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.
5.2 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 ZyAIR
as a DHCP server or disable it. When configured as a server, the ZyAIR provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server
on your LAN, or else the computer must be manually configured.
5.2.1 IP Pool Setup
The ZyAIR is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the ZyAIR itself) in the
lower range for other server computers, for instance, servers for mail, FTP, TFTP, web, etc.,
that you may have.
5.2.2 System DNS Servers
Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter.
5.3 LAN TCP/IP
