Signing into your Linksys how?...

Open your Web Browser. IE or Netscape is fine. 

1) Type the IP for your Linksys Box.  By default that is 

2) A Username / Password Window will appear.  You only need a Password.   By default Linky's ship with admin all lower case. 
    type in your password and press enter.

How to get to your advance pages...

When you first log into your router this is the first page you will see. 

Figure B  This shows what your Current Linky's IP is.  If you were to ping this IP the Router itself would answer.  
                          This is also the IP you need when setting up a Static IP, because this become your Gateway IP.

Host Name:  This is a ID or Name that is provided by your ISP service.  This is also the Computer Name 
                                 that your ISP service has given you.  This can be used in conjunction with MACK cloning to help in using your router.

Domain Name: This is a ID or Name that is provided by your ISP service.  This can be used in conjunction with MACK cloning to help in using your router.

Firmware Version: This is the current Version of the Firmware you are using.

Wan Connection Type: This is tells the router to either get the IP info automatically or it can be set with permanent info provided by your ISP.

Setting a Static/Permanent IP address on your PC...

Before starting forwarding ports, I'd like to take a minute to go over what is needed to use static IP addresses on your LAN. With DHCP all the IP configuration information is passed on to all the clients. This includes IP address, default gateway IP address and the IP addresses of up to three DNS servers. Even if you disable DNS in TCP/IP properties, the DHCP server will still give you the DNS server to allow the computer to resolve names.

When using static IP addresses, you have to provide all this information yourself. And, you have to enable DNS. This is the only way you can enter DNS server information, and without it, you will not be having any fun.

So, if you are going to use static IP addresses, you'll need to enter at least one DNS server address and a default gateway address, plus a static IP address that is outside the range of what the router hands out. By default, the range used by the Linksys router is through Stay clear of those address (you have 203 other to choose from!).  Another idea is  to keep the Static IP LOWER than 100 or what you have set in the Starting IP Address field.

The documentation that comes with the router claims that you must disable the DHCP server if you are going to use port forwarding; also, the configuration page where you set up the port forwarding says the same thing. This is INCORRECT! You do not have to disable the DHCP server on the Linksys router to use any of the features on the router 1). What Linksys probably should have said is that it makes sense to use static IP addresses on the machines you are forwarding ports to (disable DHCP on the client).

Now that you have all you Network settings from your STATUS page you should go ahead and input all that info into windows network configuration.  Once that is done then reboot the computer.  

If you DNS, or Gateway IP change the computer that you set a static IP on will not have this new info. In this case your Static Computer will not work until you enter the new changed information.

Port Forwarding...

Port forwarding is a way of allowing outside users access to your LAN computers on a given port (or range of ports). Basically, if someone connects to the WAN IP address on port 80 on your router and you have set port 80 to be forwarded to an IP address on your LAN, then the router will allow that traffic to pass right through to the destination. To the outside world, it will seem like they are accessing the web server directly on the WAN IP address. The same goes for other services.

This is directly linked to the use of static IP address. The documentation that comes with the router claims that you must disable the DHCP server if you are going to use port forwarding; also, the config page where you set up the port forwarding says the same thing. This is INCORRECT! You do not have to disable the DHCP server on the Linksys router to use any of the features on the router 1). What Linksys probably should have said is that it makes sense to use static IP addresses on the machines you are forwarding ports to (disable DHCP on the client). When using DHCP, it is possible that you will not get the same IP address you had the last time. If you are forwarding ports to the old IP address, outside users will not be able to connect as the router will direct the traffic to the wrong computer. So, if you are going to set up a web server or a mail server, or any other type of server, then use a static IP address on that computer. 

With firmware 1.37, you can also specify TCP, UPD or Both to have better control over what type of traffic should be passed on to your LAN.

With Firmware 1.4+, you can also set up standard Port forwarding for HTTP, FTP, Telnet and others under the new "UPnP Forwarding" button found at the bottom of the "Forwarding" page.

How to Setup Port Forwarding.
Forwarding ports is actually quite simple. Using a web browser, connect to the LAN IP( default) of the router, and click the orange "Advanced" tab in the top-right corner. Then click the "Forwarding" tab to get to the port forwarding configuration screen. You can forward up to 10 ranges of ports. Simply enter the start port and the end port (same number in both if there's only one port), then enter the IP address of the computer you wish to forward to.  If your the only computer on the router then you can use, and then click the Apply button to save configuration. Once the router has re-started, traffic will be forwarded to the IP address selected.  Also Please remember Port Forwarding will not work if SPI is turned on.

