Would you mind updating the community wiki [1] to include this
information?  That way, web searching users and IRC users can also be
informed of such guidelines.  I'm envisioning an additional section in
the beginning that would allow one to use a firewall, yet stay
ignorant of what a firewall is or how it works.  Something like:

Most users don't need a firewall because linux based systems have
features blah blah blah.  But, in situations A, B, C, a firewall can
enhance security by making the computer invisible on the network.

To setup:
   sudo apt-get install ufw
   sudo ufw enable


And then maybe put the root issue with firestarter in the bottom
section.  Thanks!
