Notice to Users of the United States Telephone Network

The following notice applies to versions of the modem that have been FCC Part 68 approved.

This equipment complies with Part 68 of the FCC rules and the requirements adopted by the Administrative Council for

Terminal Attachment (ACTA). On the bottom side of this equipment is a label that contains, among other information, a

product identifier in the format US:AAAEQ##TXXXX. If requested, this number must be provided to the Telephone

Company.

This equipment is intended to connect to the Public Switched Telephone Network through a Universal Service Order

Code (USOC) type RJ11C jack. A plug and jack used to connect this equipment to the premises wiring and telephone

network must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA. A compliant

telephone cord and modular plug is provided with this product. It has been designed to be connected to a compatible

modular jack that is also compliant.

The Ringer Equivalence Number (or REN) is used to determine the number of devices that may be connected to a

telephone line. Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming

call. In most but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that

may be connected to a line, as determined by the total RENs, contact the local Telephone Company. The REN for this

product is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the

REN without a decimal point. For example, 03 represents a REN of 0.3.

If the modem causes harm to the telephone network, the Telephone Company will notify you in advance that temporary

discontinuance of service may be required. But if advance notice is not practical, the Telephone Company will notify the

customer as soon as possible. Also, you will be advised of your right to file a complaint with the FCC if you believe it is

necessary.

The Telephone Company may make changes in its facilities, equipment, operations or procedures that could affect the

operation of the equipment. If this happens, the Telephone Company will provide advance notice in order for you to

make necessary modifications to maintain uninterrupted service. If trouble is experienced with the modem, refer to the

repair and warranty information in this document.

If the equipment is causing harm to the telephone network, the Telephone Company may request that you disconnect

the equipment until the problem is resolved.

The user may make no repairs to the equipment.

Connection to party line service is subject to state tariffs. Contact the state public utility commission, public service

commission or corporation commission for information.

If the site has specially wired alarm equipment connected to the telephone line, ensure the installation of the modem

does not disable the alarm equipment. If you have questions about what will disable alarm equipment, consult your

Telephone Company or a qualified installer.

Introduction

Definitions

Before you install or use your new router, you may find it helpful to understand the

following terms:

A bridge is a device that forwards any message from one part of a network to

another.

A router is a device that forwards messages according to their network

addresses.

ADSL is Asymmetric Digital Subscriber Line, a version of DSL that allows a

higher speed for information coming from the Internet to your PC

(“downstream”) than it does for information going to the Internet from your PC

(“upstream”).

ReachDSL is a version of DSL that works on lines too long or too noisy for

ADSL.

ADSL/R is technology that combines ADSL and ReachDSL in one device.

The Model 6381 is a Digital Subscriber Line (DSL) modem that may be set by you

to run in bridge or router mode. Because it is most frequently used as a router, that

is how it is referred to in this manual. It supports ADSL/R.

Hardware Installation and

PC Setup

Overview

This chapter provides basic instructions for connecting the router to a computer or

a LAN and to the Internet using DSL. The first part provides instructions to set up

the hardware, and the second part describes how to prepare your PC for use with

the router. Refer to Chapter 3, Using the Web Interface for router configuration

instructions.

It is assumed that you have already subscribed to DSL service with your telephone

company or other Internet service provider (ISP).

Connecting the Hardware

Shut down your PC before connecting the router. To connect your router:

Procedure

1. Connect the supplied modular phone cable to the LINE port, and connect the

other end of the cable to your phone jack.

2. If you would like to use a phone in the vicinity of the router, connect it to the

PHONE jack of the router using the cord that came with your telephone. The

router has an internal POTS filter, so you do not need to install one here.

3. Connect the USB port, the LAN port, or both.

— If you are connecting the router directly to a PC (rather than to a LAN), you

can use either the USB port or the LAN port. (Do not connect both the

USB port and the LAN port to the same PC.)

To use the USB port, connect the supplied USB cable to the USB port of

the router, then connect the other end of the cable to a free USB port on

your PC.

