8.6.2 Port Triggering
Certain applications, such as WAN network games, video conferences, and network calls,
require multiple connections. Because of the firewall setting, these applications cannot
work on a simple NAT router. However, certain special applications enable the
applications to work on an NAT router. When an application sends a connection request
to a trigger port, the corresponding ports are open for later connection and service
provision.
Choose Network Application > Port Triggering and the Port Triggering page is displayed.
