Windows Media Server in DMZ

Hey All,

I have a PIX 515E 7.2(2) with a Win2003 Server in the DMZ. I can stream traffic without problem's internally but externally it just doesn't work. I have all of the required ports open ( 1755, 554, 80, UDP -1024-5000,...) and there is nothing dropped in the logs but streaming doesn't work. If I move the Media Server out from behind the PIX it works great but behind the PIX it doesn't work. I can get to the web server on the media server but I'm not able to stream. What gives? I'm sure I've forgotten to add some detail's here but I'll be happy to add any info needed. Thanks!

hi .. I am assuming you have configured a one to one static NAT and that you have allowed incoming traffic on the ports you mentioned on the access-list applied to the outside interface correct ..?

Yes, you are correct. I have a one to one static NAT and have allowed incoming traffic on the outside interface for the ports I mentioned. I have also used the Packet Tracer in ASDM and it says the traffic will be accepted for all of the necessary ports from the outside to the DMZ.

check the fixup protocol in your configuration for RTSP protocol.

I don't believe 7.2(2) uses the fixup command anymore.

Thanks for the response and you are correct there is legacy support for the fixup command but I'm not actually using RTSP for streaming, I'm using ms-streaming(1755). I had opened RTSP but after watching some successful connections from my inside interface I could see that it wasn't needed when connecting from windows media player.

Okay, I am wrong about not using RTSP. I just checked a streaming connection and it is using RTSP so disregard my last comment. I'll try turning of inspection for RTSP.