When you start your PC (in a later step), Windows will detect the new

hardware and initiate the Found New Hardware Wizard. Follow the

instructions under Windows USB Driver Installation on page 2-3.

— Alternatively, you can use the included Ethernet cable to connect your

computer directly to the router. Attach one end of the supplied Ethernet

2. Hardware Installation and PC Setup

2-2 January 2005 6381-A2-GB23-10

cable to the LAN port and connect the other end to the 10/100BaseT port

on the network interface card in your PC.

— If your LAN has more than one computer, you can attach one end of an

Ethernet cable to a hub or a switch and the other to the port labeled LAN

on the router. This probably will require an Ethernet crossover cable. See

the documentation for your hub or switch to be sure.

4. Connect the cylindrical power plug into the POWER connector on the back of

the device. Next:

— If you have a wall-mount adapter, plug the AC adapter into a wall outlet or

a power strip.

— If you have a table-top adapter, use the AC power cord to connect the

adapter to a wall outlet or power strip.

The supplied power adapter may look different than the one illustrated here.

5. Turn on your PC any other LAN devices, such as hubs or switches.

Configuring Your PC

Before you start to access the router via Ethernet, you must configure your PC's

TCP/IP address to be 192.168.1.x, where x is any number between 2 and 254.

The subnet mask must be 255.255.255.0. Your router's default IP address is

192.168.1.1.

If you used the Ethernet cable to connect your router and PC, you do not need any

specific driver installation and you can skip Windows USB Driver Installation,

below. If you used the USB cable on a PC running a Windows operation system,

install the provided USB driver.

Windows 95 and Windows NT 4.0 do not support USB without additional software

(not included with your router). If USB driver installation fails under those operating

systems, contact your service provider.

Windows USB Driver Installation

As soon as you connect the USB cable between your PC and the router, Windows

will detect new hardware and the Found New Hardware Wizard will pop up. To

install the USB driver:

Procedure

1. Choose "Install from a list or specific location" and click on Next (Figure 2-2).

Figure 3-6. Setup Options

Wide Area Network Connection

The DSL connection is the Wide Area Network (WAN) connection. The

requirements for the WAN connection depend on your Internet Service Provider

(ISP).

Local Area Network Connection

On the other side of your router are your own Local Area Network (LAN)

connections. This is where you plug in your local computers to the router. The

router is normally configured to automatically provide all the PCs on your network

with Internet addresses.

If you connected a PC (rather than a hub or a switch) directly to the router, your

LAN consists of that PC.

Saving Changes

Note that the Apply button temporarily saves changes you make. To make

changes permanent, click on Tools (at the top of the page) and select System

Commands. At the System Commands page, click on Save All.

3. Using the Web Interface

3-6 January 2005 6381-A2-GB23-10

Configuring the WAN

Before the router will pass any data between the LAN interface and the WAN

interface, the WAN side of the router must be configured. Depending upon your

ISP, you will need some or all of the information listed below before you can

properly configure the WAN:

Your DSL line’s Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI)

Your DSL encapsulation type and multiplexing mode

Your DSL training mode (default is MMODE)

If you use PPPoA or PPPoE, you also need these values from your ISP:

Your username and password

If you use multiprotocol encapsulation over ATM Adaptation Layer 5 (as described

in RFC 1483), you may need these values from your ISP:

Your DSL fixed Internet IP address

Your subnet mask

Your default gateway IP address

Your primary DNS IP address

Since multiple users can use the router, the router can simultaneously support

multiple connection types. You must set up different profiles for each connection.

The router supports the following protocols:

DHCP

PPPoA (RFC 2364)

PPPoE (RFC 2516)

Static

Bridged

3. Using the Web Interface

6381-A2-GB23-10 January 2005 3-7

New Connection

A new connection is basically a virtual connection. Your router can support up to 8

different virtual connections. If you have multiple different virtual connections, you

may need to utilize the static and dynamic routing capabilities of the router to pass

data correctly.

