Help :: CGA Dedicated Server Topics

The CGA Dedicated Server is an IPX and serial relay server as well as audio chat capabilities. It runs as a Windows service or a Linux daemon. If you have not already done so, click here to download and install the server.


  • Multiple servers can be configured to run at the same time.
  • Maximum number of connections can be configred per server. (Combined limit of 512)
  • Each server is queried by the CGA website so yourself and other players can use it when it is online.
  • Each server establishes "virtual" networks for each game or group of players using the same network ID passed to it. This allows for a large number of simultaneous connections and games on one server since the network packets for each game are only sent to the players in their respective networks.
  • Each server can be configured as an IPX or serial relay server.
  • Audio chat servers (up to 10) can be configured for use by the virtual game servers. Audio chat integrated using the TeamSpeak 3 SDK.

NOTE: You cannot connect to a CGA dedicated server directly from DOSBox. You MUST use the CGA Client. The CGA server expects an initial TCP connection to be made which DOSBox does not do. This is necessary to ensure proper connection state maintenance. The TCP connection is used to detect when a player has disconnected from the server and removes that connection from the UDP connection pool. If an attempt is made to connect to the dedicated server from DOSBox the server will log an error that looks like this:

UDP: Unable to synchronize connection for <ip> : <port>, [<host>]

What this means is that the UDP server was unable to synchronize to a previously established TCP connection and DOSBox will fail to connect to the server. This is working as designed.
