Chapter 1: Introduction
Welcome

Chapter 1: Introduction

Welcome

Thank you for choosing the Broadband Router with 2 Phone Ports. This Router will allow your computers to share
a high-speed Internet connection as well as resources, including files and printers. And after you have set up
your Internet phone service, you will be able to make phone or fax calls using the Internet.

How does the Router do all of this? By connecting your computers and peripherals, including phones or fax
machines, to the Router and connecting the Router to your cable or DSL modem, then the Router can direct and
control communications for your network.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share
Internet access, so you don’t need more than one high-speed Internet connection. With Internet phone service,
your Internet access can now be shared by your phones or fax machines as well. You will be able to make phone
calls using the account you set up with your Internet phone service provider, even while you’re surfing the
Internet. Plus, you can access one printer from different computers and access data located on another
computer’s hard drive. Networks are even used for playing multiplayer video games. So, networks not only are
useful in homes and offices, but also can be fun.

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.

ethernet: an IEEE standard network
protocol that specifies how data is
placed on and retrieved from a common
transmission medium.

lan (local area network): the computers
and networking products that make up
the network in your home or office.

browser: an application program that
provides a way to look at and interact
with all the information on the World
Wide Web.

mbps: one million bits per second; a unit
of measurement for data transmission.

nat (network address translation): NAT
technology translated IP addresses of a
local area network to a different IP
address for the Internet.

Chapter 2: Networking Basics
An Introduction to Local Area Networks

Chapter 2: Networking Basics

An Introduction to Local Area Networks

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

The Router connects your local area network (LAN), or the group of PCs in your home or office, to the Internet.
The Router processes and regulates the data that travels between these two networks.

The Router’s Network Address Translation (NAT) technology protects your network of PCs so users on the
Internet cannot “see” your PCs. This is how your LAN remains private. The Router protects your network by
inspecting the first packet coming in through the Internet port before delivery to the final destination on one of
the Ethernet ports. The Router inspects Internet port services like the web server, ftp server, or other Internet
applications, and, if allowed, it will forward the packet to the appropriate PC on the LAN side.

The Use of IP Addresses

IP stands for Internet Protocol. Every device in 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 Internet and
LAN connections.

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

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

static ip address: a fixed address
assigned to a computer or device that is
connected to a network.

nat (network address translation): NAT
technology translates IP addresses of a
local area network to a different IP
address for the Internet.

Chapter 2: Networking Basics

The Use of IP Addresses

If you use the Router to share your cable or DSL 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
Router. You can get the information from your ISP.

A dynamic IP address is automatically assigned to a device on the network. These IP addresses are called
dynamic because they are only temporarily assigned to the PC or other 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.

A DHCP server can either be a designated PC on the network or another network device, such as the Router. By
default, the Router’s Internet Connection Type is Obtain an IP automatically (DHCP).

The PC or network device obtaining an IP address is called the DHCP client. DHCP frees you from having to
assign IP addresses manually every time a new user is added to your network.

For DSL 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 connection 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. It also will provide the Router with a dynamic IP address to establish a connection to the Internet.

By default, a DHCP server (on the LAN side) is enabled on the Router. 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 Router,
see the Basic Setup section in “Chapter 5: Configuring the Router.”

dynamic ip address: a temporary IP
address assigned by a DHCP server.

dhcp (dynamic host configuration
protocol): a protocol that lets one device
on a local network, known as a DHCP
server, assign temporary IP addresses to
the other network devices, typically
computers.

Common Problems and Solutions

Appendix A: Troubleshooting

This appendix provides solutions to problems that may occur during the installation and operation of the Router.
Read the description below to solve your problems. If you can't find an answer here, check the your Internet
phone service provider’s website or the Linksys website at www.linksys.com.

Common Problems and Solutions

1. I don’t hear a dial tone, and the PHONE1 (or PHONE2) LED is not lit.

Go through this checklist until your problem is solved:

• Make sure the telephone is plugged into the appropriate port, Phone 1 or Phone 2.

• Disconnect and re-connect the RJ-11 telephone cable between the Router and telephone.

• Make sure your telephone is set to its tone setting (not pulse).

• Make sure your network has an active Internet connection. Try to access the Internet, and check to see

if the Router’s Internet LED is lit. If you do not have a connection, power off your network devices,
including the Router and cable/DSL modem. Wait 30 seconds, and power on the cable/DSL modem first.
Then power on the Router and other network devices.

• Verify your account information and confirm that the phone line is registered with your Internet phone

service provider.

