5. Your router performs Network Address Translation (NAT) on the source IP address, and
sends the reply through the Internet to the computer or wireless device that sent the web
page request.
Set Up Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
• An application uses port forwarding to more than one local computer (but not
simultaneously).
• An application opens incoming ports that are different from the outgoing port.
With port triggering, the router monitors traffic to the Internet from an outbound “trigger” port
that you specify. For outbound traffic from that port, the router saves the IP address of the
computer that sent the traf
fic. The router temporarily opens the incoming port or ports that
you specify in your rule, and forwards that incoming traffic to that destination.
Port forwarding creates a static mapping of a port number or range of ports to a single local
computer. Port triggering can dynamically open ports to any computer when needed and
close the ports when they are no longer needed.
Note: If you enabled port triggering because you use applications such as
multiplayer gaming, peer-to-peer connections, real-time
communications such as instant messaging, or remote assistance (a
feature in Windows XP), enable Universal Plug and Play (UPnP). See
Improve Network Connections with Universal Plug and Play on
page 41.
