3.7 LANs & 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.
3.7.1 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 as shown
next.
LAN
The interface to the
LAN is Ethernet.
The interface to the
