            Everything worked fine and smooth
            Hello!

            I've searched for a good firewall configuration script or similar for a while. This tool is the only one I've found that has everything I want:

            - Simple to understand, lots of configuration but not too much

            - Handles the most tipical situation (or at least the situation I have seen more in my experience): External zone (for clients), Internal Zone, Another external zone for servers, DMZ zone.

            - Last but not least: it works! And the traffic inside and outside is working too!

            Often, with other tools, after running the firewall I simply could not get any traffinc neither inside-out nor outside-in, not even auhorized traffic!

            Many thanks and congratulations to the author!
