I have the same problem. I am trying to connect from my home vodafone broadband internet connection in New Zealand. I am able to connect no problem outside my home in New Zealand to my slingbox in the US. When I have my slingbox reset in the US it works at home in NZ until I disconnect then the same problem happens all over again. This only happens from my home vodafone broadband connection. The problem is obviously not with the connection in the US or with the slingbox. I don't know what else to do and I'm at my wit's end and ready to sell my slingbox.
