Windows Firewall block WSL2 accessing to Windows service

[eromoe]

Test code:

winip=$(ip route | grep default | awk '{print $3}')
ping $winip

result:

Actually I want to use a proxy service host on windows . I saw many people success with above command, why I faied ? Or wsl2 go into new problem ?

There isn't enough to go on here to guess why you can't ping your default route on (if I am interpreting correctly) WSL1.

I can provide what you need if you tell me how to do , I have totally no clue to investigate it .

I found it due to windows firewall. Add exclude rule of wsl.exe in firewall didn't work, I saw several cases include me had to shutdown firewall to make wsl able to access windows service .

Since this is common usage of wsl2, people shouldn't need shutdown firewall . It is system/wsl resposibility to make wsl2 bypass firewall at default .
