Linux Packet Filtering and iptables

Linux Packet Filtering and iptables
by Oskar Andreasson

Publisher: Linuxtopia 2005

Description:
This document was simply written to give everyone a good and simple primer at how to get started with iptables, but at the same time it was created to be as complete as possible. This document requires some previous knowledge about Linux/Unix, shell scripting, as well as how to compile your own kernel, and some simple knowledge about the kernel internals.
