6.4.2 Port Triggering

Triggers are used to deal with application protocols that create separate sessions. Some
applications, such as NetMeeting, 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
Freeway DSL 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.
