NAME
Gufw - Graphic user interface for managing ufw
DESCRIPTION
Gufw is an easy way 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!