DHCP what is it?...

DHCP (Dynamic Host Configuration Protocol)

Dynamic Host Configuration Protocol, or DHCP for short, is a convenient way for computers on a network to identify each other and make sure that data is transferred correctly. In order to better understand this, it is necessary to explain Internet Protocol (IP), and, more specifically, IP Addressing.

Using the Internet Protocol, computers and other networking devices on a network are assigned an identifying number, referred to as an IP Address. This address can be compared to the address of your house, and the mail that is delivered to you is like data. The postal worker knows to deliver mail (data) to your house by your address. The same is true for computers on a network. The network knows where to deliver data, according to the IP address it is being sent to. An IP address is in the form of XXX.XXX.XXX.XXX and must be unique for every computer on the network - if two houses in the same town had the same address, the mail (data) would always be mixed up!

IP addresses can be assigned in one of two ways. Using Static IP Addressing, each computer on a network is assigned a static, or permanent, IP address, just as your house has a permanent address. This address is usually assigned by a person, such as a network administrator. In the case of large networks (like the Internet), this can be very time consuming. The list of IP addresses in a large network and how they have been assigned can make record-keeping a full time job. However, it is still an effective and even easy way to assign IP addresses in a smaller network.

In larger networks, however, another way to assign IP addresses was needed. After all, in large companies, employees and computers are often moved on the network. Employees often have to log onto the network from remote locations, like hotel rooms when business traveling. If you physically moved your house to another part of town every week, imagine how difficult it would be for people to keep up with your address! (And how much the post office would resent you!)

This is where DHCP comes in. This protocol actually leases, or temporarily assigns, an available IP address to computers as they log on to the network. This IP address belongs to that computer during that session. When that computer is logged off the network, DHCP can assign that IP address to another computer when it logs on. The network keeps up with you efficiently, with no wasted IP address space. Other users (and network administrators) don't have to keep up with your address. And, in some ways, this provides some measure of safety from hackers, since you are not at the same IP address all the time.

DHCP is built into some operating systems, like Windows NT and Windows 2000. For users of operating systems like Windows 98 or Millennium, however, DHCP must be administered through another method.

I briefly touched on filters in the Basics page. Think of filters as the opposite of forwarding. It only works from the inside (as opposed to forwarding which works only on the outside), and instead of allowing traffic, it blocks it. This is one way to prevent certain types of traffic to leave your network. In the Basics page I set up a filter to block NetBIOS traffic from going out. If you have any application that are strictly LAN based, and you want to make 100% sure that it does not transmit any data onto the Internet, then you can filter out the port (or range of ports) on. As with Forwarding, this is in the Advanced section.

I am filtering ports 135 - 139 and also port 1975. There was a big controversy a short time ago about Aureate/Radiate and their software. Some "freeware" (or adware, really) applications comes with advertising built in. In stead of you paying for the program, you get to watch some ads as you use the software. The software also keeps track of which web sites you go to so it can better determine what types of ads it should display on your computer. The Aureate/Radiate spyware application uses (or used) port 1975 to talk to mother. Although I don't have any of the spyware, I'm still blocking that port.

UPDATE - Filters
Since it appears that port filtering may contribute to the instability of the Linksys router, I'm withdrawing my recommendation of filtering any ports. Although that makes it possible for certain traffic to get onto the internet, this should not have any significant effect on the security of your LAN.

UPDATE2 - Filters
As of Firmware Version 1.42 this instability of the Linky is gone.  Please feel free to add Port Filtering for 135-139 back in.

Dynamic/Static Routing...

For a home network, leave these at the defaults. This only applies if you have multiple routers on your network, and most home networks would not need this.

Back to Top


This is a fairly new feature.  Logging can be disabled or enabled. If enabled and with "255" left as the last byte of the IP address, the router will broadcast log information onto your LAN, hoping that some program will catch the information. If you want to capture this information, you're better of specifying the IP address where the logging application is running (see Setting a Static/Permanent IP address on your PC... above). You can also view the access logs on the router, but there's hardly any information there. It lists the IP address and port number of traffic passing through the router. This is fine to check and see if your SMTP traffic gets through, but it doesn't tell you anything about what else is hitting your router. You have no way of knowing if someone is trying to access a Sub-7 trojan on your computer, or is someone is doing a port-scan to see what ports are open. 

