NAT and Port Forwarding are different, but often used in conjunction with each other. NAT is Network Address Translation. It translates traffic from one IP to another. An example: NATing your WAN IP 1.2.3.4 to your internal webserver 192.168.0.1. Port forwarding (sometimes called PAT - Port Address Translation) is similar, but it functions on the port level. You can forward port 80 from your WAN IP to your internal webserver, for example. You can also forward to a different port - i.e. port 8080 on the WAN is forwarded to port 80 on your internal web server. |
