Describe the problem

First, thank you for the excellent software!

I have netbird running inside wsl2. It connects fine, but no traffic seems to pass. Forcing user space wireguard as described in https://docs.netbird.io/how-to/troubleshooting-client#enabling-wire-guard-in-user-space makes everything work, but I don't see any way to enable this for good in the configuration. I'm not sure why no traffic is flowing in kernel mode, but I don't really care about that as long as user mode works.

To Reproduce

Steps to reproduce the behavior:

Install netbird in wsl2
Connect to a peer
Connection works, but traffic doesn't flow.

Expected behavior

It should work :)

Are you using NetBird Cloud?

This is self-hosted.

NetBird version

0.26.2

Have you tried adding NB_WG_KERNEL_DISABLED=true to your bashrc? This is just an environment variable that netbird should pick up automatically.
