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.
