Title: Very simple book and full of serious errors
Product review: I am sure that, I wouldn't have bought this book if someone had reviewed this book before me.Briefly, if you are looking for a deep information on several brand firewall's configuration and especially on VPN subject, belive, this book is not for you.The first half of the book is full of with just generic information which almost avery avarage IT people have. That is, whithin a few minutes you pass the first two part.Than you decide your point on this book while reading the VPN part. No detail on the issues, no real time application samples and most important one completely wrong several figures.For example, on page 247 figure 5.20 says "MPLS Packet Structure", but you see screen snapshot of Putty telnet application's configuration window. I honestly couldn't understand if they are joking or have another purpose.My only advice, always prefer the books you can look inside it.
