6. I need to set up a server behind my Router and make it available to the public.
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.
1. Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Range Forwarding tab.
2. Enter any name you want to use for the Application Name.
3. Enter the Start and End Port range of the service you are using. For example, if you have a web server,
you would enter the range 80 to 80.
4. Select the protocol(s) you will be using, TCP and/or UDP.
5. 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 192.168.1.100, you would enter 100 in the field
provided. Check “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for
details on getting an IP address.
6. Check the Enabled option for the port services you want to use. Consider the example below:
Application Name

7. 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:
1. Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the Router. Go to
the Applications & Gaming => Port Range Forwarding tab.
2. Enter any name you want to use for the Application Name.
3. Enter the Start and End Port range of the service you are using. For example, if you want to host
Unreal Tournament (UT), you would enter the range 7777 to 27900.
4. Select the protocol(s) you will be using, TCP and/or UDP.
5. 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 192.168.1.100, you would enter 100 in the field
provided. Check “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for
details on getting an IP address.
6. Check the Enabled option for the port services you want to use. Consider the example below:
Application Name Start and End Port
Protocol
To IP Address
Enabled
UT
7777 to 27900
Both
192.168.1.100

UDP
192.168.1.100
When you have completed the configuration, click the Save Settings button.
8. 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.)
Appendix A: Troubleshooting
Common Problems and Solutions
59
Wireless-N Gigabit Router with Storage Link
Follow these steps to set DMZ hosting:
1. Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Range Forwarding tab.
2. Disable or remove the entries you have entered for forwarding. Keep this information in case you
want to use it at a later time.
3. Go to the Applications & Gaming => DMZ tab.
4. Select Enabled next to DMZ. For the computer you want exposed to the Internet, specify it by IP

16. The Power LED keeps flashing.
The Power LED flashes when the Router is first powered up. Meantime, the Router will boot up itself and
check for proper operation. After finishing the checking procedure, the LED stays solid to show that the
Router is working fine. If the LED keeps flashing after this time, the Router is not working properly. Try to flash
the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try using the
following settings, IP Address: 192.168.1.50 and Subnet Mask: 255.255.255.0.
17. 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.)
• If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it is
working correctly. You can remove the Router to verify a direct connection.
• Manually configure the TCP/IP settings with a DNS address provided by your ISP.
• 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

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.
Is IPSec Pass-Through supported by the Router?
Yes, it is a built-in feature that the Router automatically enables.
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 a LAN.
Does the Internet connection of the Router support 100Mbps Ethernet?
The Router’s current hardware design supports up to 100Mbps Ethernet on its Internet port; however, the Internet
connection speed will vary depending on the speed of your broadband connection. The Router also supports
100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Router.
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 98SE, Windows Millennium,
Windows 2000, or Windows 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.

Wireless-N Gigabit Router with Storage Link
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 ~ 27900. If you want to use the UT Server Admin, forward another port.
(Port 8080 usually works well but is used for remote admin. You may have to disable this.) 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 get 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 until the Power LED fully turns on and off. Reset your cable or
DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is available on
the Linksys website, www.linksys.com.
How will I be notified of new Router firmware upgrades?
All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be
downloaded for free. To upgrade the Router’s firmware, use the Administration - Firmware Upgrade tab of the
Router’s web-based utility. If the Router’s Internet connection is working well, there is no need to download a
newer firmware version, unless that version contains new features that you would like to use. Downloading a

Yes, but the Router’s setup pages are accessible only through Internet Explorer 4.0 or Netscape Navigator 4.0 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 E: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.
Does the Router pass PPTP packets or actively route PPTP sessions?
The Router allows PPTP packets to pass through.
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 it can only forward 10 ranges of ports.
What are the advanced features of the Router?
The Router’s advanced features include advanced wireless settings, filters, access restriction policies, port
forwarding, advanced routing, and DDNS.
How do I get mIRC to work with the Router?
Under the Port Forwarding tab, set port forwarding to 113 for the PC on which you are using mIRC.

