Series ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready

Chapter 1:Introduction

Thank you for choosing the Instant Broadband™ ADSL Gateway with Modem / Router / 4-

Port Switch / Wireless-Ready. This Gateway allows you to set up a network with your PCs

and share your Internet connection.

The Gateway does this by connecting to your ADSL line, and using the Gateway’s Ethernet

ports to connect your PCs; it’s like each PC is connected directly to the Internet. This way, you

have an Ethernet network where you have several PCs utilizing one Internet connection simul-

taneously. Plus, if you add a Linksys wireless PC Card, it can be used as an Access Point and

the Gateway can bridge your Ethernet network with your wireless PCs.

The PCs that you connect to the Gateway’s four LAN ports, when properly configured, cre-

ate a LAN, or Local Area Network. They are connected with an Ethernet cable plugged into

your computer’s Ethernet adapter at one end and into one of the Gateway's LAN ports (num-

bered from one to four) at the other end. The term “Ethernet” is used to refer to your network

accessories, such as cables and adapters, because Ethernet refers to the type of network that

you are setting up. Ethernet refers to the accessories that transfer computer data from 10Mbps

to 100Mbps (speeds used by network devices.)

The Gateway allows you to share your ADSL connection using a built-in ADSL modem, and

can plug directly into your ADSL-enabled wall jack (DSL service line). The PCs that are con-

nected to the Gateway share this connection.

The Linksys ADSL Gateway

with Modem / Router / 4-Port Switch / Wireless-Ready

Features

ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready

Think of the Gateway as a network device with two sides: the first side is made

up of your private Local Area Network (LAN) of PCs. The other, public side is

the Internet, or the Wide Area Network (WAN), outside of your home or office.

The Gateway’s firewall (NAT) protects your network of PCs so users on the

public, Internet side cannot “see” your PCs. This is how your LAN, or network,

remains private. The Gateway protects your network by inspecting the first

packet coming in through the WAN port before delivery to the final destination

on the LAN port. The Gateway inspects Internet port services like the web serv-

er, ftp server, or other Internet applications, and, if allowed, it will forward the

packet to the appropriate PC on the LAN side.

What’s an IP Address?

IP stands for Internet Protocol. Every device on an IP-based network, including

PCs, print servers, and routers, requires an IP address to identify its “location,”

or address, on the network. This applies to both the WAN and LAN connections.

There are two ways of assigning an IP address to your network devices.

Static IP Addresses

A static IP address is a fixed IP address that you assign manually to a PC or

other device on the network. Since a static IP address remains valid until you

disable it, static IP addressing ensures that the device assigned it will always

have that same IP address until you change it. Static IP addresses are com-

monly used with network devices such as server PCs or print servers.

When using the Gateway to share your ADSL Internet connection, contact your

ISP to find out if they have assigned a static IP address to your account. If so,

you will need that static IP address when configuring the Gateway. You can get

the information from your ISP.

IP Addresses

Note: Since the Gateway is a device that connects two networks, it

needs two IP addresses—one for the LAN side, and one for the WAN

side. In this User Guide, you’ll see references to the “WAN IP

address” and the “LAN IP address.”

Since the Gateway has firewall security (NAT), the only IP address that

can be seen from the Internet for your network is the Gateway’s WAN

IP address.

However, even this WAN IP address for the Gateway can be blocked,

so that the Gateway and network seem invisible to the Internet—see

the IP Filtering section in “Chapter 6: Using the Gateway’s Web-based

Utility.”

Simply put, a router is a network device that connects two networks together.

In this instance, the Gateway connects your Local Area Network (LAN), or

the group of PCs in your home or office, to the Wide Area Network (WAN),

that is, the Internet. The Gateway processes and regulates the data that travels

between these two networks.

An Introduction to LANs and WANs

ADSL Gateway with Modem / Router / 4-Port Switch / Wireless-Ready

This user guide covers the basic steps for setting up a network with a Gateway.

After going through the “Getting to Know the Gateway” chapter, most users

will only need to use the following chapters:

• Chapter 3: Connecting the Gateway

This chapter instructs you on how to connect the ADSL line to the Gateway

and connect the PC(s) to the Gateway.

• Chapter 4: Configuring the PCs

This chapter instructs you on how to configure your PC(s) for a DHCP con-

nection, if the network settings are not already set to DHCP.

• Chapter 5: Configuring the Gateway

This chapter explains how to configure the Gateway using your web browser

and the Gateway’s web-based utility. You will configure the Gateway using

the settings provided by your ISP.

When you’re finished with the basic steps, then you are ready to connect to the

Internet. After the PC(s) can access the Internet through the Gateway, you can

alter the Gateway’s settings further; for example, you can adjust security fea-

tures and other settings to enable online gaming, run Internet servers, config-

ure a wireless LAN (WPC11 required) and more!

