I am human, and prone to making mistakes. If you find a fix for anything please send it to me. 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. I am not, nor do I pretend to be, a security expert.
