I have installed WSL2 on my corporate laptop (Windows 10 Enterprise version 1909). When my laptop is on a corporate VPN (Global Protect) with full tunneling, I lose network connectivity from the WSL2. I cannot do DNS lookup and also I cannot cURL to any website.

Everything works fine when my host laptop is off a VPN.

Note: WSL2 is using Hyper-V with Internal virtual switch.

    Most likely the corporate VPN does not do or allow split tunneling. So when it is active, all network traffic goes through the tunnel. Your guest machine is likely on a different network (NAT).

  • Thanks, John. Is there a way change the NAT to the VPN Ethernet? Surprisingly, when I use DockerDesktop which also creates a VM and networking under the hood, the network connectivity works well from that VM while on the VPN.

    That is probably up to your Company Administration. It depends on how they set up the tunnel.

  • there are many people, including me, facing similar issue. check this github.com/microsoft/WSL/issues/5068 I'm afraid there is no solution.

  • If this is something that brings value to your Company, ask if they will install VMware Workstation on it or enable Hyper-V on and allow you to install Linux as a guest machine . VMware has excellent networking facilities and that will likely help you here.
