Hi TonicBH. If you get "The remote device indicated an abnormal state," that means there is a device listening and responding on the UPnP protocol port (5000), but it does not like the requests you are sending and is probably not a UPnP device. You can verify this by clicking "More Info", then "HTTP Messages", and finally "Last Response." It will probably say "HTTP/1.1 400 Bad Request." I get this behavior when I send UPnP messages to the other computer on my home network (or to my own computer!) instead of to the DSL modem.
The default IP address for the DSL modem on your home network (which might be just your computer and modem) is 192.168.1.1. Note that this is different than the external IP address the modem uses when communicating with servers on the Internet. Your computer is probably 192.168.1.2. The DSL Connection Tool that comes with MSN broadband is one way to verify these IP addresses. Select "Advanced Settings" and under "Internet Connection" you'll see your network card listed. Under that will be your IP address and a default gateway, which is the modem's IP address (assuming that your computer is connected to the modem using that network card).
When you think you know the local IP address of your modem, you can verify it by typing it into your web browser's address bar. Try clicking »
192.168.1.1 for example. If it is in fact your modem's address, you should get a nice page that says "MSN Broadband Modem Manager Tool." In the UPnP Interface program, you can set the modem's IP address by clicking the "More info" button and typing the correct IP address in the "UPnP device" box.
Reply again if the UPnP Interface program still doesn't work after you know you are using the correct IP address.
Good luck,
Jared Jacobs
