DHCP

What DHCP Does

A 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 TW100-BRV204 can act as a

DHCP server

.

•

Windows 95/98/ME and 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 TW100-BRV204 '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 TW100-BRV204 's

DHCP Server

function.

•

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

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 TW100-BRV204 's, the following procedure is required.

1.

Disable the DHCP Server feature in the TW100-BRV204. This setting is on the LAN

screen.

2.

Configure the DHCP Server to provide the TW100-BRV204 's IP Address as the

Default

Gateway

.

To Configure your PCs to use DHCP

This is the default setting for TCP/IP under Windows 95/98/ME.

See

Chapter 4 - Client Configuration

for the procedure to check these settings.

Chapter 4

PC Configuration

This Chapter details the PC Configuration required on the local ("Internal")

LAN.

Overview

For each PC, the following may need to be configured:

•

TCP/IP network settings

•

Internet Access configuration

Windows Clients

This section describes how to configure Windows clients for Internet access via the TW100-

BRV204.

The first step is to check the PC's TCP/IP settings.

The TW100-BRV204 uses the TCP/IP network protocol for all functions, so it is essential that

the TCP/IP protocol be installed and configured on each PC.

TCP/IP Settings - Overview

If using the default TW100-BRV204 settings, and the default Windows

TCP/IP settings, no changes need to be made.

•

By default, the TW100-BRV204 will act as a DHCP Server, automatically providing a

suitable IP Address (and related information) to each PC when the PC boots.

•

For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP

client.

If using a Fixed (specified) IP address, the following changes are re-

quired:

•

The

Gateway

must be set to the IP address of the TW100-BRV204

•

The

DNS

should be set to the address provided by your ISP.
