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.”
