I don't follow. AFAIK a non-NAT IP is an External IP.
When the gatekeeper in on a LAN then it can rewrite all signalling messages 
so that it appears that it's coming from an External IP.

Example:
GnuGK is installed in the routers DMZ on 192.168.0.1 however your external 
IP is 65.234.x.x  When a call comes from the Internet it will be appear to 
the caller that the GK is at 65.234.x.x. When a call comes from 
192.168.0.10 then it will appear as 192.168.0.1.

It routes both Signalling and Media so it can rewrite the source address to 
the external IP.
