Port forwarding is used to allow external access from the internet on a non-standard port to an internal device.

Port forwarding lets a router take traffic from the Internet that arrives on a specific external port and send it to a chosen internal device and port. This enables external access to a service inside a private network, and you can use a non-standard external port—mapping it to the internal service's port if needed. For example, forward external port 8080 to 192.168.1.100:80 so someone on the Internet reaches the internal web server by going to your public IP with :8080. This is a common way to expose a device behind NAT using a non-default port. Just be sure to secure exposed endpoints with proper firewall rules and authentication, or consider a VPN for safer remote access.