Since I'm running a web-server, the access log would be redundant, so I disabled it. The program "LogViewer" is available from LinkSys.  The better bet is to use the WallWatcher tool click HERE to check it out.

Linksys have chosen an interesting definition of DMZ(Demilitarized Zone). Essentially, it's a "public" computer. Setting the IP address in the DMZ field to match that of a computer on your LAN, you are essentially placing that computer outside the router. That means the computer is not protected by the router. Any incoming traffic which is not forwarded somewhere else will be forwarded to the computer in the DMZ. This is not a good place to be, but unfortunately, sometimes it is required. If you wish to use MS NetMeeting, you need to place your computer in the DMZ. Due to the fact that MS NetMeeting uses some random port allocation, the router wouldn't be able to pass the traffic to your computer otherwise.

How to set the DMZ
Open your Web browser and enter the  When prompted enter you password(Default is Admin).  Select the Orange "Advance"  Tab, then Click the "DMZ Host" Tab and enter the last 3 digits of your IP address(100 is correct if your the only computer on you router).  Then Press "Apply" Button to save the changes.

MTU Size...

MTU Size
This sets the maximum packet size that can be sent over the router. The maximum value is 1492. A smaller MTU forces more packets to be sent. More packets means more acknowledgement messages, and more packet header information. So, setting a smaller MTU value basically increases network overhead. However, if you have a network with high packet losses, it might be better to have a lower MTU size. (Resending a lost smaller packet is not so bad as having to resend a larger one.)

You'll want to make sure that your host has the same MTU size, or smaller. If you try to send a packet with a larger MTU size than the router supports, the router should respond with a ICMP 'Fragmentation required - DF set' message.1 This is bad, more network overhead, and your host is going to have to split up the packet anyway. A program that will let you tweak your PC network settings, such as MTU size is called DrTCP and can be found at

This router setting inforces the outgoing connection's MTU. Incoming (server) connections are not affected by this setting.

Stateful Packet Inspection(SPI)...

Stateful Packet Inspection (SPI)
Basically this is a Good Thing™. However, according to our friends at the BEFSR41 news site , you cannot use SPI with port forwarding. Port triggering, however, still seems to work with SPI enabled! Hopefully port forwarding will too in future firmware revisions. Basically, if you set up the router for any servers you can't use SPI.

SPI looks at each packet a little more in depth than just normal routing.3 It checks where the packet is going and where it is from and remembers this info for the future. If a packet comes to your door that has the right routing information, a normal NAT might just pass the packet on regardless. However, an SPI firewall might say, 'Hey, wait a minute, this packet is from somewhere that I haven't visited lately, its unsolicited, so I'm just going to ignore it.'

This has the effect of blocking unwanted bad stuff like trojan connection attempts and port scans. If a packet arrives that doesn't match one of your outgoing connections, it is simply ignored.

Port Triggering...

Port Triggering Overview
This is pretty slick (in my opinion). Basically, its standard port forwarding with a twist. When the router detects an outgoing connection on a specific port range, it will set up an incoming port forwarding rule (temporarily) on the ports you specify.

The BEFSR41 news site mentioned earlier has a good example of this involving SMTP. Another example is IRC. When you connect to an IRC server, often the IRC server connects back on 113 for an Ident lookup. However, often your router blocks these requests from getting back to your PC. If you were to set up a port trigger on ports 6000-7000 (a wide swath of ports, yes, but IRC servers usually are within this range) to forward the incoming port range 113-113, then the router will pass Ident requests.

Port Triggering - What is it?
Everything You Always Wanted to Know About Port Triggering But Were Afraid To Ask...

I have some applications for the newest BEFSR41 Port Triggering function so decided to test what it can and cannot do. I was a little disappointed it wasn't more elaborate but I guess I was expecting more.

All this info was compiled on a BEFSR41 f/w version 1.39.

What Is Port Triggering?
I think of Port Triggering as a way to dynamically forward ports to a LAN PC that needs them at a particular time. That particular time is when it runs a certain application that performs some event that "triggers" the router. This event must be an outbound access of a particular port range.

