LAN Settings
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 NR2101’s WLAN as a DHCP server
or disable it. When configured as a server, the NR2101 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
• Use the LAN Settings screen to enable the LAN DHCP server and view the current DHCP client
information (Section 10.2 on page 86).
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.
IP Pool Setup
The NR2101 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 NR2101 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.
10.2 DHCP Server General Settings
The NR2101 has built-in DHCP server capability that assigns IP addresses to systems that support DHCP
client capability. Use this screen to enable the DHCP server. Click WLAN SETTINGS and the following
screen displays.
