CONNECTING THE CLIENT TO THE SERVER
For the game client to find the server you will need a domain and to edit the DNS records for it.
Create a new A record pointing to the server e.g ucgoserver.mydomain.com -> 192.168.0.1
Create new SRV records for this A record telling the game client which TCP ports to use. You will need 4 SRV records: info server, login server, chat server, game server
Update the file gameclient.cfg with this info, similar to below:
DNSServer_IP = YOUR DNS SERVER (IP address or domain) InfoServer = infoserver.mydomain.com LoginServer = login.mydomain.com GameServer = game.mydomain.com CmsServer = chat.mydomain.com
