This Quick Start provides basic instructions for connecting the ADSL Barricade to a computer or LAN and to the Internet.

•

Connecting the Hardware describes how to set up the hardware.

•

Configuring Your Computers describes how to configure Internet properties on your computer(s).

•

Configuring the ADSL Barricade shows you how to configure basic settings on the ADSL Barricade to get your LAN

connected to the Internet.

This Quick Start assumes that you have already established an ADSL service with your Internet service provider (ISP). These instructions provide a basic configuration that should be compatible with your home or small office network setup. Refer to the subsequent chapters for additional configuration instructions.

Connecting the Hardware

TART

You connect the device to the wall phone jack, the power outlet, and your computer or network.

Warning:

Before you begin, turn the power off for all devices. These include your computer(s), your LAN hub/ switch (if applicable), and the ADSL Barricade.

Quick Start

Wall Jack

To a hub: use crossover cable to uplink port or straight cable to standard port

Hub/switch (for local area network)

Networked Computers

ADSL Barricade

AC adapter

To a PC: use a cross-over cable

Stand-alone computer

Figure 1. Overview of Hardware Connections

Step 1. Connect the ADSL cable

Connect one end of the provided phone cable (RJ-11) to the port labeled ADSL on the Rear Panel of the device. Connect the other end to your wall phone jack.

You can attach a telephone line to the device. This is helpful when the ADSL line uses the only convenient wall phone jack. If desired, connect the telephone cable to the port labeled Phone

Warning:

Although you use the same type of cable, the ADSL and Phone ports are not interchangeable. Do not route the ADSL connection through the Phone port.

Note:

ADSL splitters/microfilters are included with some models.

Configuring Your Computers

Step 2. Connect the Ethernet cable

If you are connecting a LAN to the ADSL Barricade, attach one end of a provided Ethernet cable to a regular hub port and the other to the Ethernet port on the ADSL Barricade. If you are using the ADSL Barricade with a single computer and no hub, you must use an Ethernet cable to attach the PC directly to the device. The cable is wired differently than the cable you would use to connect to a hub.

Step 3. Attach the power connector

Connect the AC power adapter to the Power connector on the back of the device and plug in the adapter to a wall outlet or power strip.

Step 4. Power up your systems

Turn on and boot up your computer(s) and any LAN devices such as hubs or switches.

Configuring Your Computers

This section provides instructions for configuring settings on your computers to work with the ADSL Barricade

Before you begin

By default, the ADSL Barricade automatically assigns all required Internet settings to your PCs. You need only to configure the PCs to accept the information when it is assigned.

Note:

In some cases, you may want to assign Internet information manually to some or all of your computers rather than allow the ADSL Barricade to do so. See Assigning static Internet Information to your PCs on page 16 for instructions.

Quick Start

Assigning static Internet Information to your PCs

In some cases, you may want to assign Internet information to some or all of your PCs directly (often called statically), rather than allowing the ADSL Barricade to assign it. This option may be desirable (but not required) if:

•

You have obtained one or more public IP addresses that you want to associate with specific computers (for example,

if you are using a computer as a public web server).

•

You maintain different subnets on your LAN (subnets are described in IP Addresses, Network Masks, and Subnets).

Before you begin, be sure to have the following information on hand (or contact your ISP if you do not know it):

•

The IP address and subnet mask you will assign to each PC which will be assigned static IP information.

•

The IP address of the default gateway for your LAN. In most cases, this is the address assigned to the LAN port on the ADSL

Barricade. By default, the LAN port is assigned this IP address: [192.168.1.1.] (You can change this number, or another number c

an be assigned by your ISP.) See Configuring the LAN Ports

on page 33

for more information.

•

The IP address of your ISP's Domain Name System (DNS) server.

On each PC you will assign static information, follow the instructions on pages 11 through 16 specific to the IP protocol. Once it is installed, continue to follow the instructions for displaying each of the Internet Protocol (TCP/IP) properties. Instead of enabling dynamic assignment of the IP addresses for the computer, the DNS server, and the default gateway, click the radio buttons that enable you to enter the information manually.

Configuring the ADSL Barricade

Note:

Your PCs must have IP addresses that place them in the same subnet as the ADSL Barricade's LAN port. If you manually assign IP information to all your LAN PCs, you can follow the instructions in Configuring the

LAN Ports to change the LAN port IP address

accordingly.

Configuring the ADSL Barricade

This section provides you instructions on how to log into the program of the ADSL Barricade and how to configure basic settings for your Internet connection. Your ISP should provide you with the necessary information to complete this step.

Logging into the ADSL Barricade – Quick Configuration Page

The ADSL Barricade provides a preinstalled software program called Configuration Manager which enables you to configure operation of the device via your Web browser. The settings that you most likely need to change before using the device are grouped onto one single [Quick Configuration] page.

Default Router Settings

In addition to handling the DSL connection to your ISP, the ADSL Barricade can provide a variety of services to your network. The device is preconfigured with default settings for use with a typical home or small office network.

Table 4 lists some of the most important default settings; these and other features are fully described in the subsequent sections. If you are familiar with network configuration, review the settings in Table 4 and check whether they meet the needs of your network. Follow instructions and change them if necessary. If you are unfamiliar with these settings, try to use the device without modification, or contact your ISP for assistance.
