Title: Incomplete
Review: If you want to implement Firewall1 using this book as your only reference you will fail. One example: Their discussion of NAT explains adding rules and the theory behind NAT, but it leaves one minor detail out; the local.arp file on NT and the arp command on Unix. If you go 'by the book', your NAT will fail every time. I got this book because it's the only book on the planet dedicated to Firewall1, but there is better information freely available on the web! I hope someone sees this as an opportunity, and creates a real reference for us that implement and maintain Firewall1.
