Open a web browser like internet explorer or Netscape.

Enter the ip address of your router in the address bar of your browser. In the picture above the address bar has http://www.google.com in it. Just replace all of that with the ip address of your router. By default the ip address should be set to 192.168.123.254.

You should see a box prompting you for your username and password. Enter your username and password now. By default the username is root, and the password is blank. Click the Ok button to log in to your router.

In the menu on the left hand side of your screen click the Forwarding Rules link. This should drop down a submenu under forwarding rules. In that new submenu click the Special Application link.

Let's take a quick look in the Popular Applications drop down box for the program you are trying to setup triggering for. Is the program you are looking for there? If it is click it to highlight it. Then use the ID box to select the id of a blank line in the table above. Click the Copy To button to copy the configuration to the line that you previously selected. Put a check into the Enable box, and then click the Apply button to save the configuration.

If you did not see the application you are trying to setup port triggering for, don't worry. We will create a new port triggering configuration. Enter the trigger port into the Trigger box. You can think of the trigger port as sort of a light switch for the incoming ports. When data is flowing on the trigger port, the incoming ports are on or forwarded. If there is no data on the trigger port the incoming ports are off or not forwarded. For port information check the Ports list page or the software manufacture's homepage. Enter the incoming ports into the Incoming Ports box. These ports can be entered in a range like 65,67,70, a list like 500-600, or a combination of both like 65,67,500-600. Put a check mark in the Enable checkbox. Click Apply when you are finished setting up port triggering configurations.

Click the Save button at the bottom of the page to save your settings.

That's it! You are done!
