[Nice] For some reason, my code doesn't actually communicate to my stun server...

[Youness Alaoui]

Yes, we got your previous messages, and I already answered about the issue.
The reason the unit tests don't work is that unit tests should work without
internet access, so they use the nice_agent_add_local_address to prevent any
connectivity checks with the external interfaces, so it forces libnice to use
the loopback device for testing. The sendto() fails because, I suppose, it can't
route the destination address on the loopback device.
