Before we can open ports for ABC, we need to figure out what ports ABC is using. Here is a brief walkthrough on how to do that. Go ahead and open up ABC.

Click File in the menu at the top of the program. Then click Preferences in the list that drops down.

In the menu on the left hand side of your screen, click the Network link. On this page you should see a Port box. You can change the port number that ABC is using if you like. The number that is in that Port box is the port that you will have to open.

Please enter the number that was in that box below.

To configure this router's firewalling properly you should setup a static ip address on your computer. 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.

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 10.1.1.1.

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

Click the Advanced button near the top of the page.

Click the Filters button near the left side of the page.

And that is it! You are done!
