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 ZyXEL
device as a DHCP server or disable it. When configured as a server, the ZyXEL device
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 ZyXEL device 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
ZyXEL device 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

The ZyXEL device has built-in DHCP server capability that assigns IP addresses and DNS
servers to systems that support DHCP client capability.
