This tutorial will show you how to configure your router to be able to host Starcraft games. For this tutorial I used a D-Link Dl-524. While routers work very similarly, their menus and terms may vary greatly, and so you may need to look for different, but related terms when configuring your own router. 1. Open a web browser (Internet Explorer, Mozilla Firefox, Opera, etc.), and enter in the Internet Protocol address of your router into the web address (URL) bar. This is usually 192.168.0.1, as seen in the example, but it may vary depending on the brand and model of the router. You can find the default address of your router in its manual, at its homepage, or you can ask your network administrator. Enter the number, then press enter. 2. Here the router asks you to identify yourself to be able to log in. The default username (first line) for my router is admin, with no password (second line) set, but settings may vary depending on router brand and model. You can find the username and password for your router in its manual, on its homepage, or by asking your network administrator. Once you have entered the appropriate things, press enter to go into the router. 3. Next up, look for port forwarding, tunnelling, or virtual server(s) in the menu. Note though that Starcraft needs multiple ports to be able to host for more than 2 clients, so you should choose the appropriate menu if you have single port forwarding and multiple port forwarding (here: application forwarding) separately, like in the example. 4. Once you have found the appropriate menu, enter in 6112 as trigger port (I used the range of 6112-6119 to be sure), and set the type to both TCP and UDP. Enter in these values for the public ports as well, as in the example, and name it with something that will remind you later on why the ports are open (example: Starcraft, SC, Battle.net, Blizzard game). My router already had a Battle.net template, so I just edited and activated it (port forwarding is disabled by default). 5. Apply the settings. Most routers restart themselves to apply the settings – once you are returned to the menu, the settings have been applied and you are ready to duke it out via Battle.net.
