Your router then sends this request message through the Internet to the web server at www.example.com.

4.The web server at www.example.com composes a return message with the requested web page data. The return message contains the following address and port information. The web server then sends this reply message to your router.

Source address. The IP address of www.example.com.

Source port number. 80, which is the standard port number for a web server process. Destination address. The public IP address of your router.

Destination port number. 33333.

5.Upon receiving the incoming message, your router checks its session table to determine whether an active session for port number 33333 exists. Finding an active session, the router then modifies the message to restore the original address information that is replaced by NAT. Your router sends this reply message to your computer, which displays the web page from www.example.com. The message now contains the following address and port information.

Source address. The IP address of www.example.com.

Source port number. 80, which is the standard port number for a web server process. Destination address. The IP address of your computer.

Destination port number. 5678, which is the browser session that made the initial request.

6.When you finish your browser session, your router eventually detects a period of inactivity in the communications. Your router then removes the session information from its session table, and incoming traffic is no longer accepted on port number 33333.

Port Triggering to Open Incoming Ports

In the preceding example, requests are sent to a remote computer by your router from a particular service port number, and replies from the remote computer to your router are directed to that port number. If the remote server sends a reply to a different port number, your router does not recognize it and discards it. However, some application servers (such as FTP and IRC servers) send replies to multiple port numbers. Using the port triggering function of your router, you can tell the router to open more incoming ports when a particular outgoing port originates 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 have to allow incoming traffic also on port 113 to reach the originating computer.” Using steps similar to the preceding example, 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.
