to the VM. Normally, the switch passes only packets that go to the target MAC address. In this mode, you see all broadcast traffic. You need it to capture packets with tools such as Wireshark.

On Windows, promiscuous mode is off by default. To turn it on, select the VMnet in Virtual Network tool. Check the Allow All option from the Promiscuous Mode menu. However, this carries a security risk. In this mode, all VMs on the same host can see this traffic.

On Linux, the situation is more complex. Give access rights to the /dev/vmnet0 device. The udev rule we covered earlier applies here. Also, turn on promiscuous mode in the VM network adapter settings.

Security warning: promiscuous mode creates a data leak risk in corporate settings. Do not turn this mode on in networks that carry sensitive data. Use it only in isolated labs and authorized tests. Also, store the data you capture in a safe place.

VMware Configuration Backup, Migration, and Restore Defaults Risks

Your virtual network configuration is an architecture you have worked to build. You do not want to lose it. Luckily, Virtual Network Editor offers backup with the Export and Import buttons. Also, you can do the same job from the command line with vnetlib64.exe.

However, the Restore Defaults button carries serious risks. It deletes all your custom settings. On top of that, it can break the bridged network. In this section, we will review safe backup methods and the real effects of Restore Defaults.

Backing Up and Moving Virtual Network Configuration with Export/Import Buttons

The Export button writes all VMnet configuration to one file. Open Virtual Network Editor. You see the Export button at the bottom. Choose the file name and location. For example, D:\\yedek\\vn_config.txt.

After the file is created, keep it in a safe place. This file holds all subnet settings, DHCP scopes, and NAT rules. Use the same file to move them to another computer. Open VMware Network Editor on the target computer. Click the Import button and select the file.

The import operation overwrites the current configuration. So back up the current settings on the target computer first. Also, VMs must be off during import. After the process ends, restart the services. That way, the changes take effect right away.

For command-line backup, use the vnetlib64.exe -- export command. Run it in an admin command prompt as we covered earlier. This method is ideal for automation scripts.

For example, you can take a daily backup with a PowerShell script. As a result, a configuration backup can be invaluable during network outages.

What Does Restore Defaults Do and Why Not Use It While a VM Is On?

The Restore Defaults button returns all virtual network settings to factory values. This button recreates VMnet0, VMnet1, and VMnet8.

Also, it deletes custom VMnets and clears DHCP scopes and NAT rules. In short, every change you made after install is lost.

Use this button mainly when network configuration is fully broken. For example, if VMnet8 turned into an unidentified network and other methods fail, Restore Defaults can be the last resort. But always take a backup first.

The most critical warning: do not press Restore Defaults while a VM is on. Broadcom’s official documentation warns about this too. Resetting the bridged network while a VM runs cuts the network link at once. This can lock the VM or lead to data loss.

The right order is this: first shut down all VMs. Take a backup, and then press Restore Defaults. Then restore the backup with Import. These steps give a reset with minimum outage. If you have no backup, set all options from scratch.

Critical Points Competitors Miss: 6 Common Myths About Virtual Editor

Most sources online repeat the same superficial information. However, the facts I encounter in the field are different. In this section, we will cover the six most common myths. Instead, I will debunk each one with my own experience.

These myths can cost you hours. If you start with wrong information, you look for the fix in the wrong place. So read this section with care. Perhaps the answer you need is here.

Myth 1: ‘You Can Enter a VLAN ID in Virtual Network Editor’ — Workstation Has No Such Field

Many blog posts claim it has a VLAN ID field. This is completely false. Workstation has no such field.

ESXi vSphere Client has a VLAN ID box. However, Workstation does not offer this feature because it is a desktop product.

If you want VLAN segmentation, use custom VMnet networks. Each VMnet forms its own isolated broadcast domain. This is not as flexible as VLAN. But it gives enough isolation at lab scale. Also, define VLANs on your physical switch and assign the host port to that group.

Myth 2: ‘Player Has No Network Editor at All’ — Moving to Pro and the Limits of the Manual Method

Workstation Player has no this interface. However, the install package contains the vmnetcfg.exe file. You can extract and run this file manually.

The method is this: run the installer with the /e key. Open the network.cab file. Copy the vmnetcfg.exe file to the Player folder.

However, this method has serious limits. First, the vendor officially ended the Player release. Second, manual extraction does not work in every release.

Third, you get compatibility issues with updates. The cleanest fix is to move to free Workstation Pro. Also, Broadcom has offered Pro for free since 2024. You do not even need a license key.

