Repro Steps

Run some kind of server on Windows on loopback address which is not 127.0.0.1, for example:
python3.exe -m http.server -b 127.128.0.11 11224

Forward that address and port to localhost:
netsh interface portproxy add v4tov4 listenaddress=127.0.0.1 listenport=11224 connectaddress=127.128.0.11 connectport=11224

Try to access the forwarded port from Windows, for example:
wget localhost:11224 (this works for me)

Try accessing that port from WSL:
wget ${HOST}.local:11224 (this doesn't work for me, connection times out)

Note that if I run the server directly on 127.0.0.1:11224, it works correctly.

Expected Behavior

I expected to be able to access the forwarded port.

Actual Behavior

I get connection timeout.

If I'm reading this correctly this is by design. On ipv4 only binds on 127.0.0.1 or 0.0.0.0 have port forwarding.

I see, thanks for the feedback. I thought I could work around this with forwarding.
