6. Interface Setup
The physical connections determine whether the router ports are local area network (LAN)
ports or wide area network (WAN) ports. There are two kinds of IP networks. The local, private
kind is the LAN network; the global, public kind is the WAN network. The following illustration
shows the relationship between the router and the two different networks.
A LAN is a shared communication system to which many computers are attached. A LAN is
generally limited to the immediate area, usually the same building or floor of a building.
A WAN is an outside connection to another network or to the Internet.
Click an Interface Setup link to set ATM VC values, ISP Encapsulation, configure multi-
connection settings, and LAN configuration.

already ran the Quick Start wizard, the information you provided to the wizard should be entered
into the fields already. After you finish the changes, click on the SAVE button to save your
