turnutils_stunclient is a basic STUN client
It sends a "new" STUN RFC 5389 request (over UDP) and shows the reply information.
The turnutils_stunclient program checks the results of the first request,
and if it finds that the STUN server supports RFC 5780
(the binding response reveals that) then the turnutils_stunclient makes a couple more
requests with different parameters, to demonstrate the NAT discovery capabilities.
This utility does not support the "old" "classic" STUN protocol (RFC 3489).
Usage:
$ turnutils_stunclient [options] <STUN-Server-IP-address>
Options with required values:
-p STUN server port (Default: 3478).
-L Local address to use (optional).
-f Force RFC 5780 processing.
