Trust me on this, I have tried almost everything to get it to work, the 
best you can hope for is one way audio in a dual NAT.

The answer has to do with where the packets are sent from and where they 
seem to be sent from.

If you are not familiar with OpenVPN, you should check it out.  It is a 
great piece of software and will solve your issues.
