Repro Steps

I've set this values in .wslconfig file

[wsl2]
memory=4G
[experimental]
autoMemoryReclaim=gradual
sparseVhd=true
networkingMode=mirrored
dnsTunneling=true
firewall=true
autoProxy=true

however, when I do:

> wsl --shutdown
> wsl
$ ip a

I can see just the loopback interface is shown:

$ ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever

Expected Behavior

I would expect just with networkingMode=mirrored ... the output of ip a shows the very same network interfaces and config than Windows 11.

Actual Behavior

As you can see in my pasted output, ip a just shows loopback interface, so networking is not available inside WSL.

Can you collect logs per these instructions?

https://github.com/microsoft/WSL/blob/master/CONTRIBUTING.md#collect-wsl-logs-for-networking-issues

[jfernandz]

sure @pmartincic, but the whole zip is 88MB large, so ... where should I upload it? Do you want some particular file from inside the zip?

@jfernandz, Does it not let you upload here?

Max is 25Mb, so I cannot 😞

@jfernandz: See if you're in the same boat as me from this post and the information from J0F3.

#11002

We had some GPO in our domain that was disabling IPv6 as mentioned by J0F3. When I got rid of the value, networkingMode=mirrored started working and showed the mirrored interfaces for me. We are working internally with the organization to disable this registry GPO that is disabling IPv6 since that's not best practices.

Thank you so much, I have struggle with this for hours.
