LAN Setup
This chapter describes how to configure LAN settings.
4.1 LAN Overview
A Local Area Network (LAN) is a shared communication system to which many computers
are attached. A LAN is a computer network limited to the immediate area, usually the same
building or floor of a building. The LAN screens can help you configure a LAN DHCP server
and manage IP addresses.
4.1.1 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 and the other outside the
WAN network as shown next.
Figure 23 LAN and WAN IP Addresses
4.1.2 DHCP Setup
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual
clients to obtain TCP/IP configuration at start-up from a server. You can configure the Prestige
as a DHCP server or disable it. When configured as a server, the Prestige provides the TCP/IP
configuration for the clients. If you turn DHCP service off, you must have another DHCP
server on your LAN, or else the computer must be manually configured.
