Portforwarding
Port forwarding is a network technique that directs incoming traffic from one IP address and port number to another internal IP address and port. It is commonly implemented on routers performing network address translation (NAT) to allow external devices to reach services hosted on machines inside a private network. By mapping an external port to an internal host and port, a router forwards matching packets to the designated device.
Typical uses include hosting web or game servers, remote desktop access, voice-over-IP endpoints, security cameras, and
Configuration generally requires assigning a consistent internal IP to the target device, specifying the external port,
Security considerations are important: exposing internal services increases attack surface, so administrators should use strong authentication,
