NAME

Gufw - Graphic user interface for managing ufw

DESCRIPTION

Gufw is an easy to use firewall, powered by ufw (which is an easy to use firewall itself). ufw is stands for Uncomplicated Firewall, and is program for managing a netfilter firewall. It provides a command line interface and aims to be uncomplicated and easy to use. Gufw is here to provide a GUI for the ufw, so it can be even easier to use! iptables is already a very powerful tool by itself, but it's syntax can get awkward at times and hard to figure out, so Ubuntu developers decided to make ufw ("The reason ufw was developed is that we wanted to create a server-level firewalling utility that was a little bit more for `human beings`."), which was to be simpler. Now, on the graphical side of things, Firestarer already existed. But why not make an even easier to use GUI for desktop `human beings`, powered by ufw? This is where Gufw comes in. Once configured it will stay that way, so you don't need to be running Gufw on your desktop all the time!