What is an example of Port Triggering use?
Connecting to an IRC server that needs an IDENT reply from you.

When you connect to an IRC server you use a port in the range 6660-6670. This connection is an ideal trigger because shortly after connecting the server will try and connect to your IDENT server to get a reply. Your end has to become an IDENT server and popular IRC client programs like mIRC have this server built in. But to make that PC an IDENT server it needs IDENT (port 113) forwarded to it.

I have 3 PCs getting LAN addresses automatically via DHCP so I cannot forward to them, right?"
The beauty of Port Triggering is it's dynamic like DHCP is. "Regular" Port Forwarding is static and should be to a static IP but Port Triggering is not static - it will work with DHCP LAN PC addresses!

Unfortunately, IRC's DCC (Direct-Client-to-Client) file transfer and chat functions needs other forwarded ports so just the IDENT example won't work by itself if you want to use DCC.

How would I set up Port Triggering for mIRC?
Go to the Advanced->Forwarding tab to find the "Port Triggering" button. Fill in this info on line 1:

Application Name: mIRC-IDENT
Trigger Port Range: 6660 - 6670
Incoming Port Range: 113 - 113

Press "Apply" then close the box with the "X". I found version 1.39 to be a bit strange when I hit "Cancel" or "Apply" more than once - I had to reset the router sometimes.

Can't the LinkSys know when mIRC is being run?
Absolutely not. Well, not like a personal firewall can. The LinkSys router is independant of the LAN PC's programs and operating system.

Then what's the "Application Name" do?
It's a reference so you know what the entry is for - what you put in does not affect the function.

So I can run any LAN PC on IRC and it will get IDENT forwarded to it?
Yes, you should be able to BUT... watch out for...

And run 2 PCs at the same time?
I knew you'd ask that! IRC is not a good example because if you try this on 2 PCs at the same time I find ONE AND ONLY ONE PC will get forwarded. This was part of my disappointment.

That's no good! I want to run 2 PCs at the same time on IRC!
What will happen on IRC is if PC#1 connects to an IRC server it will get IDENT fine. If PC#2 shortly comes along and connects to an IRC server PC#1 will still be forwarded IDENT. What's funny about this is PC#2 may connect just fine but it's PC#1's IDENT reply that did it! Fun, huh?

Be careful, this may not always happen because mIRC has an IDENT option "Enable only when connecting" so PC#1, even though it has IDENT forwarded to it may already be connected and not IDENT reply for PC#2.

IRC IDENT is a poor example for wanting to run 2 PCs at the same time using Port Triggering. Many games can make use of Port Triggering but the game would get all screwed up if the right PC didn't get the ports forwarded.

So what good is Port Triggering?
Well, you can't exactly run 2 PCs on Port Triggering at the same time but at least you don't have to change Port Forwarding for each PC when it wants to run IRC or a game that needs Port Triggering.

So when my sister gets done when can I get on with my PC?
You may have to wait up to 2 minutes is what I measured. My testing goes like this:

Once "triggered" the forwarding happens for 2 minutes unless a forwarded packet comes in OR another trigger event happens. Either resets this 2 minute timer. Once the 2 minute timer times out the next PC that triggers the magic event will "take over" the Port Triggering function.

What if my sister and I are on different IRC servers? Will it work then?
No, this is another disappointment my testing showed. I was hoping if different servers were used only the server triggered would be individually forwarded to the individual PC that caused it. But this is not the case.

Is the forwarding produced by Port Triggering only from the triggering server?
No, my testing showed it is a *global* forward. When Port Triggering is forwarding to a PC that PC is fully open on those "Incoming" ports from any host on the internet - the same as *regular* Port Forwarding.

On version 1.39 Port Forwarding doesn't work if SPI is enabled. Same with Port Triggering?
No! Port Triggering works even when SPI is turned on in version 1.39 (and 1.38.5 I suspect, too, but I only tested 1.39).

I want to run some games that connects to a game server but it doesn't work unless I forward certain ports. Will Port Triggering allow me to run that game from any PC?
Possibly. Check support boards for each game or check the "Web Links" ports list above to identify a "Trigger Port Range" which is usually the port(s) you connect to the server with. Then set the "Incoming Port Range" the same as the forwarded ports you needed before.

Keep in mind only one LAN PC can run the same game at any one time.

