Firewalls have gained great fame recently as the ultimate in Internet Security. Like most things that gain fame, with that fame has come misunderstanding.
Any feedback is very welcome.
I am particularly looking for feedback from people who use Macintosh computers, as the information I have on them is scanty. I am human, and prone to making mistakes. If you find any, fixing them is of my highest interest. I will try to answer all e-mail, but I am busy, so don't get insulted if I don't. This document is meant as an introduction to how Firewalls and Proxy Servers work.
