<p>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.</p>
<p>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.</p>

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