Firewalling Tiger (I)

I have spent a few hours testing an increased security version of the built-in's firewall. Tiger's firewall is the famous ipfw, a free and very, very secure and stable firewall, built inside of the operating system kernel.
I'm very pleased with the results of the the firewall script, it is a very tight one, limiting not only what is allowed to connect to the Os X box, but also, what is actually allowed to go to the outside.
I'll keep testing it a little more, and then post it here.

I was a bit afraid, since I was doing exactly the same thing, editing the internal firewall, when my old & beloved iBook died on me.
