4.1 LAN and WAN Overview
This section provides information on LANs, WANs, TCP/IP parameters and configuring your prestige for
Internet access.
4.1.1 LANs and WANs
A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same
building or floor of a building. A WAN (Wide Area Network), on the other hand, is an outside connection
to another network or the Internet.
4.1.2 LANs, WANs and the Prestige
The actual physical connection determines whether the Prestige ports are LAN or WAN ports. There are
two separate IP networks: one inside the LAN network, the other outside. The WAN network is shown
