Title: Not worth the price.
Review: Until now, all O'Reilly books I've encountered have been worth their weight in gold. Not this one! The very slim book focuses on simple tunneling systems (mostly from host to host) and cannot give sound advice or knowledge to any serious attempts at VPNs. Perhaps individual users with NTs might find some interest in the book, but for a network administrator its a total waste of money. Spend a few minutes browsing it and you've seen the best of it.
