Having an odd behavior on a new install of wowza. I reboot the machine, try the content, it tells me connection can’t be established. I then disable the firewall, connect from a system and it plays. I then re-enable the firewall, try the content on a different system, and it plays now through the firewall. It’s almost like port 1935 won’t open until one system has made the connection. I am running windows 2008, 64 bit, using echo360. ---

That is very odd behavior. I have not heard of this before. I assume you have TCP port 1935 open on your firewall. Charlie ---

If you are using an RTSP/RTP, native RTP or MPEG-TS encoder then the UDP ports need to be opened incoming as well. Charlie ---

No, that is the beauty of Java. It will take advantage of a 64-bit platform when run on a 64-bit platform. Charlie ---

yes, port 1935 is open, I can see the systems connect with the firewall up once that first connection is made. It just seems to reject that intial connection. Wowza is up and running with a service account. The udp ports are outgoing only right, they don’t need to be open incoming too? ---

windows 2008 (and vista) don’t support a range of ports in the gui. Only 1 port at a time. Any ideas on how to open all the udp ports via command line? ---

Thanks for all the help. We noticed the firewall acting oddly on several windows 2008 servers. It took command line work to get the firewall to open all the time. ---
