I followed the directions at https://stuartleeks.com/posts/wsl-ssh-key-forward-to-windows/ https://stuartleeks.com/posts/wsl-ssh-key-forward-to-windows... to get the combination of socat and npiperelay to work for this purpose. I did slightly deviate from his final script by using pgrep instead of the combination of ps and grep to detect if npiperelay was already running. Edit: These directions are very similar to those linked in the comment this is in reply to and either will work.
