Re: streaming through a firewall



Dave:

Some of those ports are udp (6970-9999). Make sure that you are opening udp, not tcp ports in this range.

It is a good idea to enable port 80 streaming as well. Clients may be behind restrictive firewalls that aren't under your control. Enabling port 80 streaming will get through most firewalls. With this enabled, streaming traffic is tunneled through tcp port 80.

Ideally you streaming server will have a "real" Internet IP address. Streaming from behind a NAT isn't recommended (tricky to set this up, and many NAT devices cannot be configured to handle it).

Hello,
 
I've had a Darwin streaming server setup now for a couple months and it is working great, internally.  A couple of weeks ago I needed to start testing to go live with the box and that's pretty much where I still am.  Here is my situation.
 
My web server is in a DMZ and hold .mov files created with MakeRefMovie.exe that point to the internal DSS.  I have opened up port 554 for RTSP traffic, opened up ports 6970-9999 and opened up port 7070 just to check everything.  When this did not work, I opened all the ports and tested it and it still does not work.  However, it works internally just fine still.  When I have someone else check it from the outside, or I check it from home, it does not work.  These movies are embedded in web pages.
 
I have tried a number of things, mostly related to the reference movies.  I've used rtsp:// and http:// and I've tried adding the port numbers to the lines.  I have referenced the DSS by name and by ip address.  None of these seem to make much difference, and most work internally, but not from outside of the local network.
 
I have verified that the web server in the DMZ can see the DSS server.  I've read about changing the settings of the server in the streaming server.xml file to the internal NAT address, but I didn't want to mess with that until I ask here.
 
Thanks for any help you can offer,
David
