Because there is no single virtual private network (VPN) solution, it's critical to have a planning framework to ensure successful deployment. A VPN is virtual in that it has no corresponding physical network but rather shares physical circuits with other traffic. A VPN is private in that it isolates Internet traffic with routing and secures if with encryption. The use of “private” and “Internet based“ to describe the same service appears to be an oxymoron, but we explain how VPNs manage to be both. Many choices will confront you in considering how to deploy a VPN. We briefly describe the core choices such as the different types of VPNs, encryption, firewalls, and how to accommodate legacy systems.