2. I’m trying to access the Router’s Web-based Utility, but I do not see the login screen. Instead, I see a
screen saying, “404 Forbidden.”

If you are using Windows Explorer, perform the following steps until you see the Web-based Utility’s login

C. Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make sure

the security level is Medium or lower. Then click the OK button.

3. I need to set a static IP address on a PC.

The Router, by default, assigns an IP address range of 192.168.15.100 to 192.168.15.150 using the DHCP
server on the Router. To set a static IP address, you can only use the ranges 192.168.15.2 to 192.168.15.99
and 192.168.15.151 to 192.168.15.254. Each PC or network device that uses TCP/IP must have a unique
address to identify itself in a network. If the IP address is not unique to a network, Windows will generate an
IP conflict error message. You can assign a static IP address to a PC by performing the following steps:

For Windows 98 and Millennium:

A. Click Start, Setting, and Control Panel. Double-click Network.
B. In The following network components are installed box, select the TCP/IP-> associated with your

Appendix A: Troubleshooting
Common Problems and Solutions

C. Make sure you are using the right Internet settings. Contact your ISP to see if your Internet connection

type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers). Please refer to the Basic

Setup section of “Chapter 5: Configuring the Router” for details on Internet Connection Type settings.
D. Make sure you use the right cable. Check to see if the Internet LED is solidly lit.
E. Make sure the cable connecting from your cable or DSL modem is connected to the Router’s Internet

port. Verify that the Status page of the Router’s Web-based Utility shows a valid IP address from your

ISP.
F. Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on the Router,

cable/DSL modem, and computer. Check the Status tab of the Router’s Web-based Utility to see if you

get an IP address.

6. I am not able to access the Router’s Web-based Utility Setup page.

A. Refer to “Problem #4, I want to test my Internet connection” to verify that your computer is properly

connected to the Router.
B. Refer to “Appendix B: Finding the MAC Address and IP Address for Your Ethernet Adapter” to verify that

your computer has an IP Address, Subnet Mask, Gateway, and DNS.
C. Set a static IP address on your system; refer to “Problem #3: I need to set a static IP address on a PC.”
D. Refer to “Problem #12: I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up

window.”

7. I can’t get my Virtual Private Network (VPN) to work through the Router.

Access the Router’s web interface by going to http://192.168.15.1 or the IP address of the Router, and go to
the Security => VPN Passthrough tab. Make sure you have IPsec passthrough and/or PPTP passthrough
enabled.

VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will
work fine. At least one IPSec session will work through the Router; however, simultaneous IPSec sessions
may be possible, depending on the specifics of your VPNs.

Broadband Router with 2 Phone Ports

56

Appendix A: Troubleshooting

Common Problems and Solutions

VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Router.
AH has limitations due to occasional incompatibility with the NAT standard.

Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP address and
your local IP address. For example, if your VPN server assigns an IP address 192.168.15.X (X is a number
from 1 to 254) and your local LAN IP address is 192.168.15.X (X is the same number used in the VPN IP
address), the Router will have difficulties routing information to the right location. If you change the Router’s
IP address to 192.168.2.1, that should solve the problem. Change the Router’s IP address through the Basic
Setup tab of the Web-based Utility. If you assigned a static IP address to any computer or network device on
the network, you need to change its IP address accordingly to 192.168.2.Y (Y being any number from 1 to

254). Note that each IP address must be unique within the network.

Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec
server. Refer to “Problem #9, I need to set up online game hosting or use other Internet applications” for
details. Check the Linksys website at www.linksys.com for more information.

8. I need to set up a server behind my Router.

To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using.
For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and
port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the
documentation provided with the server you installed. Follow these steps to set up port forwarding through
the Router’s Web-based Utility. We will be setting up web, ftp, and mail servers.

A. Access the Router’s Web-based Utility by going to http://192.168.15.1 or the IP address of the Router.

Go to the Applications & Gaming => Port Range Forwarding tab.
B. Enter any name you want to use for the Application.

57

Appendix A: Troubleshooting
Common Problems and Solutions

C. Enter the port range of the service you are using. For example, if you have a web server, you would enter

the range 80 to 80.
D. Select the protocol you will be using, TCP or UDP, or select Both.
E. Enter the IP address of the PC or network device that you want the port server to go to. For example, if

the web server’s Ethernet adapter IP address is 192.168.15.100, you would enter 100 in the field

provided. Check “Appendix B: Finding the MAC Address and IP Address for Your Ethernet Adapter” for

details on getting an IP address.
F. Check the Enabled option for the port services you want to use. Consider the examples below:

When you have completed the configuration, click the Save Settings button.

