LAN Screens
This chapter describes how to configure LAN settings.
5.1 LAN Overview
Local Area Network (LAN) is a shared communication system to which many computers are attached. The
LAN screens can help you configure a LAN DHCP server, manage IP addresses, and partition your physical
network into logical networks.
Please see the Wizard Setup chapter for the background information about Primary and Secondary DNS
Server and IP Address and Subnet Mask.
5.2 LANs and WANs
A LAN 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.
5.2.1 LANs, WANs and the ZyAIR
The actual physical connection determines whether the ZyAIR 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:
