Port Forwarding and Port Triggering
By default, the router blocks inbound traffic from the Internet to your computers except replies to your outbound traffic. You might need to create exceptions to this rule for these purposes:
•To allow remote computers on the Internet to access a server on your local network.
•To allow certain applications and games to work correctly when your router does not recognize their replies.
Your router provides two features for creating these exceptions: port forwarding and port triggering. The next sections provide background information to help you understand how port forwarding and port triggering work, and the differences between the two.
Remote Computer Access Basics
When a computer on your network needs to access a computer on the Internet, your computer sends your router a message containing the source and destination address and process information. Before forwarding your message to the remote computer, your router has to modify the source information and create and track the communication session so that replies can be routed back to your computer.
Here is an example of normal outbound traffic and the resulting inbound responses:
1.You open a browser and your operating system assigns port number 5678 to this browser session.
2.You type http://www.example.com into the URL field, and your computer creates a web page request message with the following address and port information. The request message is sent to your router.
Source address. Your computer’s IP address.
Source port number. 5678, which is the browser session.
Destination address. The IP address of www.example.com, which your computer finds by asking a DNS server.
Destination port number. 80, which is the standard port number for a web server process.
3.Your router creates an entry in its internal session table describing this communication session between your computer and the web server at www.example.com. Before sending