PPPoE Connection Setup

PPPoE is defined in the Internet standard RFC 2516. It is a method of

encapsulating PPP packets over Ethernet. PPP (Point-to-Point Protocol) is a

method of establishing a network session between network hosts. It usually

provides a mechanism of authenticating users.

To configure the router for PPPoE:

Procedure

1. Click on Setup and then click on New Connection. The default PPPoE

connection setup is displayed.

2. At the Type field, select PPPoE and the PPPoE Connection Setup page is

displayed.

3. Give your PPPoE connection a unique name. The name must not have spaces

and cannot begin with numbers.

4. Select a PVC Sharing type of Disable, Enable, or VLAN.

5. Select or enter a VPI and VCI (as supplied by your DSL service provider or

your ISP), or click in Auto PVC. (Auto PVC causes the router to perform

automatic VPI/VCI detection as defined in DSL forum TR-068.) For VLAN,

specify a VLAN ID and priority.

6. Select NAT and Firewall if you want them active for this connection. Firewall

and NAT services must be enabled. See Firewall/NAT Services on page 3-21.

7. Select the quality of service (QOS). Leave the default value if your ISP did not

provide this information. Depending on the QoS you select, you may also

enter:

— PCR (Peak Cell Rate)

— SCR (Sustainable Cell Rate)

— MBS (Maximum Burst Size)

— CDVT (Cell Delay Variation Tolerance)

Following is a description of the different options:

Username - The username for the PPPoE access. This is provided by your

DSL service provider or your ISP.

Password - The password for the PPPoE access. This is provided by your DSL

service provider or your ISP.

3. Using the Web Interface

3-8 January 2005 6381-A2-GB23-10

Idle Timeout - Specifies that PPPoE connection should disconnect if the link

has no activity detected for the specified number of seconds. This field is used

in conjunction with the On Demand feature. To disable the timeout feature,

enter a zero in this field.

Authentication – Specifies the authentication protocol: Auto (the protocol is

selected by the Central Office modem), PAP (Password Authentication

Protocol), or CHAP (Challenge Handshake Authentication Protocol).

Keep Alive - When the On Demand option is not enabled, this value specifies

the length of time to keep the connection from being shut down for inactivity by

sending PPP LCP echoes to the PPP server. To ensure that the link is always

active, enter a zero in this field.

MTU - The Maximum Transmission Unit the DSL connection can send. It is a

negotiated value. The maximum specified value is 1500, although some

DSL/ISP providers require a larger value. The minimum MTU value is 128.

On Demand - Enables on-demand mode. The connection will disconnect if no

activity is detected after the specified idle timeout value.

Default Gateway – Specifies whether a default gateway is used.

Enforce MTU - Check this box if you experience problems accessing the

Internet over a PPPoE connection. This feature will force all TCP traffic to

conform with PPP MTU by changing TCP Maximum Segment Size to the PPP

MTU.

Debug - Enables PPPoE connection debugging facilities. See Remote Log on

page 3-36.

PPP Unnumbered – Specifies that the calling and answering routers will not

PPPoA Connection Setup

PPPoA is defined in the Internet standard RFC 2364. It is a method of

encapsulating PPP packets over ATM cells which are carried over the DSL line.

PPP (Point-to-Point Protocol) is a method of establishing a network session

between network hosts. It usually provides a mechanism of authenticating users.

LLC and VC are two different methods of encapsulating the PPP packet. Contact

your ISP to make sure which encapsulation is being supported.

By selecting PPPoA, you are forcing your router to act as the termination point for

the PPPoA connection. This frees up your PC resources and allows multiple users

to utilize the PPPoA connection.

To configure the router for PPPoA:

Procedure

1. Click on Setup and then click on New Connection. The default PPPoE

connection setup is displayed.

2. At the Type field select PPPoA and the PPPoA connection setup page is

and cannot begin with numbers.

