Thanks Steve,
I don't know how I got so turned around thinking about it. I'll give
it a try tomorrow afternoon.

But how will that work for incoming calls? Assume that three phones
have registered with an Asterisk box from inside a NAT, then * knows
that these three users can be found at x.x.x.x port 4569.
Nope.
Asterisk would then know that these three users have registered from
NAT-ADDRESS:natted-port, where natted-port will be different for each
user.
When *
receives an incoming call intended for one of those users, all it can
do
is forward those calls to x.x.x.x:4569, right?
No, asterisk will send it to the same port the registration came from,
which should be different for each user.
In that case I don't
understand how the NAT can know to which user the incoming call is
referring.
Because when it sends out the registrations, each inside machine will
get a different external port assigned.

Hi folks,
Ok, I've seen this question go unanswered on the mailing list, and I
assume it's because no one had the heart to break the bad news to the
guy asking, but be honest with me, I can take it. At this time it's
flat impossible to have multiple IAX phones behind a NAT without using
an * gateway because there's no way to have
a client listen on a port besides 4569. Is my only option to learn
about SIP and attempt to forward that through my NAT?
Not true;
You just need the iax phones to register, and then they will work fine
through the NAT; whatever port they're on on local machines, and
whatever port they get NATted to won't matter.
