wsl2 network didn't work if host ethernet working with vlan

[comicfans]

Environment

Windows build number: Microsoft Windows [版本 10.0.19041.508]
Your Distribution version: Release:        20.04
Whether the issue is on WSL 2 and/or WSL 1: Linux version 4.19.104-microsoft-standard (oe-user@oe-host) (gcc version 8.2.0 (GCC)) #1 SMP Wed Feb 19 06:37:35 UTC 2020

Steps to reproduce

WSL logs:

Expected behavior

if host network works, wsl2 network should work out of box

Actual behavior

if my host network working at vlan mode (host ethernet has vlan id configured), host network everything works(no matter ping/tcp/udp), but wsl2 can not reach any network except host peer (host <-> wsl2 can communicate with each other, but wsl2 can not reach upstream router, or anyother node out of host),

then I reconfigure my host network to non-vlan mode (host ethernet has no vlan id), host network everything works, and wsl2 network also worked.

Yes this! This has taken three hours of my life!

I’m assuming what is happening here is that WSL2 network adapter is being bonded to my untagged interface which has no gateway meaning my packets go nowhere.

Is this fixable by setting a vlan ID in the guest OS?

Hello, any update ?

Please collect WSL logs and post the backlink to the feedback item here. Also please identify any third-party networking software that has been installed on Windows if applicable.

I've got the same issue. One additional bit of context I can add is that I can connect just fine from Docker containers running in docker desktop. Those should be backed by WSL2 so I'm really confused about what could be different between that and my WSL Ubuntu. Here's the output of network.bat I'm not sure how to include wsl.etl since it appears to be a binary file.
