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.

Now that I have configured my firewall, how do I watch it run?
Is there some sort of tool(s) or log(s) that will show arriving and departing packets movement through the various queues. It would be nice to watch in real-time, but run-log-view batches are good too.

iptraf is your friend.
Try it, you can filter for card(s) port(s) and whatever you want.
For that, you can use packet counters, and no tool is necessary. Bit primitive though, depending on how your firewall ruleset is structured, and okcomputer44's suggestion is probably better, unless you intend to leave monitoring in place, long term. Then, the low overhead of packet counting might be valuable
