Configuring 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.
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 router 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, request from Internet will be forwarded to the proper server. On the contrary,
port triggering will only allow request from Internet after a designated port is 'triggered'. Port
triggering applies to chat and Internet games.
