But how will that work for incoming calls?  Assume that three phones

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.
