How to use Game server ports checker?
Each game server listens on specific ports, over TCP and/or UDP. If one is blocked by the firewall, the router or the host's firewall, players can't connect or the server doesn't show in the browser. This tool gives the defaults and checks your list.
Pick your game in the list.
Note the required ports (including protocol) and the parameter that changes them.
Paste your opened ports (one rule per line, or the output of ufw status) to see what is missing.
Generate the rules with the “Firewall rules” tool, then also open the ports at your host and on your router.