9. I need to set up online game hosting or use other Internet applications.

If you want to play online games or use Internet applications, most will work without doing any port
forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet
application. This would require you to set up the Router to deliver incoming packets or data to a specific
computer. This also applies to the Internet applications you are using. The best way to get the information
on what port services to use is to go to the website of the online game or application you want to use. Follow
these steps to set up online game hosting or use a certain Internet application:

Application Start and End Protocol IP Address Enabled

Web server 80 to 80 Both 192.168.15.100 X

FTP server 21 to 21 TCP 192.168.15.101 X

SMTP (outgoing) 25 to 25 Both 192.168.15.102 X

POP3 (incoming) 110 to 110 Both 192.168.15.102 X

Broadband Router with 2 Phone Ports

Go to the Applications & Gaming => Port Range Forwarding tab.
B. Enter any name you want to use for the Application.
C. Enter the port range of the service you are using. For example, if you have a web server, you would enter

the range 80 to 80.
D. Select the protocol you will be using, TCP or UDP, or select Both.
E. Enter the IP address of the PC or network device that you want the port server to go to. For example, if

the web server’s Ethernet adapter IP address is 192.168.15.100, you would enter 100 in the field

provided. Check “Appendix B: Finding the MAC Address and IP Address for Your Ethernet Adapter” for

details on getting an IP address.
F. Check the Enabled option for the port services you want to use. Consider the examples below:

When you have completed the configuration, click the Save Settings button.

10. I can’t get the Internet game, server, or application to work.

If you are having difficulties getting any Internet game, server, or application to function properly, consider
exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an

Application Start and End Protocol IP Address Enabled

Appendix A: Troubleshooting
Common Problems and Solutions

application requires too many ports or when you are not sure which port services to use. Make sure you
disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority
over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding
settings. If the port number that the data enters from does not have port forwarding, then the Router will
send the data to whichever PC or network device you set for DMZ hosting.) Follow these steps to set DMZ
hosting:

A. Access the Router’s Web-based Utility by going to http://192.168.15.1 or the IP address of the Router.

Go to the Applications & Gaming => Port Range Forwarding tab.
B. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to

use it at a later time.
C. Click the DMZ tab.
D. Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet. This will

bypass the NAT security for that computer. Please refer to “Appendix B: Finding the MAC Address and IP

Address for Your Ethernet Adapter” for details on getting an IP address.

Once completed with the configuration, click the Save Settings button.

11. I forgot my password, or the password prompt always appears when saving settings to the Router.

Reset the Router to factory default by pressing the Reset button for 30 seconds and then releasing it. If you
are still getting prompted for a password when saving settings, then perform the following steps:

A. Access the Router’s web interface by going to http://192.168.15.1 or the IP address of the Router.

Enter the default password admin, and click the Administration => Management tab.
B. Enter a different password in the Router Password field, and enter the same password in the second

field to confirm the password.
C. Click the Save Settings button.

12. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.

If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway
for the Internet connection, the computer does not need any proxy settings to gain access. Please follow
these directions to verify that you do not have any proxy settings and that the browser you use is set to
connect directly to the LAN.

For Microsoft Internet Explorer 5.0 or higher:

A. Click Start, Settings, and Control Panel. Double-click Internet Options.
B. Click the Connections tab.
C. Click the LAN settings button and remove anything that is checked.
D. Click the OK button to go back to the previous screen.
E. Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users.

For Netscape 4.7 or higher:

A. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies.
B. Make sure you have Direct connection to the Internet selected on this screen.
C. Close all the windows to finish.

13. To start over, I need to set the Router to factory default.

Hold the Reset button for approximately five seconds and then release it. This will return the password,
forwarding, and other settings on the Router to the factory default settings. In other words, the Router will
revert to its original factory configuration.

Common Problems and Solutions

14. My DSL service’s PPPoE is always disconnecting.

PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a
period of inactivity, just like a normal phone dial-up connection to the Internet. There is a setup option to
“keep alive” the connection. This may not always work, so you may need to re-establish connection
periodically.

A. To connect to the Router, go to the web browser, and enter http://192.168.15.1 or the IP address of the

Router.
B. Enter the password, if asked. (The default password is admin.)
C. On the Basic Setup tab, select the option Keep Alive, and set the Redial Period option at 20 (seconds).
D. Click the Save Settings button.
E. Click the Status tab, and click the Connect button.
F. You may see the login status display as Connecting. Press the F5 key to refresh the screen, until you see

the login status display as Connected.

