CHAPTER 6
The LAN Configuration Screens
6.1 Overview
Use the ADVANCED > LAN Configuration screens to set up the WiMAX Modem on the
LAN. You can configure its IP address and subnet mask, DHCP services, and other subnets.
You can also control how the WiMAX Modem sends routing information using RIP.
A Local Area Network (LAN) is a shared communication system to which many computers
are attached. A LAN is usually a computer network limited to the immediate area, such as the
same building or floor of a building.
6.1.1 What You Can Do in This Chapter
•The DHCP Setup screen (
Section 6.2 on page 60) lets you enable, disable, and configure
the DHCP server in the WiMAX Modem.
•The Static DHCP screen (
Section 6.3 on page 61) lets you assign specific IP addresses to
specific computers on the LAN.
•The IP Alias screen (
Section 6.4 on page 62) lets you add subnets on the LAN port. You
can also control what routing information is sent and received by each subnet.
•The IP Static Route screen (
Section 6.5 on page 64) lets you examine the static routes
configured in the WiMAX Modem.
•The Other Settings screen (
Section 6.6 on page 66) lets you control the routing
information that is sent and received by each subnet assign specific IP addresses to
specific computers on the LAN.
6.1.2 What You Need to Know
The following terms and concepts may help as you read through this chapter.
IP Address
IP addresses identify individual devices on a network. Every networking device (including
computers, servers, routers, printers, etc.) needs an IP address to communicate across the
network. These networking devices are also known as hosts.
Subnet Masks
Subnet masks determine the maximum number of possible hosts on a network. You can also
use subnet masks to divide one network into multiple sub-networks.
