My Slingbox Solo located in the UK works fine when receiving the stream on the "Three" or "O2" mobile networks. In the USA roaming "Three" via AT&T works also.
However it will not stream to a PC connected via the UK Virgin Media network or the Comcast network in the USA. I've tried the standard port (5001) and currently port 8082 but still no joy on those particular networks. Has anyone found a way of getting round this problem?
