NAT breaks lots of things from the Internet Protocol layer up. In general,
it's not reasonable to expect a protocol to run over NAT unless someone
has analyzed the protocol and the implementations of the protocol and
determined that they don't violate any of a fairly large number of
(quite reasonable) assumptions.
(see http://www.cs.utk.edu/~moore/what-nats-break.html for a list)
This is an inherent characteristic of any NAT implementation. The only
'bug' is that the problems with NATs are not adequately documented - so
people blame the app or the protocol for problems caused by the imposition