4. Select or enter a VPI and VCI (as supplied by your DSL service provider or

your ISP), or click in Auto PVC. (Auto PVC causes the router to perform

automatic VPI/VCI detection as defined in DSL forum TR-068.) For VLAN,

specify a VLAN ID and priority.

5. Select NAT and Firewall if you want them active for this connection. Firewall

and NAT services must be enabled. See Firewall/NAT Services on page 3-21.

6. Select the encapsulation type (LLC or VC); if you are not sure just use the

default mode.

7. Select the quality of service (QOS). Leave the default value if your ISP did not

provide this information. Depending on the QoS you select, you may also

TSML

Troubleshooting Management Link (TSML) is a feature that lets authorized

Network Operations Center (NOC) personnel troubleshoot and manage the router

from the NOC.

The TSML connection (VPI 0, VCI 34) examines incoming packets, looking for

ICMP Echo Requests. If the TSML connection receives five ICMP Echo Request

packets with the same destination IP address within five seconds, it adopts the

destination IP address. The address can then be used to access the router. No

authentication is required over the link.

The TSML connection is automatically configured. The TSML Connection screen

shows the settings, but they cannot be altered and saved.

Enable/Disable DHCP

By default, the router has DHCP server (LAN side) disabled. If you already have a

DHCP server running on your network, do not enable the router’s DHCP server.

To enable or disable DHCP:

Procedure

1. From the Home screen, click on Setup.

2. Under LAN Setup, select LAN Configuration. This will bring up the screen

shown in Figure 3-15, LAN Configuration Screen.

3. Click on the Configure link in the LAN Group 1 window. The LAN Group 1

Configuration screen appears.

Figure 3-16. LAN Group 1 Configuration

4. The DHCP server is enabled when “Enable DHCP Server” is selected. If you

enable it:

— Specify a Start IP address. The Start IP Address is where the DHCP

server starts issuing IP addresses. This value must be greater than the

router's IP address value. For example, if the router's IP address is

192.168.1.1 (the default) than the Start IP address must be 192.168.1. 2

or higher.

— Specify an End IP address. The End IP Address is the last address the

DHCP server can issue. The ending address cannot exceed a subnet limit

of 254. The maximum IP address for a router using the default address is

3. Using the Web Interface

3-20 January 2005 6381-A2-GB23-10

192.168.1.254. If the DHCP server runs out of DHCP addresses, users

will not get access to network resources.

— Specify a Lease Time. The Lease Time is the amount of time a network

user will be allowed connection to the Router with their current dynamic IP

address. The amount of time is in units of seconds; the default value is

3600 seconds (1 hour).

Note: If you change the start or end values, make sure the values are still within

the same subnet as the router's IP address. For example, if the router's IP address

is 192.168.1.1 (the default), and you change the DHCP Start and End IP

addresses to be 192.128.1.2 and 192.128.1.100, you will not be able to

communicate with the router if your PC has DHCP enabled.

In addition to the DHCP server feature, the router supports the DHCP relay

function. When the router is configured as DHCP server, it assigns the IP

addresses to the LAN clients. When the router is configured as DHCP relay, it is

responsible for forwarding the requests and responses negotiating between the

DHCP clients and the server.

If the DHCP server and relay are turned off, you must configure the IP address,

subnet mask and DNS settings of every computer on your network. Do not assign

the same IP address to more than one computer. Your router must be on the same

subnet as the computers.

The Apply button will temporarily save these settings. To make the change

permanent, click on Tools (at the top of the page) and select System Commands.

At the System Commands page, click on Save All.

Changing the Router's IP address

Your router's default IP address and subnet mask are 192.168.1.1 and

255.255.255.0, respectively. This subnet mask allows the router to support 254

users. Since the DHCP server issues a maximum of 255 addresses, there is not

much advantage to changing the subnet mask to increase the number of

addresses. Further, remember that if you change your router’s IP address and you

have DHCP enabled, the DHCP configuration must reside within the same subnet.