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network,

such as PCs and print servers. These IP addresses are called “dynamic”

because they are only temporarily assigned to the PC or device. After a certain

time period, they expire and may change. If a PC logs onto the network (or the

Internet) and its dynamic IP address has expired, the DHCP server will assign

it a new dynamic IP address.

For ADSL users, many ISPs may require you to log on with a user name and

password to gain access to the Internet. This is a dedicated, high-speed con-

nection type called Point to Point Protocol over Ethernet (PPPoE). PPPoE is

similar to a dial-up connection, but PPPoE does not dial a phone number when

establishing a connection. PPPoE also will provide the Gateway with a dynam-

ic IP address to establish a connection to the Internet. Point to Point Protocol

over ATM, or PPPoA, is a similar login method also used for some ADSL con-

nections.

DHCP (Dynamic Host Configuration Protocol) Servers

DHCP frees you from having to assign IP addresses manually every time a new

user is added to your network. PCs and other network devices using dynamic

IP addressing are assigned a new IP address by a DHCP server. The PC or net-

work device obtaining an IP address is called the DHCP client. By default, the

Gateway’s WAN setting is DHCP client.

A DHCP server can either be a designated PC on the network or another net-

work device, such as the Gateway. By default, a DHCP server (LAN side) is

enabled on the Gateway. If you already have a DHCP server running on your

network, you must disable one of the two DHCP servers. If you run more than

one DHCP server on your network, you will experience network errors, such as

conflicting IP addresses. To disable DHCP on the Gateway, see the DHCP sec-

tion in “Chapter 6: Using the Gateway’s Web-based Utility.”

Note: Even if you assign a static IP address to a PC, other PCs can

still use DHCP’s dynamic IP addressing, as long as the static IP

address is not within the DHCP range of the LAN IP Address.

If the dynamic IP addressing fails to provide a dynamic IP address,

refer to “Appendix A: Troubleshooting.”

up. If this flashes or stays solid after the bootup phase, the

Gateway may be malfunctioning. See “Appendix A:

Troubleshooting” if you encounter this problem.

Link/Act Green. The Link/Act LED serves two purposes. If the LED

is continuously lit, the Gateway is successfully connected to

a device through the corresponding port (1, 2, 3 or 4). If the

LED is flickering, the Gateway is actively sending or receiv-

ing data over that port.

Full/Col Green. The Full/Col LED also serves two purposes. If this

LED is lit up continuously, the connection made through the

corresponding port is running in Full Duplex mode. If the

LED flickers, the connection is experiencing collisions.

Infrequent collisions are normal.

100 Green. The 100 LED lights up when a successful 100Mbps

connection is made through the corresponding port.

The Reset Button

Briefly pressing the Reset Button or rebooting the Gateway will refresh the

Gateway’s connections. If the Gateway locks up, simply press the Reset Button

or power it down for three to five seconds. Leaving the power off for too long

could result in the loss of network connections.

Pressing the Reset Button and holding it in for a few seconds will clear all of

the Gateway’s data and restore the factory defaults. This should be done only

if you are experiencing heavy routing problems, and only after you have

exhausted all of the other troubleshooting options. By resetting the Gateway,

you run the risk of creating conflicts between your PCs’ actual IP Addresses

and what the Gateway thinks their IP Addresses should be. You may be forced

to reboot each network PC.

Note: The ADSL Gateway (with optional WPC11) is configured by

default to work out of the box with all Linksys Wireless Adapters. If

you have changed the defaults on your Linksys Wireless Adapters, or

are using other wireless adapters, you must temporarily change your

wireless adapter settings to: (SSID = linksys) in order to initially

access the Gateway wirelessly. After you have accessed the Gateway

with the default settings, you can change the Gateway settings to coin-

cide with your Network settings and reset your adapters.

Note: A small device called a microfilter (not included) may be nec-

essary between each phone and wall jack to prevent interference.

Contact your ISP if you have any questions.

Note: If you have a Linksys wireless PC Card (WPC11), be sure to

fully insert it into the PC Card slot on the back of the Gateway before

turning on the power. You must have this card inserted in order to

use the Gateway's wireless features.

Chapter 4: Configuring the PCs

The instructions in this chapter will help you configure each of your comput-

ers to be able to communicate with the Gateway.

To do this, you need to configure your PC’s network settings to obtain an IP (or

TCP/IP) address automatically (called DHCP). Computers use IP addresses to

communicate with each other across a network or the Internet.

You will need to know which operating system your computer is running, such

as Windows 95, 98, Millennium, 2000, or XP. One way to find out which oper-

ating system you have is by clicking the Start button and then going to the

Settings option. Then click Control Panel, and then double-click the System

icon.

You may need to do this for each computer you are connecting to the Gateway.

The next few pages tell you, step by step, how to configure your network set-

tings based on the type of Windows operating system you are using.

If your operating system is not referenced here, refer to your operating system

documentation.

