Part I, “VPNs,” introduces the topic of VPNs and discusses today’s main technologies, including IPsec. With copious configuration examples and troubleshooting scenarios, it offers clear information on VPN implementation designs.


The Complete Cisco VPN Configuration Guide contains detailed explanations of all Cisco® VPN products, describing how to set up IPsec and Secure Sockets Layer (SSL) connections on any type of Cisco device, including concentrators, clients, routers, or Cisco PIX® and Cisco ASA security appliances. As Cisco Systems® integrates security and access features into routers, firewalls, clients, and concentrators, its solutions become ever more accessible to companies with networks of all sizes. With increased use of Internet connectivity and less reliance on private WAN networks, virtual private networks (VPNs) provide a much-needed secure method of transferring critical information.
