NETWORK ADMINISTRATION: VPN SERVERS AND CLIENTS
A VPN connection requires a VPN Server and a VPN Client — the server is the gatekeeper at one end of the tunnel, the client at the other. The main difference between the server and the client is that it’s the client that initiates the connection with the server. A VPN client can establish a connection with just one server at a time. However, a server can accept connections from many clients.
Typically, the VPN server is a separate hardware device, most often a security appliance such as a Cisco ASA security appliance. VPN servers can also be implemented in software. For example, Windows Server 2008 includes built-in VPN capabilities, though they are not easy to configure. And a VPN server can be implemented in Linux as well.
The following illustration shows one of the many VPN configuration screens for a Cisco ASA appliance. This screen provides the configuration details for an IPSec VPN connection. The most important item of information on this screen is the Pre-Shared Key, which is used to encrypt the data sent over the VPN. The client will need to provide the identical key in order to participate in the VPN