The default gateway is the routing device used to forward all traffic that is not

addressed to a station within the local subnet. Your ISP will provide you with the

default gateway address.

The Hostname can be any alphanumeric word beginning with a letter and

containing no spaces. The domain name is used to in conjunction with the host

name to uniquely identify the router.

To change the router's IP address:

Procedure

1. From the Home screen, click on Setup.

2. Under LAN Setup, select LAN Configuration. This will bring up the screen

shown in Figure 3-15, LAN Configuration Screen.

There are three queues for each PVC: low, medium, and high priority. The Low

Priority Weight and Medium Priority Weight fields determine how the low and

medium priority queues share bandwidth after the high priority traffic is

accommodated.

Port Forwarding

Using the Port Forwarding page you can provide local services (such as web

hosting) for people on the Internet. When users send this type of request to your

network via the Internet, the router will forward those requests to the appropriate

PC. Port forwarding can be used with DHCP-assigned addresses, but remember

that a DHCP address is dynamic. If you were configuring a Netmeeting server, for

example, you would want to assign this server a static IP address so that the IP

address is not reassigned. Also remember that if an Internet user is trying to

3. Using the Web Interface

Bridge Filters

The bridge filtering mechanism provides a way for the users to define rules to

allow or deny frames through the bridge based on source MAC address,

destination MAC address and/or frame type. When bridge filtering is enabled,

each frame is examined against the defined filter rules sequentially, and when a

matched is determined, the appropriate filtering action (allow or deny) is

performed. The bridge filter will only examine frames from interfaces which are

part of the bridge itself. Twenty filter rules are supported with bridge filtering.

To enable Bridge Filters:

Static Routing

If the router is connected to more than one network, you may need to set up a

static route between the networks. A static route is a predefined pathway that

network information must travel to reach a specific host or network. You can use

static routing to allow different IP domain users to access the Internet through the

router.

To enable Static Routing:

Procedure

1. From the Home screen, click on Advanced.

2. Under Advanced, select Static Routing.

3. Using the Web Interface

6381-A2-GB23-10 January 2005 3-33

3. Specify the New Destination IP. This is the address of the remote LAN network

or host to which you want to assign a static route. Enter the IP address of the

host for which you wish to create a static route here. For a standard Class C IP

domain, the network address is the first three fields of the New Destination IP,

while the last field should be 0. The Subnet Mask identifies which portion of an

IP address is the network portion, and which portion is the host portion. For a

full Class C Subnet, the Subnet Mask is 255.255.255.0.

4. Specify the Gateway address. This is the IP address of the device that allows

contact between the router and the remote network or host.

5. Specify the Metric. This determines the maximum number of steps between

network nodes that data packets will travel. A node is any device on the

network (such as a router or switch).

Dynamic Routing

Dynamic Routing allows the router to automatically adjust to physical changes in

the network. The router, using the RIP protocol, determines the network packets'

route based on the fewest number of hops between the source and the

destination. The RIP protocol regularly broadcasts routing information to other

routers on the network.

To enable Dynamic Routing:

Procedure

1. From the Home screen, click on Advanced.

2. Under Advanced, select Dynamic Routing.

3. Using the Web Interface

3-34 January 2005 6381-A2-GB23-10

3. Specify the Protocol. The protocol is dependent upon the entire network. Most

networks support Rip v1. If RIP v1 is selected, routing data will be sent in RIP

v1 format. If Rip V2 is selected, routing data will be sent in RIP v2 format using

subnet broadcasting. If Rip V1 Compatible is selected, routing data will be

sent in RIP v2 format using multicasting.

4. Specify the Direction. This determines the direction that RIP routes will be

updated. Selecting In means that the router will only incorporate received RIP

information. Selecting Out means that the router will only send out RIP

information. Selecting both means that the router will incorporate received RIP

information and send out updated RIP information.

The Tools tab provides access to system commands and functions.

