How to use Custom port firewall rules?

Opening the right ports is what separates a local server from a reachable one. This tool is game-independent: you supply the ports from your server's documentation, it writes the commands. It stands in for the lack of documented official ports for Open//77.

  1. Pick the target: Linux ufw, Linux iptables or Windows netsh.

  2. Enter one port per line with its protocol: 7777/udp, 8000-8010/tcp or 7777/both.

  3. If needed, restrict access to an IP address (for instance for an admin interface).

  4. Run the commands as administrator or with sudo, then test from an outside network.
