port forwarding problems

Hi!

Got a speedtouch 716g modem and for some reason I cannot seem to open ports.

This is what it looks like where I open ports: http://img132.imageshack.us/img132/1425/modemf.jpg

Even though I correctly fill out all the fields it wont seem to open.
Have tried disabling windows firewall aswell but that wont help either.

Help very very much appreciated.
Thanks

 

Ok I set up a static IP adress now but it still wont work.
And I have had the ports open before without a static ip, but when I moved my comp to another room it has stopped working.

Any other clues?

 

Im trying to be able to host games on Warcraft III so Im opening TCP+UPD ports 6112-6119
Nothing other than the location of the computer is changed.
I did change to the 2nd port on the routher though (physically, it has 1,2,3,4 ports and it was plugged to 1 first, then I changed to 2) but then changed it back again.
Nothing else changed manually but I did notice that the computer IP had been changed from .65 to .66 at the end.

Other than that theres nothing I can think of.. Thanks for trying to help
