In this illustration, you see an example of a computer-to-VPN router VPN. In her
hotel room, a traveling businesswoman connects to her ISP. Her notebook
computer has the Cisco QuickVPN Client software, which is configured with her
office’s IP address. She accesses the Cisco QuickVPN Client software and
connects to the VPN router at the central office. As VPNs utilize the Internet,
distance is not a factor. While using the VPN, she now has a secure connection to
the central office’s network, as if she were physically connected.
