Building VPNs Book

Virtual Private Networks (VPNs) are a cheap and secure way for companies to transmit information over the Internet. With implementation of two new protocols, IPSec and MPLS, VPNs are about to become standard operating procedure. This guide aims to teach network engineers and architects, internetworking pros in the enterprise and service provider organisations and security pros working on VPNs as a corporate security measure how to use them. It walks readers through a VPN build from the ground up and demonstrates how IPSec and MPLS can be used in conjunction.