System Commands

To make changes permanent, click on Tools (at the top of the page) and select

System Commands. The following commands are used to configure the router:

Save all: Press this button in order to permanently save the current

configuration of the router. If you do restart the system without saving your

configuration, the router will revert back to the previously saved configuration.

Restart: Use this button to restart the system. If you have not saved your

configurations, the router will revert to the previously saved configuration upon

restarting. Connectivity to the unit will be lost. You can reconnect after the unit

reboots.

Restore Defaults: Use this button to restore factory default configuration.

Connectivity to the unit will be lost. You can reconnect after the unit reboots.

Remote Log

The remote log feature forwards all logged information to a remote PC. The type of

information forwarded to the remote PC depends upon the log level. Each log

message is assigned a severity level, which indicates how seriously the triggering

event affects router functions. When you configure logging, you must specify a

severity level for each facility. Messages that belong to the facility and are rated at

that level or higher are logged to the destination.

For PPPoE and PPPoA connections, select Debug if you want to log the

connection information. This is helpful when trying to debug connection problems.

Verify that the Debug box is checked on the PPPoA or PPPoE Connection Setup

screen.

Ta b le 3 - 2 defines the different severity levels.

Ping Test

Once you have your router configured, it is a good idea to make sure you can ping

the network. If you have your PC connected to the router via the default DHCP

configuration, you should be able to ping the network address 192.168.1.2. If your

ISP has provided their server address you can try to ping that address. If the pings

for both the WAN and the LAN side are successful, and you have the proper

protocols configured, you should be able to access the Internet.

To run a ping test:

Procedure

1. From the Home screen, under the Tools title, click on Ping Test.

2. Specify the target IP Address that you want to ping.

Optionally, specify:

— TOS Byte value. This is part of the IP header of the ping packet. Valid

values are 0 to 255.

— Packet size. Valid values are 36 to 65507.

— Number of echo requests. Valid values are 1 to 9.

3. Click on Test.

By default, when you select ping test, the router will ping itself three times. In

Figure 3-35, the router passed the Ping Test; this basically means that the TCP/IP

protocol is up and running. If this first test does not pass, the TCP/IP protocol is

not loaded. In this case, restart the router.

Modem Test

The Modem Test is used to check whether your router is properly connected to the

WAN Network by running OAM F4 and F5 end-to-end and segment tests. The test

may take a few seconds to complete. To perform the test, select your connection

from the list, select a Test Type, and click on the Test button.

Before running this test, make sure you have a valid DSL link; if the DSL link is not

connected, this test will always fail. Also, the DSLAM must support this feature.

Not all DSLAMs have OAM F4 and F5 support.

Troubleshooting

The Router Is Not Functional

1. Check to see that the power LED is green and the network cables are installed

correctly. Refer to the quick start guide for more details.

2. Check to see that the LAN and Status LEDs are green.

3. Make sure you are not connecting the USB and the Ethernet port to the same

PC at the same time.

4. Check the settings on your PC. Again, refer to the quick start guide for more

details

5. Check the router's settings.

6. From your PC, can you ping the router? Assuming that the router has DHCP

enabled and your PC is on the same subnet as the router, you should be able

to ping the router.

7. Can you ping the WAN? Your ISP should have provided the IP address of their

server. If you can ping the router and your protocols are configured correctly,

you should be able to ping the ISP's network. If you cannot ping the ISP's

network, make sure you are using the correct protocols with the correct

VPI/VCI values.

8. Make sure NAT is enabled if you are using private addresses on the LAN

ports.

You Cannot Connect to the Router

1. Check to see that the power LED is green and that the network cables are

installed correctly.

2. Make sure you are not connecting the USB and the Ethernet port to the same

PC at the same time.

3. Make sure that your PC and the router are on the same network segment. The

router's default IP address is 192.168.1.1. If you are running a Windows-based

PC, type ipconfig /all (or winipcfg /all on Windows 95, 98, or ME) at a

command prompt to determine the IP address of your network adapter. Make

sure that it is within the same 192.168.1.x subnet. Your PC's subnet mask

4. Troubleshooting

4-2 January 2005 6381-A2-GB23-10

must match the router's subnet mask. The router has a default subnet mask of

255.255.255.0.

