Virtual Private Networks
Introduction
A Virtual Private Network (VPN) is the extension of a private network over a
shared or public network, such as the Internet. By using a VPN, you can
send data between two computers in a manner that emulates a point-to-
point (PPP) private link. Emulation of the point-to-point link is done by
encapsulating data with a header that provides routing information, which
allows the data to traverse the public network until it reaches its destination.
Emulation of the private link is accomplished by data encryption. The link in
which private data is encapsulated and encrypted is called a VPN
connection.
VPNs are used to connect remote access users to corporate resources
over the public Internet, while maintaining the privacy of a private LAN. To
use a VPN, the client(s) in your private LAN will need to have VPN software
installed and a VPN endpoint, such as your corporate office. The BG-2000
supports passing the VPN connection and does not require any additional
configuration.
