It's not unusual for the port number to change for UPnP.

One thing that does stand out though is Bellsouth ... that rings an ominous bell to me. Perhaps I'm wrong. But do a forum search for bellsouth and see what you come up with. I am off the forums for a bit which is why I am not searching for you.

Ok I just did a very quick search ... found another user also with bellsouth & also using westell device, & they solved their problem by port forwarding. PortForward.com - Free Help Setting up Your Router or Firewall
