My application has an existing TCP connection to the same server as
the STUN server.  Whatever interface the TCP connection is using, I
only want to use that interface to query for STUN responses and ignore
all others.   I'm pretty sure my VPN interface is also a gateway to
the internet, but it's likely the firewall on that network is very
restrictive and blocking UDP (haven't tested, just a guess).

I guess it is possible that the TCP connection is made on an interface
where STUN fails and another available interface works, but I feel
that this is not a common scenario.
