asterisk users - Sep 2005 - iax phone and asterisk server on different LANs

Hi,
I have a *IAX* phone connected to a LAN and I want to connect to it to 
make calls using an Asterisk server located inside another LAN behind a 
router (* hasn't a public IP)
I bought a IAX phone because SIP had problems with nat and so on.  ::))
How should I configure the IAX phone and Asterisk in order to make 
calls? Is it possible without touching the router configuration?

TIA

Giorgio

There should be no need to change the Asterisk configuration, IP-wise. 
Just configure the phone so that it knows the public IP address of the 
router on the remote LAN, and set up port forwarding on that router so 
that the IAX port is forwarded to the Asterisk box.

Not without sorcery! :)
