Summary: Look for a better book
Review: What was O'Reilly thinking!! This is the first time I wasted money on an O'Reilly book (and I have plenty). This book was a rush job. There are many inaccuracies, a lot seem to be the editors mistakes. The authors seem to have the practical experience, but it is not communicated in a clear manner. The chapters on PPTP, AltaVista and Cisco PIX were organized in a good way and were helpful. Overall, the diagrams are poor. Better graphics could have salvaged this book. I give it two stars because there are not that many books on the market.

Summary: Product information and updates
Review: With Virtual Private Networks, we present solutions to some of the most pressing issues in corporate networking today: the need to tie offices to each other and to remote staff cheaply and securely.New technologies, and new versions of existing products, are always coming on the market. As an adjunct to the book, the authors have created a Web site to list some basic facts about them.

Summary: A solid solutions-based book
Review: Wow. Someone is unhappy that O'Reilly publishes NT books. Though most of the solutions covered in the book did not apply to my company, it definitely presented the options in a clear, concise manner. We are investigating using a VPN for our NT/UNIX network, and the chapters on PPTP and the PIX were excellent. The overview chapters were helpful, though there could be more on software solutions other than the few presented.
