    Chapter 8: Virtual Private Networks 8. Virtual Private Networks One of the principal features of routers is their support of virtual private networks (VPNs). This document discusses transmission security, VPNs, and how the WRT4000 Series Cellular Wireless Router sets up and uses a VPN connection. A VPN is a secure encrypted transmission between two or more private endpoints over a public network.
