Chapter 17. NETWORKING ON THE RUN > Working with Virtual Private Networks

Working with Virtual Private Networks

Another possibility for remote connections to the company network involves the use of a Virtual Private Network (VPN) A VPN is a secure, dedicated, point-to-point connection over a public IP internetwork, such as the Internet. Using a VPN means that you don't have to configure the RAS server with a modem pool or other WAN connection type. The RAS server just needs to be connected to the Internet, and the remote client will connect to the company network by tunneling through the Internet.

Note

A VPN can also be used to create a connection between a branch office and the main corporate office. As long as the branch office can connect to the Internet, data can be securely routed over a VPN tunnel to and from the corporate network. This can actually be a cost-saving measure because a dedicated line, such as a leased phone line or some other WAN connection, doesn't have to be maintained between the branch and main offices.
