Repro Steps

I tried Windows, WSL, and distro clean installation, so I don't know how to reproduce it.

I can't access the internet from WSL without using a VPN. The ping command works, but other activities don't.

thanks for reporting the issue and sending logs In the windows packet capture I did not see traffic coming from WSL (I did not see traffic with source 172.17.224.86, which is the IP assigned in Linux). I also did not see traffic with the IP from your screenshot (217.160.0.201)

to make sure I understand the issue correctly, does curl google.com work when the VPN is connected? and it does not work when the VPN is disconnected? could please collect a new set of networking logs where you do the following? start networking logs have the VPN disconnected curl google.com in WSL, confirm it does not work connect the VPN curl google.com in WSL, confirm it works stop networking logs

some other things that would be useful to know: what is the name of the VPN product you are using? does the problem happen when using networkingMode=mirrored?

I'm not sure about this. I just ran everything described in the readme and uploaded it. to make sure I understand the issue correctly, does curl google.com work when the VPN is connected? and it does not work when the VPN is disconnected? could please collect a new set of networking logs where you do the following? start networking logs have the VPN disconnected curl google.com in WSL, confirm it does not work connect the VPN curl google.com in WSL, confirm it works stop networking logs

I have already provided the screenshots. The top one is without a VPN, and the bottom one is with a VPN, which is working. I will include logs for both situations. some other things that would be useful to know: what is the name of the VPN product you are using? does the problem happen when using networkingMode=mirrored?

Any type of VPN works. It doesn't matter which one. Also, no, the problem doesn't occur when using networkingMode=mirrored
