Port Triggering: Open Ports Dynamically
Port Triggering can specify a triggering port and its corresponding external ports. When a host on 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, video players and common applications including MSN Gaming Zone, Dialpad and Quick Time 4 players, etc.
Follow the steps below to configure the Port Triggering rules. Here we take TP-Link Router as an example.
- Visit http://tplinkwifi.net, and log in with your TP-Link ID or the password you set for the router.
- Go to Advanced > NAT Forwarding > Port Triggering and click Add.
- Click View Existing Applications, and select the desired application. The Triggering Port, External Port and Protocol will be automatically filled in. The following picture takes application MSN Gaming Zone as an example.
- Click OK.
- You can add multiple port triggering rules according to your network need.
- The triggering ports cannot be overlapped.
- If the application you need is not listed in the Existing Applications list, please enter the parameters manually. You should verify the external ports the application uses first and enter them into External Port field according to the format the page displays.
