Automatic Linux Firewall Port Limitations

I’ve been loving the ease of use that AMP provides for hosting game servers but I have a VPS that sits straight on the internet and would like to know if more granular control of the automatic firewall management is possible.

For example, I’d love to have the game server ports automatically be opened but the SFTP/RCON ports I’d appreciate not being opened by default. Or being able to have port 8080 closed (and the other ADS ports) since the proxy is locally run and managed.

I’ve disabled the automatic opening of ports in general but if there’s config file settings I can change to make this more streamlined I’d appreciate it!
