EXCELLENT on what it's on, but it may not be on what you think.5
Make no mistake, this book is on what it says it's about "Attack Detection and Response with iptables, psad, and fwsnort" it contains very little information about setting up iptables to block unwanted external traffic.

HOWEVER setting up iptables (in the basic sense) doesn't require an entire book. Sure there are whole books on that topic but there is no need for a 300 page book on it, that just seems to be the size computer books have to be in order to get published. Which means other books on iptables are probably going to about 250 pages of fluff.

Incidentally this book actually only spends about the first 35 pages describing that, the remainder is fantastic, useful, well written information about doing the things that make iptables truly useful. "detection and response" ACTIVELY securing your system.

In addition to being comprehensive and useful this book happens to be well written, far better than most technical books.

If you're thinking about buying a book on Linux firewalls, make it this one, but if you're not already familiar with iptables expect to read the first 35 pages, then a couple online tutorials and then come back to this book.

The result is a fine pick for any programmer's library.5
Libraries catering to system administrators will find LINUX FIREWALLS an essential acquisition, discussing the technical aspects of the iptables firewall and Netfilter built into the Linux application. Examples of firewall log analysis, policies, network authorization processes and more compliment chapters that include Perl and C code pieces to help keep a network secure. The result is a fine pick for any programmer's library.

One of the best technical books published in 20075
Disclaimer: I wrote the foreword for this book, so obviously I am biased. However, I am not financially compensated for this book's success.

In the foreword I note that Linux Firewalls is a "great book." As a FreeBSD user, Linux Firewalls is good enough to make me consider using Linux in certain circumstances! Mike's book is exceptionally clear, organized, concise, and actionable. You should be able to read it and implement everything you find by following his examples. You will not only learn tools and techniques, but you will be able to appreciate Mike's keen defensive insights.

The majority of the world's digital security professionals focus on defense, because offense is left to the bad guys, police, and military. I welcome books like Linux Firewalls that bring real defensive tools and techniques to the masses in a form that can be digested and deployed for minimum cost and effort.

One of the main reasons Linux Firewalls is a great book is that Mike Rash is an excellent writer. I've read (or tried to read) plenty of books that seemed to offer helpful content, but the author had no clue how to deliver that content in a readable manner. Linux Firewalls makes learning network security an enjoyable experience. Mike is exceptionally detail-oriented (see the RST vs RST ACK issue on p 63 and elsewhere) and he often cites sources and additional references. Linux Firewalls very nicely integrates sample network traffic to make numerous points; Ch 11 has several great examples. The sections on Fwsnort even improved my understanding of Snort itself.

The bottom line is that if you are a user of non-Microsoft operating systems (Linux, BSD, etc.) and you want to know how Linux can help defend your network, you will enjoy reading Linux Firewalls.
