CHAPTER 10

DHCP Server

10.1 Overview

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 NBG4115’s LAN as a DHCP server or disable it. When configured as a
server, the NBG4115 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.
10.1.1 What You Can Do in this Chapter
•Use the General (Section 10.2 on page 120) screen to enable the DHCP server.
•Use the Advanced (Section 10.3 on page 121) screen to assign IP addresses on
the LAN to specific individual computers based on their MAC Addresses.
•Use the Client List (Section 10.4 on page 122) screen to view the current DHCP
client information.
10.1.2 What You Need To Know
The following terms and concepts may help as you read through this chapter.
MAC Addresses
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC
address is assigned at the factory and consists of six pairs of hexadecimal
characters, for example, 00:A0:C5:00:00:02. Find out the MAC addresses of your
network devices if you intend to add them to the DHCP Client List screen.
Refer to Section 4.5.7 on page 50 for information on IP Address and Subnet Mask.
Refer to the Section 4.5.8 on page 50 section for information on System DNS
Servers.
