5.3.2 Port Triggering
Some applications require that specific ports in the Router's firewall be opened for
access by the remote parties. 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 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”. A maximum 32 entries can be configured.
