Question

does flash player use inbound rtmp connections

so I'm using fiddler to monitor network traffic and I don't see any requests to port 80 while playing back FMS streams. And the same happens even when I block port 1935 inbound. So my question is this, does flash require port 1935 be open on the client machine's firewall inbound. Or can it playback and see live video with DVR functionality simply using outbound requests? If yes, then this is great news because it appears that windows 7 default firewall settings are to allow outbound requests on 1935.

But if not is there some tool I can use like fiddler to detect exactly what requests are being sent from the flash player and to which port.

    I did not get your question clearly. But as i i understood your question you wanted to know if port 1935 needs to open for inbound connections at client end too - am i right - if that was your question - answer is NO. 1935 needs to open for inbound connection at server end and at client end Flash Player can choose any at its disposal to make the socket connection.

    OK I want to know if the outbound firewall restrictions are off as they typically are for win7 and xp, but inbound firewall restrictions are on, can the flash player play media from FMS using port 1935. (which implies a question does FMS make any inbound connections to the client?). I do NOT want it to failover to port RTMP over port 80, of RTMPT over port 80. I want it as efficient as possible.

    Hi,

    Though I did not get your question correctly, I will try to answer a few things that I understand. In case you are talking about Firewall restrictions on the client, asl long as your firewall does not restricts incoming RTMP packets from FMS you should be able to play the media. When you connect to FMS on port 1935, a socket connection is established between FMS on 1935 and a port on client which is essentially a TCP connection. Also when you need to play the media your Flash player security sandbox settings should also allow you to access the internet. Also check this page to get more information on ports and firewalls http://kb2.adobe.com/cps/164/tn_16499.html.Hope this helps.

    Thanks,
