Planning Your Virtual Private Network (VPN)	3
What is a VPN?

VPN Router to VPN Router

An example of a VPN router-to-VPN router VPN would be as follows. At home, a telecommuter uses his VPN router for his always-on Internet connection. His router is configured with his office’s VPN settings. When he connects to his office’s router, the two routers create a VPN tunnel, encrypting and decrypting data. As VPNs utilize the Internet, distance is not a factor. Using the VPN, the telecommuter now has a secure connection to the central office’s network, as if he were physically connected. For more information, refer to Appendix C, “Configuring a Gateway- to-Gateway IPSec Tunnel.”
