🙂netsh interface portproxy

💻

Netsh interface portproxy is a command that allows you to act as a proxy between IPv4 and IPv6 networks and applications¹. You can use it to listen for messages on a specific port and IPv4 address and forward them to another port and address¹.

Some examples of netsh interface portproxy commands are:

• netsh interface portproxy add v4tov4 listenport=12345 connectaddress=HOST-B : This command will forward any messages received on port 12345 of the local computer to HOST-B⁴.
• netsh interface portproxy add v6tov4 listenport=80 connectaddress=192.168.0.1 connectport=8080 : This command will forward any messages received on port 80 of the local IPv6 address to port 8080 of 192.168.0.1³.
• netsh interface portproxy show all : This command will show all the current port proxy settings³.

Listen on ipv4:             Connect to ipv4:

Address         Port        Address         Port
--------------- ----------  --------------- ----------
