Disclaimer: I’m the author of Eztables.
Eztables allows you to quickly configure a firewall without ever touching iptables. The firewall rule syntax is designed to be easy to read and to apply. A tool like UFW was made with a similar mindset, but it is more host-centric. It was never designed to be used as a general-purpose firewall script.
Eztables on the other hand, can be used on any Linux box, wether it’s a desktop, (virtual) server or network firewall.