Myth 3: ‘Restore Defaults Is Harmless’ — The Damage It Can Do to the Bridged Network

Restore Defaults is not as harmless as it looks. It deletes all your custom VMnets. It wipes your DHCP reservations. Also, it clears your NAT port forwarding rules. On top of that, if VMs are on, the bridged network takes serious damage.

The Broadcom documentation warns in clear terms: do not press Restore Defaults while a VM is on. This is because the bridge link cuts at once. Therefore, the VM network driver can lock. In this case, even a VM reboot may not fix it. Sometimes you reload all virtual network drivers.

Myth 4: ‘Virtual Network Editor Is Only a GUI’ — The vnetlib and Registry Truth

The GUI is only a shell. The real power sits in vnetlib64.exe and Registry keys. In fact, when the GUI will not open or freezes, the command line can help. Repair your network with export/import, set commands, and reinstall.

Also, the HKLM\\SYSTEM\\CurrentControlSet\\Services\\VMnetDHCP key in the Registry is the real source of the DHCP scope. The values you see in the GUI are read from here. You should know this layer for advanced troubleshooting.

Myth 5: ‘Linux Has No Network Editor’ — vmware-netcfg Shows Otherwise

Linux users often say “this tool exists only on Windows”. That is not true. In particular, the vmware-netcfg command offers a fully working vmware network editor on Linux. Open it by typing sudo vmware-netcfg in a terminal. The same GUI window appears.

On top of that, configuration files on Linux are more transparent. Edit the /etc/vmware/networking file directly. Also, reload changes with the vmware-networks service. This gives a significant advantage for automation and remote management.

Myth 6: ‘Network Management Did Not Change in 25H2’ — Import/Export and License Impact

The 25H2 release brought major changes to network management. The developers added Import and Export buttons. This made configuration backup and migration easier.

Also, with 26H1, Workstation moved fully to a 64-bit architecture. All binaries and services run as 64-bit.

Licensing also changed significantly. Broadcom made Workstation Pro free starting in November 2024. License keys are not needed in 17.5.2 and later releases. This is a major opportunity to escape the network limits in Player.

Moreover, the 64-bit structure of 26H1 makes the use of vnetlib64.exe mandatory. In other words, 32-bit tools no longer work.

Virtual Network Editor or ESXi/vSphere? Decision Tree and Boundary Drawing

Workstation and ESXi work at different scales. Workstation is ideal for building a lab on one host.

ESXi is an enterprise virtualization platform. On top of that, it is the network brain of Workstation. On ESXi, we use vSwitches and port groups.

So which one should you choose, and when? In this section, we will present a decision tree. We will make clear when Workstation is enough and when you need to move to ESXi.

When Is Virtual Network Editor Enough?

In the cases below, Workstation and the network editor are enough:

• Single-user lab: build an isolated test setup on your own computer.
• Penetration testing training: run Kali Linux and target VMs on the same host.
• Software development: test an app on different operating systems.
• Small demo: a few VMs are enough to show a product to a client.
• Teaching and training: let students run experiments on their own machines.
• Fast prototyping: try a network topology fast.

The common point of these cases is one host and a limited number of VMs. It gives full control at this scale. Build the topology you want with DHCP, NAT, and custom VMnets. Also, there is no extra license cost.

When Should You Move to ESXi/vSphere?

Workstation falls short in these cases. Therefore, the time comes to move to ESXi/vSphere:

• Multi-host management: manage more than one server from one center.
• High availability (HA): VMs move on their own when a host fails.
• vMotion: move running VMs with no outage.
• Distributed vSwitch (vDS): manage central network policy for hundreds of VMs.
• VLAN trunk and scaling: you need advanced VLAN and large-scale networking.
• Production workloads: host critical apps that run 24/7.

ESXi is built for these needs. It offers full network control with vSwitches, port groups, and VLAN IDs. However, management complexity and cost go up. Balance scale, budget, and operational needs when you decide.

VMware Virtual Network Editor FAQ

Conclusion: Operational Maturity in Virtual Network Editor

The Virtual Network tool is a much deeper tool than it looks. It is not limited to changing a few fields in the GUI. Instead, it turns into a full control center with the command line, Registry, and Linux files. We covered every layer in this guide.

Operational maturity rests on these three principles: back up first, make changes, and verify afterward. Build an export/import habit. Make changes while VMs are off. Restart services. In practice, this simple discipline prevents outages that last hours.
