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.

Don't think I wan't to use a prebuilt script was kinda looking forward to writing my own.
btw if I set all my policies to DROP shouldn't I be able to allow browsing? something like this (except this doesn't work)
iptables -P INPUT DROP
iptables -P OUTPUT DROP
iptables -P FORWARD DROP
# (know port 80 is for internal webserver, couldn't I change the
# port to ??? so browsing is allowed
# eth0 = external iface
# eth1 = internal iface (192.168.0.0/24)
