VIRTUAL PRIVATE NETWORK
A Virtual Private Network (VPN) connects the components and resources of
one network with another network in a secure way. (A network can consist
of even only one computer.) VPNs accomplish this by allowing the user
to tunnel through the Internet, or another network in a manner that lets
the tunnel participants enjoy the same security and features formerly available
only in private networks.
VPNs allow remote users to connect in a secure fashion to a server located
in a Local Area Network (LAN) using the routing infrastructure provided by
a public network (such as the Internet). From the user's perspective, the
VPN is a point-to-point connection between the user's computer and a host
server. The nature of the intermediate inter-network is irrelevant to the
user because it appears as if the data is being sent over a dedicated private
link. The secure connection across the inter-network appears to the user
as a private network communication -- hence the name Virtual Private
Network.
HOW TO SETUP AS A VIRTUAL PRIVATE NETWORK
CLIENT
PRE-REQUISITES
The client computer
must be running Windows NT4.0, Windows 95 or
Windows 98 with a
connection to the Internet already established, either by dialing up or having
a permanent connection through an internet service provider (ISP).
Once the internet connection has been made the VPN dialup network connection
can then be used to dial the IP address of the host server to establish a
"virtual private network" connection using the correct user id and
password.
