My point was that a firewall is superfluous if a program can just ask firewalld to poke a hole in the firewall for it automatically, because a program can already ask the system to open a listening port for it using bind(2) (and listen(2) and accept(2)) when no firewall is present. It means that in a world where automatic-hole-punching exists, the only use of a firewall on the host is maybe to limit the SCOPE of such communication, not whether such communication is allowed at all or not. This is where firewall zones come in. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
