Application to test STUN + broadband?


Hello I was wondering if someone knew of an application that could check
that the user has a firewall and a broadband connection that will work
OK with Asterisk and VoIP.
The app would first perform some bandwith + jitter tests, and will
then call a STUN server to check that the firewall isn't symetric. BTW, is Asterisk now STUN-capable, or is it still to map ports
manually on the firewall to connect it to a VOSP trunk? Thank you.