Can 2 different games be played?
I didn't test this but I do know one thing... if "Trigger Port Range" or "Incoming Port Range" overlaps between the 2 games it would be a fight to see which game works! 

Can I run a game server using Port Triggering?
I doubt it. Port Triggering is initiated from a LAN PC, NOT users out on the internet. Port Triggering has very limited value for servers - use Port Forwarding.

Hidden Features of Linksys...

Hidden Features in the 1.39.2+ Firmware

IMPORTANT! For reasons we can probably guess, these features have been intentionally hidden by the firmware coders. It stands to reason that they don't work, or that they're extremely buggy. I do not advocate trying these hidden features. If you opt to play with these features, you do so AT YOUR OWN RISK.

I'm going to assume you're router is at and has the default password of 'admin'. If it does not, you'll need to modify these links to get them to point to your router. Also, I've intentionally not made them real links because you really shouldn't be trying this at home.

Enhanced Logging Functions (aka Diagnostic Logging)
There are some hidden logging functions available in this firmware. This log information is sent to a client PC in the same way that the traffic logs are, via SNMPTrap. According to "mole2" this used to be known as "diagnostic logging" in previous firmware versions.11


The extending logging exists in the BEFSR41 as well. You can easily access this feature by clicking the "Log" tab, then click around the top of the "Log" tab near the blue bar. I couldn't find it at first because the mouse cursor didn't change into the "finger" pointer for some reason.

As far as I can tell, you can check off which SNMP messages you'd like your router to send out. However, most logging clients for the BEFW11S4 don't really know about these new logging functions.

SNMP Trap Watcher can receive all of the SNMP Messages that the router sends, apparently. I also recommend WallWatcher.  Check out  Utilities For the Linksys... for the WallWatcher.

Firmware upgrade tips...

The following tips may help you with the firmware upgrade process:

Try the new TFTP2 upgrade utility. Download from here.

It's a good idea to download a copy of the existing version of your firmware from the Linksys FTP site, so that you can restore it in case something goes wrong with the newer version of firmware that you are trying to load. If you can't find your exact version, just download the latest released version. 

Does the upgrade program successfully finish, but you can't bring up the Admin page?
Try backing off to the previous version of firmware and use the "Advance" button on the Upgrade Firmware program and set it to send Filename with path, and change the Initial delay to 1000ms.

The TFTP upgrade server is burned into the ROM of the router, and can't be erased. If something goes wrong with the upgrade and you get the dreaded steady "Diag" light on the router, just repeat the upgrade.

If you are having a NIC connection problem, you may have an upgrade fail and not be able to resurrect the router. DON'T PANIC!!!
Either connect the router to another computer with a different NIC, or connect a hub between your computer and the router (don't connect "Uplink" to "Uplink", connect "Uplink to a NORMAL port), and retry the upgrade.

You might have a problem upgrading or logging into the router if you use too strong a password. Some versions of the firmware are reported to have problems with mixed upper & lower case letters, or with characters other than numbers and letters. Some users have been able to use their password successfully on the router, but have it fail when trying to use the TFTP upgrade client.

We recommend trying to use as strong a password as possible, but if you have problems, try using a simpler password. You should also stay away from the characters "/" and "\" in your passwords, keep the length under 39 characters, and do not use any spaces in the password (your browser will translate the space character to '+'). 

Some firmware versions reset the password to "admin", so try that if your normal password doesn't work. 

If you still have problems upgrading due to getting your password rejected, try entering a blank password, then try the upgrade. Be sure to restore your password after you've successfully upgraded! 

STILL can't get the firmware to load? See this tip. 

Here's a copy of the installation instructions (Readme.doc) file that comes with the upgrade file:

How to upgrade the BEFSR41 Firmware 
The firmware on the EtherFast Cable/DSL Router (BEFSR41) has a 512KB flash 
chip that can be upgraded with a new firmware. Please read the instructions below to upgrade the firmware. 

1. Double click on Tftp to install the Upgrade Firmware software. Follow the screen and accept the default settings by clicking on Next a few times, then click on finish to finish the installation. 

2. Click on Start, Programs, Upgrade Firmware, then click on Upgrade Firmware. You should see the screen below. 

3. The following option is available.

Server- Enter the IP Address of the BEFSR41 that you assigned. By default, the router is as shown above.

