That's exactly what I've been trying to argue with Verizon.   But with
IPSEC, it no longer becomes natted, it goes down the IPSEC tunnel.  The
problem is that Verizon won't allow the IPSEC with private IPs, so you have
to use public.

All of our Softswitches are on public IPs, this interface was on a LAN IP to
connect to our IPSEC tunnel.
