Port Triggering
Some applications require that specic ports in the gateway’s rewall be opened for access by remote parties. Port Trigger dy-
namically opens up the ‘Open Ports’ in the rewall when an application on the LAN initiates a TCP/UDP connection to a remote
party 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.
After selecting Advanced Setup -> NAT -> Port Triggering from the left navigation bar, click the Add button. Customize the elds
as needed for the rewall pinholes you wish to establish.
A maximum 96 entries can be congured.