4. Make sure NAT is enabled if you are using private addresses on the LAN

ports.

LEDs Blink in a Sequential Pattern

This typically means that either the kernel or flash file system is corrupted. Notify

your service representative.

The Status LED Continues to Blink

This means that the DSL line is trying to train but for some reason it cannot

establish a valid connection. The likely cause of this is that you are too far away

from the central office. Contact your DSL service provider for further assistance.

The Status LED is Always Off

1. Make sure you have DSL service. You should receive notification from your

ISP that DSL service is installed. You can usually tell if the service is installed

by listening to the phone line: you will hear some high-pitched noise. If you do

not hear high-pitched noise, contact your ISP.

2. Verify that the phone line is connected directly to the wall and to the line input

on the router. If the phone line is connected to the phone side of the router or

you have a splitter installed on the phone line, the DSL light will not come on.

Terminology

What is a Firewall?

A firewall is protection between the Internet and your local network. It acts as the

firewall in your car does, protecting the interior of the car from the engine. Your

car's firewall has very small opening that allow desired connections from the

engine into the cabin (gas pedal connection, etc), but if something happens to your

engine, you are protected.

The firewall in the router is very similar. Only the connections that you allow are

passed through the firewall. These connections normally originate from the local

network, such as users web browsing, checking e-mail, downloading files, and

playing games. However, you can allow incoming connections so that you can run

programs like a web server.

What is NAT?

NAT stands for Network Address Translation. Another name for it is Connection

Sharing. What does this mean? Your ISP provides you with a single network

address to access the Internet with. However, you may have several machines on

your local network that want to access the Internet at the same time. The router

provides NAT functionality that converts your local network addresses to the single

network address provided by your ISP. It keeps track of all these connections and

makes sure that the correct information gets to the correct local machine.

Occasionally, there are certain programs that don't work well through NAT. Some

games and other specialty applications have a bit of trouble. The router contains

special functionality to handle the vast majority of these troublesome programs

and games. NAT does cause problems when you want to run a server. See the

DMZ section below.

What is a DMZ?

DMZ really stands for Demilitarized Zone. It is a way of separating part of your

local network so that is more open to the Internet. Suppose that you want to run a

web server, or a game server. Normal servers like these are blocked from working

by the NAT functionality. The solution is to isolate the single local computer into a

DMZ. This makes the single computer look like it is directly on the Internet, and

others can access this machine.

A. Terminology

A-2 January 2005 6381-A2-GB23-10

Your machine isn't really directly connected to the Internet, and it really has an

internal local network address. When you provide the server's network address to

others, you actually provide the address of the router. The router fakes the

connection to your machine.

You should use the DMZ when you want to run a server that others will access

from the Internet. Internal programs and servers (like print servers) should not be

connected to the DMZ.

What is a Router?

The Internet is so large that a single network cannot handle all of the traffic and

still deliver a reasonable level of service. To overcome this limitation, the network is

broken down into smaller segments or subnets that can deliver good performance

for the stations attached to that segment. This segmentation solves the problem of

supporting a large number of stations, but introduces the problem of getting traffic

from one subnet to another.

To accomplish this, devices called routers are placed between segments. If a

machine wishes to contact another device on the same segment, it transmits to

that station directly using a simple discovery technique. If the target station does

not exist on the same segment as the source station, then the source actually has

no idea how to get to the target.

One of the configuration parameters transmitted to each network device is its

default gateway. This address is configured by the network administrators and it

informs each personal computer or other network device where to send data if the

target station does not reside on the same subnet as the source. If your machine

can reach all stations on the same subnet (usually a building or a sector within a

building), but cannot communicate outside of this area, it is usually because of an

incorrectly configured default gateway.
