I made the exception in the firewall and checked the utilities I'm running, the only thing I haven't yet tried is disabling the extensions I have for Firefox to block adds & tracking cookies. I will try that today, and am going to burn a CD of my iPod tunes so I can load them to my Limebrary. Thank you for your help, I will work this out somehow! Hey, I disabled all my utilities, my browser extensions, and even disabled the firewall (Microsoft Windows) and nothing made the Advanced Tools firewall message go away, so I'm thinking it must be the router!? Any more suggestions?

Burn an mp3 or standard disk of them, not a standard Audio CD of them. Otherwise you will need to reconvert (down-convert) the music back to mp3/m4a, which is something that should never be done. That would mean a loss of music quality. mp3's should never be reconverted to mp3's.
If the problem is not your software firewall and not due to any security utility you are running. The problem could be your router/modem then. It may require port forwarding if you are willing.
What brand and model of connection devices are you using?

My IBM ThinkPad T42p has a Intel pro/wireless 2200BG net connect and the router is a Belkin 600-N Dualband WPA2-PSK.

You may have a double NAT effect.
The issue probably lays either at the wireless 2200BG settings end or the Belkin router. Most Belkins these days do have UPnP support but yours either may not be set to do so in its settings or has unreliable UPnP or simply does not possess the UPnP ability.

This does not look like the model version number, more like a descriptive name of that version.

Belkin usually hide the model number on the bottom of the router. It will be something like F1PI242E or F5D5230-4v2 or F7D2401v1 or F9K1105v1 or something similar to that. It will most likely be listed below the model name on the bottom of the router.

Do you know how to log into your Belkin router using your browser? One thing you can check is to see if UPnP is enabled. The initial Status window may list UPnP under the Features listing. This will at least show if it is enabled or not. Where the UPnP on and off switch is varies between models.

Log in address will vary between Belkin models. It might be either:
192.168.2.1
10.1.1.1
which you would copy into your browser's address bar. No need for any www or similar before the number. Just the number alone. Or at most, for example Password is often either admin or leave blank.

The Intel pro/wireless 2200BG settings
Is there a control panel that has these settings? If yes, check that UPnP is enabled.

UPnP is a system that allows a software program to communicate with a router to temporarily open one of the router's ports for incoming messages whilst the program remains open. Otherwise the ports remain blocked via the router's NAT settings.
If there is no easy answer to getting UPnP to work or UPnP does not exist in the router's firmware, then port forwarding would be the best step.

Ok, I enabled UPnP on the Intel wireless settings, and it was already there on the router. It did not help so I went ahead and did the port forward for GNUtella, sad to say there is still no joy! The song remains the same. Could it possibly have something to do with the shortcut I used to get around Java7??!

Highly unlikely.

Did you set up a static port before the port forwarding? Did you restart each device including computer?

Do you only have one software firewall or two? Windows firewall, any others?
Sometimes some security utility packages have their own firewall.

In LW, go Tools > Options > Advanced > Listening port & make sure that LW's Gnutella port & port in the 'manual port forward' box are the same number. If they're not, change both ports to the port number that you forwarded within your router & then click 'ok' at the bottom of the page.

And as LOTR said, you'd need to first have a static IP set up for your computer in order for port forwarding to work. In case you missed this step, the instructions are here: Setting a Static IP Address in Windows XP - PortForward.com

If neither of those suggestions help then maybe we need your system details in order to have a better look: System details - help us to help you -> Provide these details when you post!!!

Check underneath your router & see if there's a model number listed, apart from the one that you posted earlier.

Only one firewall. The port number is correct. I went to web page for static address and got stumped. It did not specify which address to use in Internet Protocol (TCP/IP) Properties. The router gave me LAN IP,SM,DG,DNS that matched what was in Windows IP Configuration. However the router also gave internet WAN IP,DG,DNS that were different, only the SM was the same. The router model # F9K1102V1

Go Start > Run > type in cmd > OK. Now type ipconfig/all & hit enter. You'll see an IP address in amongst the info. It will look similar to your default gateway, but the last digit(s) will be different.

For instance, my default gateway shows as 192.168.1.1 and my IP address shows as 192.168.1.10.
So 192.168.1.10 is the one that I've used within TCP/IP properties to set up my static IP.

In case you need to check your port forwarding, the guide for your router is here: http://portforward.com/english/route...1/Limewire.htm
Unfortunately, that guide's using screenshots from an older version of LW. You'll need to go to Tools > Options > Advanced > Listening port within your LW to set your port number etc.

Hope that all makes sense!

I hate to admit it but I'm in over my head! Apparently this old dog can't learn new tricks, my head is swimming with numbers and questions and I am just overwhelmed ! I'm sorry I let you down after all your help, thanks anyway!
