Um can you give us just a little more info? We can't help you unless you know what steps you have taken, what sort of network equipment you have, etc. This one line fragment of a sentence doesn't tell me anything useful about your problem.

Although it is only one sentence, I think I'm having the same problem. In my house my slingbox runs great on my aspire laptop and my desktop but when I'm away on another network it won't run on the same laptop. It's plugged in to my Belkin 802.11 wireless g on a cable connection. Thanks

Well, if you've already opened the port and can't view, these are more questions:

1.) If the WAN IP on your router begins with the following numbers: 10, 192, 127, or 169 then your modem is also a router and we will need to do some things to get around what is called a "double NAT."

2.) Make sure you have enabled remote viewing on the Slingbox.
