Introduction: Quick guide to fix Wsl2 not working with VPN

Quick fact: VPNs can block or reroute traffic in a way that breaks the WSL2 network interface.
If you’re seeing DNS resolution failures, no internet access from WSL, or Windows–WSL2 networking disconnects when the VPN connects, you’re in the right place.
Here’s a concise, actionable path:
- Step 1: Verify network adapters and DNS behavior
- Step 2: Adjust WSL2’s network settings or reset the interface
- Step 3: Configure VPN to allow split tunneling or enable network bridge
- Step 4: Rebind WSL2 to the VPN’s DNS or use a custom resolver
- Step 5: Test with simple ping and DNS lookups

Understanding the problem: how VPNs affect WSL2 networking

WSL2 runs inside a lightweight VM with its own network stack, bridged to Windows via a virtual Ethernet adapter vEthernet. When a VPN connects, Windows often rewrites routing tables and DNS settings, which can isolate or block the WSL2 VM’s network.
Symptoms you might see:
- WSL2 cannot reach the internet or specific hosts
- DNS resolution fails inside WSL2 cat /etc/resolv.conf returns a non-responsive DNS
- VPN connection drops or WSL2 loses connectivity after VPN reconnects
- Localhost services or server apps inside WSL2 aren’t accessible from Windows

Quick checks to confirm the issue

Check Windows network adapters:
- Open Command Prompt and run: ipconfig /all
- Look for the vEthernet WSL adapter and note its IP range often 172.27.x.x
Check WSL2’s IP from within WSL:
- In PowerShell, run: wsl -e ip addr
- Confirm the WSL2 interface has an IP and can ping Windows host ping -c 4 172.27.240.1 or similar
DNS test inside WSL2:
- Resolve a domain: dig github.com or nslookup github.com
- If that fails, check /etc/resolv.conf; it’s often symlinked to /run/resolvconf/resolv.conf or inherits from Windows
VPN-specific checks:
- Disconnect VPN, verify WSL2 can access the internet again
- Reconnect VPN, retry WSL2 connectivity
If you use a domain-specific service in WSL2 like Docker Desktop’s WSL2 mode, verify that the service is listening on the expected interface and port.

Fixes that work for most VPNs

Fix A: Reconfigure DNS for WSL2
- Edit /etc/resolv.conf in WSL2 to point to a reliable DNS server Google DNS 8.8.8.8, 8.8.4.4 or Cloudflare 1.1.1.1
- Example:
  - sudo nano /etc/resolv.conf
  - nameserver 8.8.8.8
  - nameserver 8.8.4.4
- If the file is read-only due to auto-generation, disable the auto-resolv.conf generation:
  - In WSL2, edit /etc/wsl.conf and add:
    generateResolvConf = false
  - Then create /etc/resolv.conf with your preferred nameserver
Fix B: Enable or adjust Windows’ VPN split tunneling
- Some VPNs offer split tunneling to allow local network access or specific apps to go through VPN. In the VPN app:
  - Enable split tunneling for WSL-related traffic if available
  - Or ensure WSL traffic is routed through VPN by explicitly adding routes
Fix C: Create a static route to allow WSL2 to reach VPN networks
- Open PowerShell as Administrator
- Determine VPN gateway usually something like 10.x.x.x or 198.18.x.x
- Add a route for WSL2 subnet 172.27.0.0/16 is common
- Command example:
  - route add 172.27.0.0 mask 255.255.0.0 metric 1
- If the VPN changes routes on reconnect, you may need a script to re-apply the route after VPN reconnects
Fix D: Reset WSL2’s networking
- Close all WSL2 instances
- In PowerShell, run:
  - wsl –shutdown
- Then disable and re-enable the WSL feature:
  - dism.exe /online /disable-feature /featurename:VirtualMachinePlatform /norestart
  - dism.exe /online /disable-feature /featurename:Microsoft-Windows-Subsystem-Linux /norestart
  - Reboot
  - Re-enable features:
  - dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /norestart
  - dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /norestart
- Start WSL2 again and check connectivity
Fix E: Use a VPN client that supports WSL2-friendly networking
- Some VPNs have known issues with Linux VMs. Check vendor knowledge base for WSL2 compatibility, recommended settings, and updates
Fix F: Update Windows and WSL2 kernel
- Ensure Windows 11/10 is up to date
- Update WSL2 kernel package https://aka.ms/wsl2kernel
- Reboot after updates
Fix G: Use a bridge network or host-only adapters
- In some setups, you can configure Windows to bridge the VPN and WSL2 network adapters. This is advanced and varies by VPN client and Windows version
Fix H: Check firewall rules
- Ensure Windows Defender Firewall or third-party firewall isn’t blocking WSL2 traffic when VPN is connected
- Create a rule to allow outbound/inbound traffic for WSL2 processes e.g., wsl.exe, wslhost
Fix I: Use a dedicated DNS resolver inside WSL2
- Install a lightweight resolver like dnsmasq or stubby inside WSL2
- Start the resolver and point /etc/resolv.conf to 127.0.0.1
- Then configure the VPN/Windows to forward DNS queries to WSL2
Fix J: Check the VPN’s DNS leakage protection settings
- Some VPNs force all DNS requests through VPN, which can break WSL2 if Windows DNS isn’t synced. Disable DNS leakage protection if it causes issues, or set WSL2 to use a static DNS as described above

Step-by-step guide: resolving in 15 minutes

Step 1: Test baseline without VPN
- Ensure WSL2 is healthy: open a Linux shell, run ping 8.8.8.8 and ping google.com
Step 2: Connect VPN and observe
- Note any immediate DNS or connectivity changes
Step 3: Update DNS in WSL2
- sudo nano /etc/resolv.conf
- Add: nameserver 1.1.1.1
- Save and test: dig example.com
Step 4: If DNS works but other traffic fails, adjust routes
- Identify VPN gateway and add routes for WSL2 subnet
Step 5: Reboot and test
- Reboot Windows if necessary to solidify route changes
Step 6: Validate with real tasks
- SSH into a server from WSL2, access a web app, or pull a Git repo

VPN-specific tips and known issues

NordVPN
- NordLynx can interfere with WSL2 DNS. Try switching to protocol that doesn’t DNS leak, or disable IPv6 in NordVPN settings
- Use split tunneling to exclude WSL2 from VPN if you need direct access to local resources
ExpressVPN
- ExpressVPN sometimes changes the DNS resolver. Set /etc/resolv.conf manually and disable automatic DNS in the VPN app
- Use the “VPN split tunneling” feature to route WSL2 traffic outside VPN when needed
Surfshark
- Surfshark’s VPN for Windows may alter the WSL2 interface. Ensure you’ve updated to the latest client and consider a manual DNS setup inside WSL2
Private Internet Access PIA
- PIA often provides robust split tunneling. If WSL2 is blocked, create a route to Windows’ default gateway for your WSL2 subnet

Advanced tips: Docker, WSLg, and localhost

Docker Desktop with WSL2
- If you run Docker inside WSL2, ensure the Docker Desktop settings allow using WSL2 as the engine. VPNs can cause DNS conflicts, so set Docker to use the WSL2 host network path
WSLg GUI apps
- If WSLg apps fail to connect when VPN is on, it’s usually DNS or route-related. Fix DNS first, then test GUI app connections
Localhost and port forwarding
- If you’re exposing a service from WSL2 to Windows, ensure your Windows firewall allows the traffic, and consider using the IP address of the WSL2 interface for consistency
