Smoothwall Linux Question Please Help!?

Question

OK i heard with smoothwall, it will take your HD and totally form it into a firewall, but all i need is something that runs in the background nothing big for my ubuntu but just something simple for protection.

Answer 1

Squid works good in Ubuntu.
there are others, they can be found in the Synaptic Package Manager, but as always, 2 firewalls will conflict. Learn the Iptables and how to use them, a firewall really isn't needed if iptables is set up.

Answer 2

Look here bunch of linux software ,firewalls too
