Firewall

Firestarter is a GUI that configures iptables, it's pretty easy to
use. There is also fwbuilder but it looked a little more complex.
Configuring a firewall correctly from my experience is not quite as
easy on Linux as it is on Windows, especially with regards to writing
iptables rules manually. Infact I absolutely loath messing with
iptables rules, it's just a huge turn off considering the amount of
complexity that it has.
