Can't port forward/port map from Hyper-V VM to Host IP Address via Virtual Switch NAT
For some reason, port forwarding via adapter settings did not work for me, but using netsh from the command line did:
netsh interface portproxy add v4tov4 listenport=3000 listenaddress=0.0.0.0 connectport=3000 connectaddress=192.168.137.2
