udp based video streaming flow drop by 2811 router

Hi,all

Thamks in advance.

We have an mpls connectivity which is used for connecting all of our branches.

Currentally mpls provide us 18 mb ethernet connection which is terminated on 3750 switch.all working fine.video streaming (udp) sent by branches to each other working fine.We are plaanning to replace that 3750 switch to 2811 router at mumbai and delhi branch but problem is when we are replaced the switch with router video streaming applcation does not working properly.I mean stream sent by delhi branch does not get at mumbai branch or vice versa.So we are configured ip forward protocol udp 5501 command on munbai router.in effect now strean sent by delhi brach working properly.but stream sent by munbai does not get at delhi branch.strean sent by others branches to delhi working properly.Prtg graph shows that video strean traffic sent by mumbai router goes up to delhi outside ethernet interface which is connected to mpls network.but after that delhi router drop stream traffic.interesting part is we can copy files from mumbai to delhi branch.I mean other than udp video streaming we can sent any traffic.Is thier any issue with udp video traffic traffic from mumbai branch only because other branche can send video stream todelhi branch without any problem through same mplss ethernet connection.or is it possible that mumbai 2811 router modify the udp packets that can not process by delhi router?

I have this problem too.

The ACNS RTSP gateway is not an RTSP-based streaming server. Rather, it is a process running on the Content Engine that accepts an RTSP request and performs the initial RTSP handshake with RTSP-based clients (RealMedia, QuickTime, and so on) on behalf of the RTSP-based streaming servers available on the Content Engine. From information derived from the initial handshake operation, the RTSP gateway queries the URL filtering, rules, authentication, and unified name space (UNS) daemons to determine whether or not the content is pre-positioned.

After successful completion of uniformity checks, the RTSP gateway tunnels the request to the appropriate streaming media server on the Content Engine. It can tunnel the request to the RealServer, RealProxy, or Cisco Streaming Engine on the Content Engine, depending on the requested media type, the media server that is currently enabled, and the player agent that is requesting the content.

After the RTSP gateway tunnels the request to a particular media server and the media server and client negotiate the UDP ports, it continues with RTSP message passing (SETUP). When the RTSP client issues a PLAY request, the streaming server starts streaming the data to the client over UDP
