Port Forwarding and Port Triggering

Port forwarding and port triggering are advanced features that affect the behavior of

the firewall in your router. In the Port Forwarding / Port Triggering screen, 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
CU-SeeMe)
• 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.
• 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. Port triggering allows requests from the Internet only after a
designated port is triggered. Port triggering applies to chat and Internet games.

Port Forwarding

1. From the main menu, under the Advanced Heading, select Port Forwarding/Port
Triggering. The following screen displays:

address

button. Fill in the fields in the Add Custom Service screen.
