Hexen II does not have the ability to send a heartbeat to a master server that can be queried with a game browser like GS3D or XQF. This webtool was created for you to register the WAN IP of your Hexen II server so users on the internet can join your server. Once you enter the IP address of your server it can be queried with GS3D or XQF.
The default port for Hexen II is 26900. The server list can be pulled @ http://hexenworld.org/hexen2
