CHAPTER 4

Basic

4.1 Overview

This chapter describes the screen you use to enable and configure your DHCP

server.

4.1.1 What You Can Do in This Chapter

The DHCP screen allows you to configure DHCP and IP address settings on the

LAN (Section 4.2 on page 44).

4.1.2 What You Need to Know

The following terms and concepts may help as you read through this chapter.

IP Address

A static IP is a fixed IP that you configure on the ZyXEL Device. A dynamic IP is

not fixed; a DHCP server provides an IP address to an Ethernet device each time it

connects to the network. When an Ethernet device is configured to obtain a

dynamic IP address from a DHCP server, it is known as a DHCP client.

DHCP

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 on the LAN. When

configured as a server, the ZyXEL Device provides the TCP/IP configuration for the

DHCP clients. If DHCP service is disabled, you must have another DHCP server on

your LAN, or else the computers must be manually configured.

IP Pool Setup

You can configure the starting IP address that the ZyXEL Device assigns to clients

as well as limit the number of devices which can obtain an IP address from the

ZyXEL Device.
