Port triggering is a configuration option on a NAT-enabled router that allows a host machine to dynamically and automatically forward a specific port back to itself. ''Port triggering'' opens an incoming port when the user's computer is using a specified ''outgoing port'' for specific traffic. == Description ==
Port triggering is a way to automate port forwarding in which outbound traffic on predetermined ports ('triggering ports') causes inbound traffic to specific incoming ports to be dynamically forwarded to the initiating host, while the outbound ports are in use. This allows computers behind a NAT-enabled router on a local network to provide services that would normally require the computer to have a fixed address on the local network. Port triggering ''triggers'' can open an incoming port when a client on the local network makes an outgoing connection on a predetermined port or range of ports.
