Tried port 50000 everywhere... no connection.
Tried port 64049 everywhere... no connection.

Limewire still reports it detects a firewall.

Are we running out of options here? Is there any time of network monitoring we can do or logging you can turn on within Limewire?

I have been reading your problem with an amount of mild disbelief that you could be having so much problem but this "things" are sent to test us.

I'd like to ask a few questions which I hope you can answer.

1) You said that your wired desktop works with Limewire but your wireless desktop does not, apart from the modem connection what is the difference between the two desktops?

Unless you say something different, I shall presume that you are using both desktops to access the internet via your (single multi-user) modem.

2) You said that your modem has UPnP enabled, that's how LW on your desktop can work without port forwarding, therefore have you initialised UPnP on you wireless desktop? Simply because I don't believe it is currently turned on in XP by default, unlike the bad old days.

3) Have you enabled WEP or WPA encryption on your modem? Although it should not make a difference (and I would never recommend the following to a novice) I suggest you turn off encryption, enable UPnP on WinXP Pro, LW and your modem and then see what happens. But don't leave your modem in this state for too long because you effectively have no security.

4) You also say the you don't see the "brick wall in front of the globe", so it is likely that you do not have a "firewall" problem. Do you get an error message when LW cannot connect to the internet?

One other thing occurs to me, I recall that some Comcast members have in the past said that your ISP sometimes "bandwidth shape" (aka throttle) P2P connections, this might be something worth looking into.

Hope my suggestions can help throw some light on your predicament.

The hardwired box is running Windows XP Media Center. The wireless one XP Pro.
Both have McAfee Virus/Firewall and SpySweeper.

Yes


2) You said that your modem has UPnP enabled, that's how LW on your desktop can work without port forwarding, therefore have you initialised UPnP on you wireless desktop? Simply because I don't believe it is currently turned on in XP by default, unlike the bad old days.

UPnP is enabled. I can reach my router via the wireless PC and make port adjustments. But to make sure I had it enabled, I looked it up and I *think* you may be on to something.

My Windows Firewall is off. You go to the Exceptions tab, UPnP Framework is enabled. If you hit the edit button, TCP port is 2869 and the UDP port is 1900. Could this be the source of my problem, with ports not matching?


3) Have you enabled WEP or WPA encryption on your modem? Although it should not make a difference (and I would never recommend the following to a novice) I suggest you turn off encryption, enable UPnP on WinXP Pro, LW and your modem and then see what happens.

Yes, WPA security is on.


4) You also say the you don't see the "brick wall in front of the globe", so it is likely that you do not have a "firewall" problem. Do you get an error message when LW cannot connect to the internet?

That's incorrect. I indicated earlier that LW detects a firewall, even tho McAfee and the router firewalls are off.


One other thing occurs to me, I recall that some Comcast members have in the past said that your ISP sometimes "bandwidth shape" (aka throttle) P2P connections, this might be something worth looking into.

I don't even know how to investigate that angle. But I doubt that is the problem, since the hardwired has no bandwidth issues. And I have throttled back LW on uploads also.


Hope my suggestions can help throw some light on your predicament.

I think they might have with the UPnP enable question.

Thanks Bob. I will be visiting your country in September and touring around on the back of a Harley with two of my buddies.

I look forward to your ideas on the UPnP port issue.

Hi Ken

I hope that when you come to the UK you have a good time, but back to your problem.

There is a windows (XP) component that seems to go hand in hand with UPnP and that is the Internet Gateway Devices Discovery and Control, I would suggest that you check if this is installed as well.

I understand that this component helps windows to control your modem, your modem's user guide will tell you more.



UK Bob

Bob,

I checked on the IGD idea you have. It is already installed on this wireless desktop. But there is also a Peer-to-Peer option not installed.

But I have discovered a solution/work-around. I placed the wireless desktop's IP address in the DMZ on the router (i.e. outside of the protection of the router) and now Limewire works. The firewall indicator has disappeared.

This may be the only solution to this very frustrating problem. Any thoughts?

I appreciate all of your help of "Wondering Why" and from you Bob.

Ken

Apparently I spoke too soon... when I got home this evening, the wireless PC won't connect again. LW indicates a firewall is detected.

I suspect that since we obtain a dynamic IP address from Comcast ISP, the IP address I had last night is not the same now. Therefore the DMZ setting is useless now.

I guess I need to figure out another solution now, but at least I know its the Belkin router.

And Belkin's support was useless about this problem.

If anyone has anymore ideas, I would appreciate hearing them.

Ken

Are you using the McAfee Security Center, if you are try Port Forwarding the Firewall...
Port Forwarding for the McAfee Security Center

I have McAfee Firewall. I don't recall any port forwarding capabilities in the Firewall options. The only thing available is granting internet access.

And anyway, the same McAfee Firewall software is running (unchanged) on the hardwired PC and LW is running fine.

I think I have determined at this point that the Belkin Pre-N router is the issue. But I haven't figured out how to keep it from blocking LW on the wireless box. And as I stated earlier, Belkin support was no help. They told me to ask the LW vendor what to do. As you can see, passing the buck.

Ken

I was checking the thread "Still can't connect!!!!!!!!!! " for clues as what to do.

On the fourth post of that thread, it mentions changing protocols. This helped me solve my connection problem on my wireless desktop.

On my Belkin router, I had to set it to "block ICMP" pings which apparently changes protocols it accepts.

Now LW works! Check the protocols your router accepts and set the one that will allow LW to work for you.

Thanks to everyone who has helped along the way.

Ken

Hi Ken

Glad you got your wireless connection working, but I've got to tell you that it was not possible to see ICMP playing a part in your connection problems.

You see, I was aware of this ICMP control, i.e. allowing or not allowing it, but only as a function/facility within my Norton Personal Firewall (software), I was not aware that modem/router manufacturers had incorporated this facility within a hardware firewall (there is no such facility within my own modem/router).

Still, we all live and learn.

Saying all that, Belkin's helpdesk should certainly have been aware of this feature and advised you to turn if off.

You see, back in the old days when I was first on dial-up, and still with Virgin (my old P2P throttling ISP), I had problems connecting to the Internet. The first thing Virgin's help desk asked was did I have a Norton's firewall and was ICMP enabled.

So you see, these are basic things a technical help desk should know.

Anyway, thanks for the solution to your connection problem, I am sure that before long another unhappy LW user is going to ask for a solution to their Belkin/Wireless connection problem.