Password- Enter the password you assigned the router. By default, the router’s password is “ADMIN”.

File- Click the triple “…” button to browse for the code.bin that was part of the extracted file you downloaded. In the example, the code.bin was extracted on the Windows desktop. 

4. Click Upgrade button to start upgrading. A progress bar should show up to show the progress.

Upgrade is complete.

UPnP what is it and how do I use it...

UPnP NAT Traversal FAQ
Do you have questions about Universal Plug and Play (UPnP) and Network Address Translation (NAT)? This article provides answers to some of the most commonly asked questions about a variety of UPnP, NAT, and UPnP NAT Traversal issues. 

Q. What is UPnP? 

A. Universal Plug and Play (UPnP) is an architecture for pervasive peer-to-peer network connectivity of PCs and intelligent devices or appliances, particularly within the home. UPnP builds on Internet standards and technologies, such as TCP/IP, HTTP, and XML, to enable these devices to automatically connect with one another and work together to make networking—particularly home networking—possible for more people. 

Q. What does UPnP mean to the consumer? 

A. Simplicity, choice and more innovative experiences. Networking products that include Universal Plug and Play technology will "just work" when physically connected to the network. UPnP can work with essentially any networking media technology, wired or wireless. This includes, for example: Category 5 Ethernet cable, Wi-Fi or 802.11B wireless networks, IEEE 1394 ("Firewire"), phoneline networking or powerline networking. As these devices and PCs are connected with one another, it becomes easier for users to take advantage of innovative new services and applications. 

Q. What is the UPnP Forum? 

A. The Universal Plug and Play Forum is an open industry consortium that was formed in June 1999 to help define the UPnP standards to simplify the networking of intelligent devices in homes and, longer term, within enterprises. The forum is achieving this goal by defining and publishing UPnP device control protocols and service control protocols. As of early June 2001, more than 350 companies are members of the UPnP Forum. The UPnP Forum is directed by the 22-member UPnP Steering Committee. A Technical Committee, Marketing Committee and a variety of working committees, each focused on a specific device category, also are set up to carry out the organization's efforts. A list of forum members, along with information on joining, is available at the forum Web site. 

Q. What are the technical elements of UPnP? 

A. UPnP is broad in scope in that it targets home networks, proximity networks, and networks in small businesses and commercial buildings. It enables data communication between any two devices under the command of any control device on the network. UPnP is independent of any particular operating system, programming language, or physical medium. UPnP supports zero-configuration networking and automatic discovery, whereby a device can dynamically join a network, obtain an IP address, announce its name, convey its capabilities upon request, and learn about the presence and capabilities of other devices. DHCP and DNS servers are optional and will be used if available on the network. Furthermore, a device can leave a network smoothly and automatically without leaving any unwanted state behind. UPnP learns from the Internet's success and heavily leverages its components, including IP, TCP, UDP, HTTP, and XML. UPnP involves a multi-vendor collaboration for establishing standard Device Control Protocols (DCPs). Similar to the Internet, these are contracts based on wire protocols that are declarative, expressed in XML, and communicated via HTTP. 

Q. What is NAT? Why is it used? 

A. Network Address Translation is an Internet Engineering Task Force (IETF) standard used to allow multiple PCs or devices on a private network (using private address ranges such as 10.0.x.x, 192.168.x.x, 172.x.x.x) to share a single, globally routable IPv4 address. A main reason NAT is often deployed is because IPv4—the current generation of the Internet - addresses are getting scarce. 

NAT is used in gateway devices that form the boundary between the public Internet and the private LAN. As IP packets from the private LAN traverse the gateway, NAT translates a private IP address and port number to a public IP address and port number, tracking those translations to keep individual sessions intact. Internet Connection Sharing in Microsoft® Windows® XP and Windows Me operating systems, along with many Internet gateway devices use NAT, particularly to connect to broadband networks such via DSL or cable modems. The use of NAT is increasing dramatically as more homes and small businesses network their PCs and share a connection to the Internet. 

Q. What is the problem with NAT? 

A. Put simply: NAT can "break" many of the compelling new PC and home networking experiences, such as multi-player games, real time communications, and other peer-to-peer services, that people increasingly want to use in their homes or small businesses. These applications will break if they use private address on the public Internet or simultaneous use of the same port number. Application must use a public address and for each session a unique port number. Large organizations have professional IT staff on hand to ensure their corporate applications can work with NAT, but smaller organizations and consumers do not have this luxury. UPnP NAT Traversal can automatically solve many of the problems the NAT imposes on applications, making this an ideal solution for small businesses and consumers. 

