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:

A.

Access the Router’s Web-based Utility by going to

or the IP address of the Router. Go

to the

Advanced Setup

=>

Forwarding

tab.

B.

Select the Service from the pull-down menu. If the Service you need is not listed in the menu, click the

Service Management

button to add the new Service Name, and enter the Protocol and Port Range. For

example, if you have a web server, you would enter the range 80 to 80. Click the

Add to List

button. Then

click the

Save Setting

button. Click the

Exit

button.

C.

Enter the IP Address of the server that you want the Internet users to access. For example, if the web

server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field provided. Check

“Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on getting an

IP address. Then check the

Enable

checkbox for the entry. Consider the examples below:

D.

Click the

Add to List

button, and configure as many entries as you like.

When you have completed the configuration, click the

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 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

or the IP address of the Router. Go

to the

Setup

=>

Forwarding

tab.

B.

Disable or remove the entries you have entered for forwarding. To delete an entry, select it and then click

the

Delete selected application

button. Keep this information in case you want to use it at a later time.

C.

Click the

DMZ Host

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 C: 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.

9.

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

Reset the Router to factory defaults by pressing the Reset button for ten 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

or the IP address of the Router. Enter

the default password admin, and click the

Setup

=>

Password

tab.

B.

Enter the old password in the

Old Password

field.

C.

Enter a different password in the

New Password

field, and enter the new password in the

Confirm New

Password

field to confirm the password.

D.

Click the

Save Settings

button.

directly to the LAN.

For Microsoft Internet Explorer 5.0 or higher:

A.

Click

Start

,

Settings

, and

Control Panel

. Double-click

Internet Options

.

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.

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

Hold the Reset button for up to 30 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.

12.I need to upgrade the firmware.

In order to upgrade the firmware with the latest features, you need to go to the Linksys website and download

the latest firmware at

13.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

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.

14.I need to use port triggering.

Port triggering looks at the outgoing port services used and will trigger the Router to open a specific port,

depending on which port an Internet application uses.

Follow these steps:

A.

To connect to the Router, go to the web browser, and enter

or the IP address of the

Router.

B.

Enter the password, if asked. (The default password is

admin

.)

C.

Click the

Advanced Setup

=>

Forwarding

tab.

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.

Once completed with the configuration, click the

Save Settings

button.

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

•

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

Is IPSec Passthrough supported by the Router?

Yes, enable or disable IPSec Passthrough on the VPN => VPN Pass Through tab.

Where is the Router installed on the network?

In a typical environment, the Router is installed between the cable/DSL modem and the 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.
