A demand-dial network can be created by placing Network Access Servers or NASs (which are servers placed on the perimeter of a network to serve as a gate?
way to some other network) configured as FEPs (or LACs) at geographic locations around the country or around the world. Client computers can make a dial-up
connection to the most convenient NAS, and they can send data anywhere to any of the organization’s locations that are reachable through the network. All communications will be tunneled and encrypted from endpoint to endpoint, and all communications will be tunneled to the requested location. Figure 7-8 represents such a network.
Tunnel Facts
