Virtual Private Networks For Dummies

Intermediate Level Users.

With 2.8 million companies doing business over the Internet, Virtual Private Networks (VPNs) have become the next major technology. This book explains this complex technology in plain English, and addresses the two most pressing concerns of doing business over the Internet: security and speed. VPNs offer the solution to both these concerns through IP tunnelling. A tunnel is a virtual point-to-point connection made through the Internet. Once connected, users at each end of the tunnel can exchange information and access servers and services.

This book provides in-depth information on this process, as well as configuring routers; NT servers and VPN servers; firewalls, encryption; and troubleshooting.
