Chapter 5 LAN Screens

This chapter describes how to configure LAN settings.

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. 

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.

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.

Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter.

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

The LAN parameters of the ZyXEL device are preset in the factory with the following values:
