We are implementing TMG on a test-basis.  Some of our users stream RM data to watch business-related meetings/conferences.  In testing the setup, we keep having this kind of data fail.  The media player is set to not use any kind of web proxy.  Any clues as to what I'm doing wrong?

The streaming application filters are enabled, and there are no firewall policy rules blocking any traffic, but TMG is giving these entries:

A little more clarification.

I'm having to use the "RealAlternative" client for playing .ram files.  These files are essentially links that pull the .rm media from whatever server they are being hosted on. 

If I disable the TMG client on the pc, the .ram files are able to load and play as needed.  If I re-enable the TMG client after the initial loading, I am able to continue playing the stream. 

Hi,

please check if RTSP and PNM protocols are working when you use the SecureNAT client instead of the TMG client. If access with the SecureNAT client works, check the TMG client settings in the TMG MMC (Networking - Networks - Task pane - configure Forefront TMG client settings)

Hi,

Just out of curiosity as I have the same issue with windows media player.  What am I checking for when looking through TMG client settings?

Hi. What you change in sitting of tmg client  for resolve problem ?
