"Here is an example on how to use
netsh interface portproxy to forward all requests that came to local IP on port 25 to 192.168.0.100 on port 80. Remember to enable IPv6!
netsh interface portproxy>add v4tov4 listenport=25 connectaddress=192.168.0.100 connectport=80 protocol=tcp
You can find more information about the commands here.
If it doesn't work you can use a software for this kind of job. For example if you need to use connectaddress=127.0.0.1 it will not work."