Once you've configured your computers, continue to “Chapter 5: Configuring

the Gateway.”

Chapter 5:Configuring the

Gateway

In this chapter, you will configure the Linksys ADSL Gateway to be able to

gain access to the Internet through your Internet Service Provider (ISP). You

will need the setup information provided by your ADSL ISP:

• Your ADSL line VPI and VCI

• Your ADSL encapsulation type and multiplexing

For PPPoA or PPPoE users, you also need these values from your ISP:

• Your username and password

For RFC 1483 users, you may need these values from your ISP:

• Your ADSL fixed Internet IP address

• Your Subnet Mask

• Your Default Gateway

• Your primary DNS IP address

The above information should have been provided by your ADSL ISP. If not, contact

your ISP and they will be able to supply you with the correct settings. The instructions

from your ISP tell you how to set up your PC for Internet access. Because you

are now using the Gateway to share Internet access among several computers,

you will use the setup information to configure the Gateway instead of your

PC. You only need to configure the Gateway once using the first computer you

set up.

A. RFC 1483 Bridged

This mode supports two types of WAN IP Addresses: Dynamic IP Address or

Static IP Address. Follow the directions for the type of WAN IP Address you

need to use.

Dynamic IP Address

If your ISP says that you are connecting through a dynamic IP address, fol-

low these steps:

1. Select Dynamic IP Address as the WAN IP Address.

2. Click the Apply and Continue buttons to save the settings.

1. Open your web browser. (It is all right if you get an error message at this

point. Continue following these directions.) Enter http://192.168.1.1 in the

web browser’s Address field. Press the Enter key.

2. An Enter Network Password window, shown in Figure 5-3, will appear

(Windows XP users will see a Connect to 192.168.1.1 window, shown in

Figure 5-4). Enter admin in lowercase letters in the User Name field, and

enter admin in lowercase letters in the Password field (admin is the default

user name and password). Then, click the OK button.

3. The Gateway configuration screen will appear with the Setup tab selected.

Based on the setup instructions from your ISP, you may need to provide the

following information.

Host Name and Domain Name These fields allow you to provide a host

name and domain name for the Gateway. These fields are usually left blank.

192.168.1.1 in the PC’s web browser address window, as shown in Figure 6-1.

Press the Enter key.

An Enter Network Password window, shown in Figure 6-2, will appear

(Windows XP users will see a Connect to 192.168.1.1 window, shown in Figure

6-3). Enter admin in lowercase letters in the User Name field, and enter admin

in lowercase letters in the Password field (admin is the default user name and

password). Then, click the OK button.

In the following sections, you’ll find brief descriptions of each web page in the

utility and each page’s key functions. More detailed explanations and instruc-

tions can be found by clicking each page’s Help button or on Linksys’s website

• Encapsulation The Gateway supports five encapsulation modes: RFC

1483 Bridged, RFC 1483 Routed, RFC 2364 PPPoA, RFC2516 PPPoE,

and Bridged Mode Only. These modes can be selected from the drop-down

menu next to the Encapsulation setting. Each Setup screen and available

features will differ depending on what kind of connection mode you select.

Each mode is described on the following pages.

• Multiplexing The Gateway supports both VC and LLC multiplexing. Your

ISP will provide the correct selection for this setting.

The Setup screen is the first screen you see when you access the web-based

utility. If you have already installed and set up the Gateway, you have already

seen this screen and properly configured each of the values.

• Host Name & Domain Name These fields allow you to supply a host and

domain name for the Gateway. Some ISPs require these names as identifi-

cation. You may have to check with your ISP to see if your broadband

Internet service has been configured with a host and domain name. In most

cases, leaving these fields blank will work.

• Firmware Version This entry shows the version and date of the firmware

you are using. Future versions of the Gateway’s firmware will be posted and

available for download on the Linksys website at www.linksys.com.

• Current Time The Gateway will try to reach an Internet timeserver and dis-

play the current time in this location. If a timesaver cannot be reached, this

will show the time elapsed since the Gateway was powered on.

• Time Zone Set your local time zone in this field. If your region participates

in Daylight Savings Time (DST), check the box next to Daylight Savings

Time.

• LAN IP Address and Subnet Mask The values for the Gateway’s IP

Address and Subnet Mask as seen on the internal LAN are shown here. The

default values are 192.168.1.1 for the Device IP Address and 255.255.255.0

for the Subnet Mask.

• Virtual Circuit ID These fields consist of two items: VPI (Virtual Path

Identifier) and VCI (Virtual Channel Identifier). Your ISP will provide the

correct settings for these fields.

VPI Enter the number provided by your ISP. The number will be in the

range of 0 to 255.

VCI Enter the number provided by your ISP. The number will be in the

range of 0 to 65535.

Note: After setup, you can test and see if the settings are correct by

successfully connecting to the Internet.
