 I am wondering how setup like this could work with IAX (or any other
 protocol) when symmetric NATs are used.

 If you have two different NATs then direct connection is not possible
 between hosts behind those two NATs. You have to do some kind of
 provisioning of the NAT boxes (i.e. port forwarding).
