DHCP

What DHCP Does

DHCP (Dynamic Host Configuration Protocol)

Server

allocates a valid IP address to a DHCP

Client

(PC or

device) upon request.

•

The client request is made when the client device starts up (boots).

•

The DHCP Server provides the

Gateway

and

DNS

addresses to the client, as well as allocating an IP

Address.

•

The WN-151ARM can act as a

DHCP server

•

Windows other non-Server versions of Windows will act as a DHCP

client

. This is the default

Windows setting for the TCP/IP network protocol. However, Windows uses the term

Obtain an IP

Address automatically

instead of "DHCP Client".

•

You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does

not have other Routers, this means there must only be one (1) DHCP Server on your LAN.)

Using the WN-151ARM's DHCP Server

This is the default setting. The DHCP Server settings are on the

LAN

screen. On this screen, you can:

•

Enable or Disable the WN-151ARM's

DHCP Server

function.

•

Set the range of IP Addresses allocated to PCs by the DHCP Server function.

Note: You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed

IP Addresses are NOT within the range used by the DHCP Server.

Using another DHCP Server

You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather

than the WN-151ARM's, the following procedure is required.

•

Disable the DHCP Server feature in the WN-151ARM. This setting is on the LAN screen.

•

Configure the DHCP Server to provide the WN-151ARM's IP Address as the

Default Gateway

To Configure your computer to use DHCP

This is the default setting for TCP/IP for all non-Server versions of Windows.

See

Chapter 4 - Client Configuration

for the procedure to check these settings.
