Router Mode Port Triggering

Port Triggering is an advanced feature that can be used to easily enable gaming and other internet
applications. Port Forwarding is typically used to enable similar functionality, but it is static and
has some limitations.
Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time
communications such as instant messaging, or remote assistance (a feature in Windows XP), you
should also enable UPnP according to the instructions at "Router Mode Universal Plug and Play
(UPnP)" on page 7-33.
Port Triggering opens an incoming port temporarily and does not require the server on the Internet
to track your IP address if it is changed by DHCP, for example. Port Triggering monitors outbound
traffic. When the wireless range extender detects traffic on the specified outbound port, it
remembers the IP address of the computer that sent the data and triggers the incoming port.
Incoming traffic on the triggered port is then forwarded to the triggering computer.
Using the Port Triggering page, you can make local computers or servers available to the Internet
for different services (for example, FTP or HTTP), to play Internet games (like Quake III), or to
use Internet applications (like CUseeMe).
Port Forwarding is designed for FTP, Web Server or other server based services. Once port
forwarding is set up, requests from the Internet are forwarded to the proper server. On the contrary,
port triggering only allows request from Internet after a designated port is 'triggered'. Port
triggering applies to chat and Internet games.