What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to
communicate directly with each other. The ad-hoc network will not communicate with any wired network.
Appendix A: Troubleshooting
Frequently Asked Questions
66
Wireless-N Gigabit Router with Storage Link
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with
a wired network through a wireless access point.
What is roaming?
Roaming is the ability of a portable computer to communicate continuously while the user and computer are
moving freely throughout an area greater than that covered by a single access point. Before using the roaming
function, the workstation must make sure that it is the same channel number with the access point of dedicated
coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each
node and access point, for example, must always acknowledge receipt of each message. Each node must
maintain contact with the wireless network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a
system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates
such factors as signal strength and quality, as well as the message load currently being carried by each access
point and the distance of each access point to the wired backbone. Based on that information, the node next
selects the right access point and registers its address. Communications between end node and host computer
can then be transmitted up and down the backbone.
As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in
touch with the original access point or whether it should seek a new one. When a node no longer receives
acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM
(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available
worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in
the hands of users around the globe.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in
reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for
reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that
the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to
the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives,
Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
Appendix A: Troubleshooting
Frequently Asked Questions
67
Wireless-N Gigabit Router with Storage Link
What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that
is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical
channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence SpreadSpectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip
(or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if
one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can
recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low
power wideband noise and is rejected (ignored) by most narrowband receivers.
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
computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for
the network.
How do I reset the Router?
Press the Reset button on the back panel for about five seconds. This will reset the Router to its default settings.
How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing. Every obstacle placed between
the Router and a wireless PC will create signal loss. Lead glass, metal, concrete floors, water and walls will
inhibit the signal and reduce range. Start with the Router and your wireless PC in the same room and move it
away in small increments to determine the maximum range in your environment.
You may also try using different channels, as this may eliminate interference affecting only one channel.
I have excellent signal strength, but I cannot see my network.
Wireless security is probably enabled on the Router, but not on your wireless adapter (or vice versa). Verify that
the same wireless security method and passphrase/keys are being used on all devices of your wireless network.
How many channels/frequencies are available with the Router?
There are eleven available channels, ranging from 1 to 11, in North America. There may be additional channels
available in other regions, subject to the regulations of your region and/or country.
If your questions are not addressed here, refer to the Linksys website, www.linksys.com.

Appendix B: Wireless Security
Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of
Linksys products provide several network security features, but they require specific action on your part for
implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
Security Precautions
The following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):
1. Change the default SSID.
2. Disable SSID Broadcast.
3. Change the default password for the Administrator account.
4. Enable MAC Address Filtering.
5. Change the SSID periodically.
6. Use the highest encryption algorithm possible. Use PSK if it is available. Please note that this may reduce your
network performance.
7. Change the WEP encryption keys periodically.
For information on implementing these security features, refer to “Chapter 5: Configuring the Wireless-N Gigabit
Router with Storage Link.”
Security Threats Facing Wireless Networks
Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:
Change the administrator’s password regularly. With every wireless networking device you use, keep in mind
that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the only
person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too, can
change those settings. So, make it harder for a hacker to get that information. Change the administrator’s
password regularly.
Appendix B: Wireless Security
Security Precautions
69
Wireless-N Gigabit Router with Storage Link
SSID. There are several things to keep in mind about the SSID:
1. Disable Broadcast
2. Make it unique
3. Change it often
Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be
more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast
the SSID.
Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)
Hackers know these defaults and can check these against your network. Change your SSID to something unique
and not something related to your company or the networking products you use.
Change your SSID regularly so that any hackers who have gained access to your wireless network will have to
start from the beginning in trying to break in.
MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only
those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with
a random MAC Address.
WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security
concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job
more difficult.
There are several ways that WEP can be maximized:
IMPORTANT: Always remember that each device
in your wireless network MUST use the same
security method and key, or else your wireless
network will not function properly.
1. Use the highest level of encryption possible
2. Use “Shared Key” authentication
3. Change your WEP key regularly
PSK. PSK is stronger than WEP encryption, and PSK2 has stronger encryption than PSK. PSK and PSK2 gives you
a choice of two encryption methods: TKIP (Temporal Key Integrity Protocol), which incorporates Message Integrity
Code (MIC) to provide protection against hackers, and AES (Advanced Encryption System), which utilizes a
symmetric 128-Bit block data encryption. (AES is stronger than TKIP.)
PSK-Enterprise and PSK2-Enterprise use a RADIUS (Remote Authentication Dial-In User Service) server for
authentication. RADIUS uses a RADIUS server and WEP encryption.
Appendix B: Wireless Security

PSK/PSK2-Personal. Select the type of algorithm, TKIP or AES, and enter a password in the Pre-shared Key
field of 8-63 characters. Enter a Key Renewal period time between 0 and 99,999 seconds, which instructs the
Router or other device how often it should change the encryption keys.
PSK/PSK2-Enterprise. This method is PSK or PSK2 used in coordination with a RADIUS server. Enter the IP
address and port number of the RADIUS server. Then enter the key shared between the Router and its RADIUS
server. Then enter a Key Renewal period, which instructs the Router or other device how often it should
change the encryption keys.
RADIUS. This method is WEP used in coordination with a RADIUS server. Enter the IP address and port
number of the RADIUS server. Then enter the key shared between the Router and its RADIUS server. Enter the
WEP settings.
Implementing encryption may have a negative impact on your network’s performance, but if you are transmitting
sensitive data over your network, encryption should be used.
These security recommendations should help keep your mind at ease while you are enjoying the most flexible
and convenient technology Linksys has to offer.
