Port forwarding or port mapping is a technique used in computer networking to translate an address and port number combination into another, so packets can be sent from one address to another while they are traversing a network gateway, such as a router.
By using port forwarding, you can connect to your network’s public services, such as web servers, FTP servers, e-mail servers, and other specialized Internet applications. The router forwards these requests to the appropriate computer when users send them over the Internet.
What Is Port Forwarding And Why Is It Used?
The purpose of forwarding port is to keep unwanted traffic from entering the network. Administrators can use one IP address for all external communications on the Internet, while dedicating multiple servers with different IP addresses and ports to the task internally, thus saving time and resources.
What Is Meant By Port Forwarding In Networking?

What Is Port Forwarding In Simple Terms?
In network forwarding, also known as port mapping, a network port is forwarded from one network node to another by forwarding it. By using this technique, an external user can access a private IP address (inside a LAN) from the outside using a NAT-enabled router.
Why Do I Need To Port Forward?
Public IP addresses can be preserved by port forwarding. In addition to protecting servers and clients from unwanted access, it can hide the services and servers available on a network and limit access to and from it.
