When attempting to play certain streaming video over wifi behind an astaro/sophos utm on a blackberry10 device we receive errors on device and log complains about broken pipe.
Below is from a facebook video link.

Also happens when trying to play trailers though cineplex or other movie apps. All works fine behind a standard home wifi router or on a 4g connection.

EDIT: Fixed by adding the http://media.westworldmedia.com and http://video.ak.fbcdn.net to the apple video workaround exception
