Chapter 11 NAT Forwarding
11. 2. Open Ports Dynamically by Port Triggering
Port Triggering can specify a triggering port and its corresponding external ports.
When a host in the local network initiates a connection to the triggering port, all the
external ports will be opened for subsequent connections. The router can record the
IP address of the host, when the data from the internet return to the external ports, the
router can forward them to the corresponding host. Port Triggering is mainly applied
to online games, VoIPs and video players, common applications include MSN Gaming
Zone, Dialpad and Quick Time 4 players, etc.
Follow the steps below to configure the Port Triggering rules:
1. Visit
http://tplinkwifi.net, and log in with the account you set for the router.
