3.2.2 Port Triggering
Some applications require multiple connections, like Internet games, Video conferencing,
Internet telephony, etc. Because of the firewall function, these applications cannot work with a
pure NAT router. The Port Triggering feature allows some of these applications to work with
this product. If the mechanism of Port Triggering fails to make an application work, try setting
your computer as the DMZ host instead.

specified port numbers are allowed to pass through the firewall.
