What Is Port Forwarding?

Port forwarding is the process of redirecting a network service to an IP address on a different local area network. “port” refers to the transport layer protocol that carries data from one computer to another. Usually, this means TCP/UDP ports like port 80 or 443 for HTTP and HTTPS, respectively. It can also refer to other protocols such as FTP passive mode, which uses ports 20 and 21 by default. It’s because the destination server listens on these specific ports that we use them for forwarding purposes. This article will discuss what exactly port forwarding is and how you can set up your router to do it yourself without any additional help or assistance from others.

Because port forwarding forwards traffic on a one-to-one basis, you may wish to use something called NAT instead. This allows you to forward all of your devices’ network traffic in just the same way using a shared external IP address.
