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 have a box running slackware running as a router/firewall with apache serving up a few files.
every machine behind the firewall can connect to the internet fine but the router/firewall itself doesnt want to connect to the web, ftp, irc etc, even though it does obviously have a internet connection as all the machines behind it can connect without a problem.
thinking it was a iptables issue i flushed the tables completly, although this hasnt helped.
i cant ping anything, and it fails to revolve hostnames, although i also know its not a dns problem as it uses the same dns server as machines on the lan behind it.
obviously i've restarted networking etc but am i stuck.
I'm no iptables expert, but it sounds like you need to add some iptable rules that grant your firewall access to services like web, dns ,etc.... Think of the problem you describe as - requests (packets) that originate from your firewall do not hit the FORWARD chain like those from your LAN.
