Openfire MediaProxy Problem PortB

Im trying to establish a jingle connection over nats. My last resort is the mediaproxy. Right now I have my server in a amazon ec2 fedora instance with media proxy enable. When I ran my code using the ICETransportManager an RTPBridge is created. It assigns a port to PortA but to PortB it assigns port 0.

Is this a know bug? How do I solve this. If I ran the server locally in my mac it sets the ports right but in ubuntu and fedora using both the rpm and deb files to install openfire I have the same problem.

I need help, I have no idea how to solve this.

This is the error log:
