Repro Steps

>bash
wsl: Mirrored networking mode is not supported: Windows version 26200.7171 does not have the required features.
Falling back to NAT networking.
wsl: Failed to configure network (networkingMode Nat), falling back to networkingMode VirtioProxy.
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

Expected Behavior

I'm trying to get mirrored or NAT networking working so I can use vscode server on the remote instance. It's unable to connect and through a lot of Googling i find it won't work on VirtioProxy. I am unsure why I can't get NAT or mirrored to work. I have confirmed that I have all network services running and the enabled features. This was working before but has broken on a recent windows update (25H2) that I installed yesterday.

Actual Behavior

Networking didn't setup properly
