Port Forwarding for the A-Link Roadrunner 44B


What is Port Forwarding?
What is Port Triggering?




 

To setup port forwarding on this router your computer needs to have a static ip address. Take a look at our Static IP Address guide to setup a static ip address. When you are finished setting up a static ip address, please come back to this page and enter the ip address you setup in the Static IP Address box below.

Do not skip this step!




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 10.0.0.2.




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




Click the Virtual Server link near the left side of the page.




Enter the port to forward into the Public Port and the Private Port boxes. Select the protocol type using the Port Type radio button. If you need both TCP and UDP, create a duplicate configuration. The first configuration would have TCP selected, while the second one would have UDP selected. Enter the ip address to forward these ports to into the Host IP Address box. If you are forwarding ports so you can run a program on your computer, you should enter your computer's ip address into that box. Click the Add This Setting button.

Most people will never need to use this, but I'm going to explain why they have Public Port and Private Port here. The Public Port and Private Port entries are actually rather useful. They are there so you can direct traffic at two computers on your network. Let's say that you have two computers running Ftp servers on your network. Let's call these computers computer one(192.168.2.10) and computer two(192.168.2.11). Let's also say both these ftp servers are running on port 21. Okay we setup your router to forward port 21 to computer one(192.168.2.10:21). So every external ip address request from ftp goes two computer one. How do we get to the second computer? Well the Public Port and Private Port entries allow us to specify another outside port to connect to our internal port 21. Lets make the additional port, port 30. We would now setup a rule in the router with the Public Port set to 30 and the Private port set to 21. The ip address in that rule would be 192.168.2.11. So when you wanted to ftp to computer two you would specify port 30 in your ftp client. The router would see these requests coming in on port 30 and forward them to (192.168.2.11:21). This would allow you to ftp to both computers.

When you're finished, click Save Settings near the left side of the screen to save your changes.

And that's it! You're done!
