Home Office
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
PC 1 RVS4000 VPN Router PC 2
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 D:

The following is an example of a computer-to-VPN Router VPN. In her hotel room, a traveling businesswoman
dials up her ISP. Her notebook computer has the Linksys VPN client software, which is configured with her office's
IP address. She accesses the Linksys VPN client software and connects to the VPN Router at the central office. As
VPNs utilize the Internet, distance is not a factor. Using the VPN, the businesswoman now has a secure VPN Router

connection to the central office's network, as if she were physically connected.
