VPN tunnel using IPSec (refer to “Appendix C: Configuring
IPSec between a Windows 2000 or XP PC and the Router”).
Other versions of Microsoft operating systems require
additional, third-party VPN client software applications
that support IPSec to be installed.
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 D: Configuring a
Gateway-to-Gateway IPSec Tunnel.”

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,
she now has a secure connection to the central office’s
network, as if she were physically connected.
