Network, address and ports
Where to find the server address, which ports are allocated and why you shouldn't change the port in a config by hand.
Address
The address and main port are on the "Console" tab and in the "Network" section. Players connect with it: IP:port.
Additional ports
Many games need extra ports: query (server list), RCON (remote console), SourceTV (CS2 broadcasting), the Steam port. They are already allocated and filled into the startup parameters; you can find them in the "Network" section.
Need another port (for example, for a web-map plugin or voice chat)? Contact support and we will add one.
Why you can't change the port in files
Only the ports allocated to your server are forwarded to the outside. If you set a different port in server.properties, serverDZ.cfg or another config, the server either won't start ("Address already in use") or won't be reachable from outside. The port is set by the panel: in the config keep the one shown in "Network".
The server isn't in the list, but joining by IP works
This is normal for many games: the Steam server list updates with a delay of up to 15–30 minutes and depends on the query port. Connect directly by IP and port.
