NETSH port forwarding from local port to local port not working

I managed to get it to work by issuing:

netsh interface ipv6 install

Also, for my purpose, it is not required to set listenaddress and better to set connectaddress=127.0.0.1, e.g.

netsh interface portproxy add v4tov4 listenport=8001 connectport=80 connectaddress=127.0.0.1