Q. Who came up with the NAT traversal solution? 

A. The NAT traversal solution is part of the work being done on the specification for the Internet Gateway Device (IGD) by the UPnP IGD Working Committee. UPnP member companies may join this committee or merely choose to monitor its progress. The chair of the committee is Prakash Iyer from Intel ( Many organizations, including Microsoft, drove this effort. 

Q. Are there other ways to solve the problem of NAT traversal? If so, why is using UPnP the best choice? 

A. Yes, there are other ways to solve this problem, but no other mechanism currently exists as an industry standard to address this problem in an automatic way for the consumer and in such a universally-applicable way for the developer. Other approaches require either manual intervention by the user or they require special development efforts by the Internet gateway device vendor and the software developer to handle the NAT traversal needs of specific applications. As a result, UPnP is uniquely able to solve this important problem. 

Consumer does the work. The manual intervention methods of NAT traversal require a consumer to use a browser, a graphical user interface-based tool on the PC, or a command line interface tool on the PC to change some settings on the Internet gateway device in the home. While some technical enthusiast users have little difficulty with this, many consumers do not feel comfortable doing this. Further, many consumers may not even realize that NAT traversal problems are interfering with their use of services across the Internet. The user may be attempting to play a multi-player game or engage in some other peer-to-peer service but find he or she cannot connect for some reason. This leads to troubleshooting, support calls, customer dissatisfaction, and reluctance on the part of the user to try new services or experiences in the future. 

Developer does the work. To avoid requiring the consumer to solve this NAT traversal problem manually, some Internet gateway device vendors have written and included application layer gateway support into their devices. This application layer gateway software is designed with specific applications in mind. In other words, the device vendor writes and tests specific code that will automatically enable one application to go through the NAT. If the application software is updated, the application layer code the device vendor wrote may have to be updated and tested again. This one-at-a-time way of chasing the NAT traversal problem is manageable for device vendors when there are only a few peer-to-peer or relevant applications to consider, but this approach does not scale well to 100s or 1000s of applications, can be very expensive to pursue, and likely requires specific knowledge of how each of these applications function. The better way to approach this problem is to have the device vendor add software or firmware to their device once to understand UPnP and have other devices and software be able to communicate with the NAT device using this same technology. UPnP is uniquely able to fulfill this role today. 

Q. What does the UPnP NAT traversal solution do? 

A. The scenarios that UPnP-enabled NAT traversal helps ensure include: 
Multi-player gaming 
Peer-to-peer connections 
Real time communications 
Remote Assistance (a feature in Windows XP) 
For IHVs this solution removes the need for writing and maintaining a database of Application Layer Gateways (ALGs) to traverse the NAT. This solution will be supported by both Windows XP and Direct Play, a programming resource in Windows, so software applications written to DPlay will be able to use the UPnP solution for NAT traversal automatically. 

The UPnP Forum's IGD spec achieves this automatic NAT traversal by providing methods for the following: 
Learning public IP address 
Enumerating existing port mappings 
Adding and removing port mappings 
Assigning lease times to mappings 

Q. Which vendors are implementing the UPnP NAT traversal solution? 

A. Currently most of the large gateway (DSL/Cable router) vendors have announced intentions to implement the UPnP NAT traversal solution in products they ship in 2001, beginning as soon as July. They include: Microsoft in WindowsXP, Linksys, D-Link, Intel, Netgear and Buffalo Technology, and Arescom. Some of these vendors have announced they will provide firmware or software upgrades to customers who already own their devices to add support for UPnP-enabled NAT traversal. 

Q. How does a consumer know which Internet gateway device has UPnP support? 

A. Consumers can check the Web site of their Internet gateway device vendor or read the label on the product packaging to see if this feature is included. Some retailers will know about this within the next few months. In the coming months, the UPnP Forum will make available a UPnP logo that vendors can include in their product packaging, marketing materials or on the products to indicate the product meets UPnP Forum's test requirements. 

