Feature request: DNS resolution

[s-seidel]

Would it be possible to add a DNS resolver to wsld? I imagine that one could then set /etc/resolv.conf to 127.0.0.1 and wsldhost.exe would perform the DNS lookup on the Windows host. That would solve a lot of issues with the current state of it, for example that the Windows Firewall blocks the WSL interface by default.

What's the issue with DNS lookup in WSL? I haven't observed any weird with it.

There are workarounds, but for example my employer forces a firewall that doesn't allow exceptions for the WSL network interface, so most of those workarounds don't work for me.

Wouldn't setting the DNS server in WSL to the same server used by Windows work?

[s-seidel]

Well, but that changes depending on which network the host is connected to and also doesn't work with VPN and split DNS for example.

also doesn't work with VPN

No it does. I have WSL2 DNS happily working together with OpenVPN connection. And you even can access VPN resources from WSL2.
