5. 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.
