WSL port forwarding

I'm trying to connect to a vite dev server running in WSL from my phone on the same local network, but it does not seem to want to connect some commands I tried to run :

netsh.exe interface portproxy add v4tov4 listenport=5173 connectport=5173 connectaddress=$((wsl hostname -I).Trim())

netsh interface portproxy add v4tov4 listenport=5173 listenaddress=0.0.0.0 connectport=5173 connectaddress=(wsl hostname -I)

netsh advfirewall firewall add rule name="Open Port 5173" dir=in action=allow protocol=TCP localport=5173

netsh interface portproxy add v4tov4 listenport=5173 listenaddress=0.0.0.0 connectport=5173 connectaddress=172.30.240.1

netsh.exe interface portproxy add v4tov4 listenport=5173 connectport=5173 connectaddress=$((wsl hostname -I).Trim())

netsh interface portproxy add v4tov4 listenport=5173 listenaddress=0.0.0.0 connectport=5173 connectaddress=(wsl hostname -I)

netsh advfirewall firewall add rule name="Open Port 5173" dir=in action=allow protocol=TCP localport=5173

netsh interface portproxy add v4tov4 listenport=5173 listenaddress=0.0.0.0 connectport=5173 connectaddress=172.30.240.1

172.30.240.1 is the ip of the WSL instance as reported by ipconfig /all

[wsl2]

https://learn.microsoft.com/en-us/windows/wsl/wsl-config <-- try setting networkingMode to something else https://learn.microsoft.com/en-us/windows/wsl/networking <-- also check this try the mirrored mode

PS C:\Users\ragnar> wsl.exe --distribution Ubuntu-24.04 hostname -i
127.0.1.1

PS C:\Users\ragnar> wsl.exe --distribution Ubuntu-24.04 hostname -i
127.0.1.1

https://learn.microsoft.com/en-us/windows/wsl/networking#mirrored-mode-networking yeah, that's fine

Rägnar O'ockOP•2w ago

"Port 5173 is in use, trying another one..." well... it did something but not what I wanted...

ἔρως•2w ago

yeah, it's something maybe a restart

Rägnar O'ockOP•2w ago

ah it's the proxy settings I've added above let's remove them

Rägnar O'ockOP•2w ago

Yeay it works! (It's mighty broken, but it works)