If the connection is lost again, follow steps E and F to re-establish connection.

15. I can't access my email, web, or VPN, or I am getting corrupted data from the Internet.

The Maximum Transmission Unit (MTU) setting may need to be adjusted. By default, the MTU is set at 1500.
For most DSL users, it is strongly recommended to use MTU 1492. If you are having some difficulties,
perform the following steps:

A. To connect to the Router, go to the web browser, and enter http://192.168.15.1 or the IP address of the

Router.
B. Enter the password, if asked. (The default password is admin.)
C. On the Basic Setup tab, look for the MTU option, and select Enable. In the Size field, enter 1492.
D. Click the Save Settings button to continue.

D. Enter any name you want to use for the Application Name.
E. Enter the Start and End Ports of the Triggered Port Range. Check with your Internet application provider

for more information on which outgoing port services it is using.
F. Enter the Start and End Ports of the Forwarded Port Range. Check with your Internet application provider

for more information on which incoming port services are required by the Internet application.

17. When I enter a URL or IP address, I get a time-out error or am prompted to retry.

Go through this checklist until your problem is solved:

• Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address,

Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.

• If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and

powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power

connections.)

Frequently Asked Questions

What is the maximum number of IP addresses that the Router will support?

The Router will support up to 253 IP addresses.

Where is the Router installed on the network?

In a typical environment, the Router is installed between the cable/DSL modem and the local area network (LAN).
Plug the Router into the cable/DSL modem’s Ethernet port.

Does the Router support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the global standard for
communications. IPX, a NetWare communications protocol used only to route messages from one node to
another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used for LAN
to LAN connections, but those protocols cannot connect from the Internet to the LAN.

What is Network Address Translation and what is it used for?

Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that
is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is
never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet
accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may
have many private addresses behind this single address provided by the ISP.

Does the Router support any operating system other than Windows 98, Millennium, 2000, or XP?

Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.

Does the Router support ICQ send file?

Yes, with the following fix: click ICQ menu => preference => connections tab=>, and check I am behind a
firewall or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then

send a file to a user behind the Router.

Frequently Asked Questions

I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do?

If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN
computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can
also use a port forwarding range of 7777 to 27900. If you want to use the UT Server Admin, forward another port
(8080 usually works well but is used for remote admin. You may have to disable this.), and then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and
ServerName to the IP assigned to the Router from your ISP.

Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP
address?

It depends on which network game or what kind of game server you are using. For example, Unreal Tournament
supports multi-login with one public IP.

How do I get Half-Life: Team Fortress to work with the Router?

The default client port for Half-Life is 27005. The computers on your LAN need to have “+clientport 2700x”
added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect
to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at
the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server
does not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.

How can I block corrupted FTP downloads?

If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP
program.

The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the
screen. What do I need to do?

Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your
Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s

Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at
www.linksys.com for more information.

If all else fails in the installation, what can I do?

Reset the Router by holding down the Reset button for approximately five seconds. Reset your cable or DSL
modem by powering the unit off and then on. Contact your Internet phone service provider for assistance. Refer
to “Appendix H: Contact Information” for contact information.

Will the Router function in a Macintosh environment?

Yes, but the Router’s setup pages are accessible only through Internet Explorer 5.0 or Netscape Navigator 5.0 or
higher for Macintosh.

I am not able to get the web configuration screen for the Router. What can I do?

You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet
Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make
sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is
set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape
Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct
connection to the Internet.

What is DMZ Hosting?

Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications
require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you
want to use DMZ Hosting. To get the LAN IP address, see “Appendix B: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”

Broadband Router with 2 Phone Ports

67

Appendix A: Troubleshooting
Frequently Asked Questions

If DMZ Hosting is used, does the exposed user share the public IP with the Router?

No.

Is the Router cross-platform compatible?

Any platform that supports Ethernet and TCP/IP is compatible with the Router.

How many ports can be simultaneously forwarded?

Theoretically, the Router can establish 520 sessions at the same time, but you can only forward 10 ranges of
ports.

Does the Router replace a modem? Is there a cable or DSL modem in the Router?

No, this version of the Router must work in conjunction with a cable or DSL modem.

Which modems are compatible with the Router?

The Router is compatible with virtually any cable or DSL modem that supports Ethernet.

How can I check whether I have static or DHCP IP addresses?

Ask your ISP to find out.

How do I get mIRC to work with the Router?

Under the Applications & Gaming => Port Range Forwarding tab, se t port forwarding to 113 for the PC on which
you are using mIRC.

What is a MAC Address?

The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet
networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all
practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a
