WebRTC dtls errors when sender and receiver are on different networks.

The ICE candidates I've receiving in a JSON message at the sender
(workstation, wired connection) from my Android app only have
reference to the local IP assigned by the network provider to the
phone.

For some reason even though the stun-server property of webrtcbin is
set to Google's STUN server, I am not receiving the public IP of the
phone.

Any ideas how I can debug this?
