For ssh access you can create a port forward on the Windows host like this:

Open an Administrator CMD prompt

netsh interface portproxy add v4tov4 listenaddress=windows_host_ip listenport=22 connectaddress=localhost connectport=22

Then you can connect to windows_host_ip:22 and access the WSL 2 instance.

Hi @fanthos this is by design. Does this block a certain scenario or workflow for you?? (This scenario isn't supported in NAT either).

If it does, could you open a feature request for us? I'd love to know more about the scenario on why you need this. Thank you!

I meet the same question, here is why I need to access WSL2 listened port by IP on host machine:

I run a web service on my WSL2 for coworkers in the same office, and I need to use it also, when I told others to "access 192.168.1.4:8000 to use it", but I need to access localhost:8000 instead 192.168.1.4:8000, if I copy the link in my browser address bar, others get localhost:8000 which they cannot arrival the right place.
