Vpn Preliminary Requirements

A  VPN stands for the Virtual Private Network, it is basically a computer network that is encrusted on top of an original computer network. The private nature of a VPN refers to the data travelling over this network is not usually visible to, or is summed up from, the principle network traffic. This is done with the help of powerful encryption, as VPN’s are most commonly set up to be high security “network tunnels”. Similarly, the traffic inside the VPN seems to the principle network as just another traffic flow to be passed. If you can visualize secured “pipe” inside the wire which is also your connection, you would easily picture how to set a VPN.

In more technical terminologies, the link layer protocols of the virtual private network are believed to be tunneled through the principle transport network.

The term VPN is used to describe various different network configurations and protocols. It can become difficult when trying to generalize about the characteristics of a

Virtual Private Network. VPN technologies can differ in the following ways:

1.    In the levels of security given.
2.    In the protocols which are used to tunnel the traffic over the principle network.
3.    Whether they offer remote access or site to site access connectivity.
4.    By the location of tunnel extinction, such as the network provider edge.
5.    By the OSI layer which is presented to the connecting network, like the Layer 2 circuits or Layer 3 network connectivity.

There some preliminary requirements of VPN that the VPN 1 secure remote client and the server PCs should follow in order to connect to the VPN using the AR Mini Key. They include the client hardware requirements such as standard USB port and AR Mini Key token. Client Software requirements such as operating systems: windows 98, ME, 2000 or XP, VPN 1 secure remote. And at last VPN secure remote server requirements like check point VPN 1 and Firewall 1.
