Description

This book explains how to plan and build a Virtual Private Network (VPN), a collection of technologies that creates secure connections or "tunnels" over regular Internet lines. It discusses costs, configuration, and how to install and use VPN technologies that are available for Windows NT and Unix, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH). New features in the second edition include SSH and an expanded description of the IPSec standard.
Full Description

Historically, only large companies could afford secure networks, which they created from expensive leased lines. Smaller folks had to make do with the relatively untrusted Internet. Nowadays, even large companies have to go outside their private nets, because so many people telecommute or log in while they're on the road. How do you provide a low-cost, secure electronic network for your organization? The solution is a virtual private network: a collection of technologies that creates secure connections or "tunnels" over regular Internet lines--connections that can be easily used by anybody logging in from anywhere. A number of products now exist to help you develop that solution. This book tells you how to plan and build a VPN. It starts with general concerns like costs, configuration, and how a VPN fits in with other networking technologies like firewalls. It continues with detailed descriptions of how to install and use VPN technologies that are available for Windows NT and Unix, such as PPTP and L2TP, Altavista Tunnel, Cisco PIX, and the secure shell (SSH). New features in the second edition include SSH, which is a popular VPN solution for Unix systems, and an expanded description of the IPSec standard, for which several vendors have announced support. Topics include:

How the VPN compares to other available networking technologies
Introduction to encryption, firewalls, the IPSec standard, and other technologies that let VPNs work
Point to Point Tunneling Protocol (PPTP) and L2TP
The Altavista Tunnel
The Cisco PIX Firewall
Secure Shell (SSH)
Maintenance and troubleshooting

I suggets reading the reviews on amazon.com before buying this book.. it has a very low rating for a good reason. I bought this book on impulse based on oreilly's reputation, next time I'll check it out more thoroughly first.

I used the book to build an NT 4.0 Server running PPTP. I found 2 undocumented procedures that had to be done in order for a client to connect to the server via an ISP. Worked like a charm. The speed is there, the security, and getting rid of the 800# saved my company about $3000/month which will be reflected in my next pay raise request.

Regarding the 2 undocumented procedures: I have submitted a notice to O'Reilly about the changes and will wait for them to verify my changes and post them.

Best source to start with the Basic VPN technoligies.
I found this book very useful to get the feel of VPN
concepts.

This book gives good knowledge about the Altavista Tunnel,
and also explained about the Cisco PIX firewall and VPN tunnel
setup. But still needs a lot to cover.

I recommend this book for any one want to start with this new
emerging technology.

This book provides a good reference in VPN's. We used it to design and implement a VPN with our remote location and worked like a charm.

The only downside is that it could have provided more information regarding Microsoft's flaws in it's implementation of it's VPN technology. Otherwise it is a good book.

Media reviews "If you want to setup a VPN, you will find this book an excellent way to help you climb the learning curve." --Dustin Puryear, 32bits online, April 2000

"If you are considering implementing a VPN, you might well find this book to be an essential reference." --Dr. John R. Joyce, Scientific Computing and Automation, Oct 1998
