Server Administration Guide
Setting up a server for Armagetron Advanced isn't terribly difficult, but there are a few things you need to consider when you do it. Taking a few minutes to figure out what you're trying to do will save you a whole lot of headache/heartache later on when people start playing your server.
Private or Public?
The setting TALK_TO_MASTER is off by default. To make your server public (available on the master server list), you must turn on this setting. If it is off, players will only be able to connect to your server through the Server Bookmarks using your IP address.
