Application Example: Port Triggering for Internet Relay
Chat
Some application servers, such as FTP and IRC servers, send replies to multiple port
numbers. Using port triggering, you can tell the router to open more incoming ports when a
particular outgoing port starts a session.
An example is Internet Relay Chat (IRC). Your computer connects to an IRC server at
destination port 6667. The IRC server not only responds to your originating source port, but
also sends an "identify" message to your computer on port 113. Using port triggering, you can
tell the router, "When you initiate a session with destination port 6667, you must also allow
incoming traffic on port 113 to reach the originating computer." The following sequence
shows the effects of the port triggering rule you have defined:
1. You open an IRC client program to start a chat session on your computer.
