This page is meant to serve as a reference for configuring a firewall when setting up a server for network games. I got tired of scouring the web for this information every time I wanted to host a game, so I decided to write it all down in one spot. All configurations listed are for inbound traffic, as it is assumed that all outbound traffic is allowed. I've also erred on the side of listing too many ports if there are various conflicting sources. This page will be infrequently maintained, so your mileage may vary.
