GameConfig is an information resource for finding port numbers to setup online games (configuring routers and such like).
Again the site was created with SEO in mind. People would be searching for the game they would be setting up combined with terms such as 'TCP ports', 'UDP ports', 'online setup', 'router setup', 'network ports' etc. We recently improved the site further by having a redesign, producing cleaner HTML.
