6.4.4.2 Port Triggering
Some applications require that specific ports in the IG7600's firewall opened for access
by the remote parties. Port Triggering 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 "Trigger Ports". IG7600 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. (Figure 6-14,Figure 6-15)
