For whatever reason my initial impression was if it was possible for
external devices to connect without port forwarding...
I stand corrected.

It is not about an external network interface, but
external
traffic/devices. The NAT in this case is a port forwarding firewall, like
Amazon or Google cloud, where you have a local address on server and the
firewall is forwarding by port all traffic from an assigned public address.
Such scenario is quite common in enterprise environment, the devices on
local network connect by private IP, and the external devices connect to
the firewall ip and this one does port forwarding.

Slightly confused here... didn't he say that Kamailio and PBX are behind
NAT? If so, what external interface are we talking about?

Hello,
you do not need a second kamailio, the same instance can listen on
multiple sockets. You can also use a single ip, just listen on one port
for traffic from local network and on another port for external traffic
(this socket with advertise address).
If the router cannot handle dns query based on local traffic, most
devices support so called outbound proxy address, you can set that to
the sip server address with ip.
Cheers,
Daniel

That might work, provided that the router can
handle a local DNS.
It would, however still require adding an extra Kamailio instance with
another IP. Plus a branch of the invite to both local and public
instance. Plus an extra location table.
