This chapter describes how to configure LAN settings.

9.1 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,
manage IP addresses, and partition your physical network into logical networks.

9.1.1 IP Pool Setup

The NBG420N 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 NBG420N itself) in
the lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers
for mail, FTP, TFTP, web, etc., that you may have.

9.1.2 System DNS Servers

Refer to the IP address and subnet mask section in the Connection Wizard chapter.

9.2 LAN TCP/IP

The NBG420N has built-in DHCP server capability that assigns IP addresses and DNS servers
to systems that support DHCP client capability.

9.2.1 Factory LAN Defaults

The LAN parameters of the NBG420N are preset in the factory with the following values:
• IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits)
• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If your ISP gives you explicit
DNS server address(es), read the embedded web configurator help regarding what fields need
to be configured.
