Right.

The problem is "No response to STUN server".  This means it cannot 
contact it.  Why?  Possible answers:
- you are not connected to Internet (I suppose this is not your case, 
right?)
- there is a firewall which blocks those packets

STUN uses ports 3478 to 3479 (perhaps the following ones too), does a 
machine block these ports?
