Port forwarding in Windows

I’ve been messing around with Jekyll for a bit and was wondering how I could get port forwarding to work under Windows,
so that I could access port 4000 gracefully via port 80.

here we go to start

netsh interface portproxy add v4tov4 listenport=4000 listenaddress=172.29.166.87 connectport=80 connectaddress=192.168.1.115

here we go to delete it again

netsh interface portproxy delete v4tov4 listenport=4000 listenaddress=172.29.166.87