Q. What resources are available to developers to implement this? 

A. There are a number of resources, from whitepapers to interoperability testing events (PlugFests). For technical papers, please go to For upcoming events, please see Microsoft provides developer information for Windows XP on MSDN Online.

Help- My router Diag light is blinking, how do I fix this?...

P R O B L E M 
My router Diag light is blinking after a Firmware Upgrade, how do I fix this? 

S O L U T I O N 
This is caused by a firmware not loading correctly. Follow the steps below to fix this.

Download the latest release firmware for your router from Be sure to select the correct model number of your unit.

Once downloaded, extract the files to a folder where you will be able to locate them.

The following files will be needed to perform the firmware upgrade:

Before performing the upgrade, it is recommended to do the following:

assign your computer a static IP address, for more information on this, see Setting a Static/Permanent IP address on your PC...

if using a 10/100 network adapter, change the speed to 10Mb ½ duplex.

At the windows desktop, go to:

Start > Settings > Control Panel

Double click on the network icon.

This will bring up the Network Configuration window.

Once in the Network Configuration, highlight the icon with the green logo for your network adapter, and click on the word Properties

This will bring up the Properties for the network adapter.

Go to the Advanced tab, select Connection Type 

* Note - The wording will vary depending on the make and model of your network adapter. Media Type, Connection Speed are two other wordings for the same function.

Change the value to the 10Base-t ½ duplex mode. This may also vary by make and model of the Network Adapter.

Once this is changed, click ok to go back to the Network configuration.

Click ok again and windows will ask to restart to make the changes.

Once this is done and the machine reboots, ½ duplex.

You are now ready to load the firmware on the router.

To test communication between the router and the network card do the following:

Go to Start > Run > type in: command and press enter.

This will bring up the MS-DOS prompt.


Type in: ping


The following result should appear.

Pinging with 32 bytes of data:

Reply from bytes=32 time<10ms TTL=128
Reply from bytes=32 time<10ms TTL=128
Reply from bytes=32 time<10ms TTL=128
Reply from bytes=32 time<10ms TTL=128

Now open the TFTP loader and there should be three fields in which to use:


the fields next to these should look as follows:

Password: ****** [this is admin by default, unless it has been changed]
File: C:\windows\desktop\code.bin [this would be how the file name would appear if you had saved the file to the desktop. For other folders, the path will look diffrerent]

Click on Upgrade.

A bar should appear in a box showing the status of the upgrade.

Once to the end the bar should disappear and a message that the firmware uploaded successfully should appear.

The light on the router should now have stopped blinking.

If this does not work, or you you are haiving difficulties in loading the firmware, contact Linksys technical support for further resolution.

Help-Reviving a "dead" Linky...

If you follow this procedure, you should be able to successfully load firmware into your router, even if you think you've tried everything. Follow the steps exactly and don't skip any! 

To reload the firmware when an upload fails or when the red error light is blinking, do the following:

1) Set a static IP Address on the Windows PC as following:

IP Address:

2) Make sure that you can execute the DOS command: "PING".

3) Make sure that the file name of the firmware code, given to TFTP.EXE, is "code.bin". RENAME the firmware file if you have to.

4) Try passwords in this order:

First: Try a blank password, 
Second: Try "admin" (don't enter the quotes)
Third: The password you assigned previously

5) After successfully uploading the firmware, press the Reset button to clear memory and select default settings.

6) Reconfigure the LinkSys as required to support your Broadband environment.


Another reader suggested a simpler method for reviving Linky:

1) Press and hold the Reset button for about 30 seconds

Remove power. Wait about 5 seconds. Reapply power.

HELP- My Firmware has become "Sticky"?...

Sticky Firmware is any firmware version that will not flash up or down a version level. 

To fix this please try the following method.  

  1. Save Routing settings; either print or write them down. 
  2. Make sure the Flashing Computer is the only computer connected to the LinkSys.
  3. Make sure that your Flashing Computer has a Permanent IP like not a IP given to it by the DHCP.  
    USE the following IPs when setting your Static IP.
    IP Address:
  4. Press and Hold the Reset key for 30 sec.  This will set everything back to default including your Password(admin)
  5. Flash the firmware using TFTP2.EXE instead of the TFTP.EXE supplied by LinkSys.  
  6. Turn off the Router and Modem.
  7. Turn Router and Modem back on; the New firmware should now be displayed in Setup Tab.  If not repeat again.
