Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am in the process of implementing a Asterisk PBX in my office. Looking at it from the security perspective what would be the best location for it in my network. I have thought about placing it in front of my firewall and just enable routing on the box, harden it and then have my LAN network behind my firewall. I have had some people tell me that it is preferable to place it behind my firewall and place it in the a DMZ and use port forwarding. Security Gurus lets here it!
Yea you can place your asterisk box behind your firewall, but in that case you have to specify NAT proxy for the user dialing from outside... first your firewall should be viewable for users to protect ur server...
well this all wholly depends on what kind of architecture you have. i take it it's not a huge LAN, with only a few subnets, so your choices will presumably be limited somewhat. I can't see any good reason to put it infront of a firewall though... make your network level security deal with most of the attacks your'll get and just port forward i'd say.

well you should have a secure server network (or multiple) already, so yeah, but the logic of a "DMZ" often breaks down in a real environment. i woudl put it with any other internet facing servers, in a secure subnet protected from both the internet and other clients.
