AFAIK it depends on your operating system. Windows XP versions make use of
UPnP and can use any port between 5004 & 65535 UDP.
If your firewall supports UPnP you need to enable it for video to work
(though there are some security concerns with doing this).
If your firewall doesn't support UPnP you will need to open all of the above
ports which is a definite security risk.
