I'm at my wit's end here. I'm trying to open a port for use with a Torrent client program, but my router, a D-Link DI-524, won't allow me to no matter what I try. I'll let these screenshots speak for me.

As you can see, I've turned off Windows Firewall, I've opened the port in exactly the way just about every Internet article directs me to, I've placed my machine in the "DMZ," which is SUPPOSED to mean unrestricted and unprotected access to and from this computer, and still, the port test comes up negative. Also, I'm 100% positive it's a problem with my router, because when I disconnect my router and connect the machine directly to the modem:

I have no idea what the problem is. Everything I've read tells me that this should be working, and it's not. Any help would be much appreciated.

Even DMZ is not a full translation. (DMZ is the last resort and most unsecure too) Use computer to connect to bypass the router if possible.

I am not a big fan of these share programs. How can you be sure it is trusted and installed correctly? Do you know anyone else that uses the program?

How can I bypass the router? Do you mean physically disconnecting it?

And, as far as security goes, this machine is toast as it is. It has a dead motherboard, among other things, which is why I only use it for unsecure things like this share program.

When he says bypass the router, I believe he means connecting it directly to your ISP's CPE (cable modem, DSL modem, etc) which you said you have already done and everything worked fine when you did that.

Is this a cable modem or DSL modem?

It's a cable modem. I disconnected my router just to see if it would work, but it can't be a permanent solution. I have four computers and one other device on this network that all need access to the Internet.

You're saying it's impossible to open the ports on the router? That can't be right.

Did you connect the computer to the modem directly and it worked? If so then we'd agree the router is at fault somehow.

Might get ethreal and see what is on the network. Guess there might a situation where one way it is dmz'd and not the other way. Check that your router is configured both receive and transmit.

Yes, it works when when I connect the computer directly to the modem, which is why I agree that it is the router's fault.

I installed Ethereal, but the entire program is Greek to me. What is it I'm looking for with this utility?

I don't know how to configure my router to both receive and transmit; I've never seen any settings to that effect, so I assume that it is set that way by default. Also, when I was searching for said settings, I stumbled on some firewall settings, so I played around with them. Not having any luck with specific settings, I allowed ALL IP addresses from ALL sources to ALL ports on ALL protocols, and still, no dice:

I'm really running out of "last resorts" here. I have no idea what security features are even left to completely disable.

Try using UPnP.

Fed up with Windows? Try Ubuntu Linux

I'm already using UPnP, I think. I don't think there's any more to it than this:

Did you set a static IP Address on your client? It's entirely possible that the torrent program itself is as fault: it may be rejecting the internal LAN network addresses used by the router to form the LAN. Your best chance is to contact the torrent client's maker and ask him.

That was a good idea to use UpnP. UpnP is a way for some applications to open the correct ports needed. (maybe a security hole too)

Guess you could tell us the name of the software and maybe we might have more ideas?

Ethreal is a way to monitor network traffic. It can capture traffic and display it. It can filter the packets based on almost any sort scheme. You capture traffic when you have computer to modem (without router)connected then start torrent. After a few minutes you can stop capture and look at the results. It should should packets based on time. It should should each receive and each transmit packet. In each packet there is a ton of info. That info includes ports. It should show ip and port on main page.

He's using Azureus. I would try using a differnet torrent client like uTorrent. It's much lighter and doesn't rely on Java.

I don't suppose this webpage:

would be of any assistance, would it?
