Which TCP/UDP port(s) should I open in my firewall to make my crossfire server fully accessable for anyone on the Internet?
Crossfire needs port 13327 open (incoming)
Metaserver needs port 13326 open (outgoing)
Both ports are TCP traffic only
Port 13327 will allow clients to connect to a server, and port 13326 will allow the server to show up in the metaserver list. For getting your server shown on the metaserver list, check the "metaserver_notification" setting in the settings file.
