Port Fowarding

Introduction to Port Forwarding

Port forwarding is a network technique used to allow external devices to access services on a private network by mapping a specific port on a router or firewall to a device or service inside the network. It’s commonly used for things like hosting web servers, gaming, or accessing remote desktops.

When a request is sent to a router on a specific port, the router forwards the request to the device or server inside the network that is listening on that same port. This allows external traffic to interact with the service even though it's behind a NAT (Network Address Translation) or firewall.

Why is Port Forwarding Important?

Port forwarding helps make services inside your private network accessible from the outside world. For example, if you're running a web server or a game server on a device in your home or office network, port forwarding allows external users to connect to it without directly exposing the entire network.
