Choose “Advanced Setup→NAT→Port Triggering”, you can set Port Triggering on the screen

(shown in Figure 4-34).

Some applications require that specific ports in the Router's firewall should be opened for access

by remote devices. Port Trigger dynamically opens up the 'Open Ports' in the firewall when an

application on the LAN initiates a TCP/UDP connection to a remote device using the triggering

ports. The Router allows the remote party from the WAN side to establish new connections back to

the application on the LAN side using the open ports. A maximum 32 entries can be configured.
