I'm trying to allow streaming from our server that is behind a 2811 router. I am using nat and have configured a one to one mapping of the external address to the internal ip address.I have the access list to allow tcp port 554 and initally had an inspect rtsp statement for the firewall.
I tried to follow this article "NAT RTSP Support Using NBAR"
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gtnrtsp.html#wp1047732 but I get an error saying "NAT: System defined port 554 is not configurable"
Anyone know how to get this working?
