What is a VPN?
Wireless-G VPN Broadband Router
Computer (using VPN client software that supports IPSec) to VPN Router
The following is an example of a computer-to-VPN Router VPN. (See Figure 2-3.) In her hotel room, a traveling
businesswoman dials up her ISP. Her notebook computer has VPN client software that is configured with her
office's VPN settings. She accesses the VPN client software that supports IPSec 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 connection to the central office's network, as if she were physically connected.
For additional information and instructions about creating your own VPN, please visit Linksys’s website at
www.linksys.com or refer to “Appendix C: Configuring IPSec between a Windows 2000 or XP PC and the VPN
Router.”
