I was looking for

wsl-proxy.exe

instead of

wslrelay.exe

. I do see some ports being relayed/proxy on Windows that are also being listened to within

rdctl shell

. I'm not seeing my UDP ports (which I modified RD's

iptables.go

to add support), but I'm guessing that's a me problem

We set up a network namespace within our WSL distro (because WSL shares the network across all distributions, so stopping and immediately restarting Rancher Desktop sometimes causes network errors when things aren't torn down properly. The namespace ensures the teardown is complete).

wsl-proxy

is used to expose listening ports to the default WSL network namespace. There's also

host-switch.exe

that does the same on the Windows (host) side.
