Yes. The main one is STUN, RFC 5389. Several related RFC and I-D are
made by the courageous BEHAVE working group
<http://www.ietf.org/html.charters/behave-charter.html>, which we can
all thank.

Whether Visa should have used STUN before extending RFC 3484 to IPv4
is another matter...

% ./client  stun.ekiga.net -v 
STUN client version 0.96
...
MappedAddress = 213.41.181.9:32143
                ^^^^^^^^^^^^
                My public address
