Mike,

Yeah, I really don't know the solution to your problem but it appears
that your firewall surrounding your video servers might be the cause.

The way a normal TCP/IP session works is that the client connects to a
standard port and then that connection is handed off to a thread/process
that may or may not run on a separate port for that session. So your
firewall will need to handle that hand off the new connection. So make
sure the firewall is working with UDP and TCP data packets.

I also believe that you can either compile out or disable UDP
transmission on most video servers so you might take a look at that.
