[libnice] Fwd: Re: STUN in NiceAgent

[Youness Alaoui]

Hi,

STUN exists as RFC3489 and RFC5389. The RFC3489 is used to find your
external IP address, and that's what "stun servers" should use. The
RFC5389 is more of a base protocol to be used as a tool for ICE. For stun
discovery, we need to use RFC3489, for ICE connectivity checks, we use
RFC5389. The stun server should detect we use RFC3489 and reply accordingly
anyway.
I would suggest you look at http://stunserver.org/ they use the 'stun'
project from here : http://sourceforge.net/projects/stun/

I hope that helps,
Youness.
