Im a bit concerned, today i setup media player so i could watch videos on the 360, i got it working ok and i had allowed only the 360's ip to connect in on my pc firewall, i also have a router as well, anyway i ended up watching the video on the pc, once it had finished i was just looking at the firewall when i noticed data outgoing to the 360's ip, the thing i don't get is that it wasn't even on and i had closed media player, or so i thought but this data was outgoing anyway, what's up with that, im worried outside ip's could be faked to look like lan ip's or am i just being paranoid?
