Eric,
I agree with most of your post but there is something that you have not
grasped IMHO.
It is true that "dissimulating" the private (RFC1918?) address does not
achieve much in terms of security: in order to access:

Daniel,

I think I don't agree with this. I would say that NAPT is a stateful
process but not that it uses inspection. By "inspection" I understand a
more intelligent process that decapsulates packets an

Security through obscurity. See Bellovin's paper on enumerating

when referring to NAPT, we are talking about rinetd, right? you can run
that on a linux box with two network interfaces (ethernet, ppp, token

Hackers first crack the exposed host. Then they see if it has multiple
interfaces. The local ARP cache will tell them the RFC1918 addresses if it
is a NAT.
The "NAT" just clusters several machines together in one machine.
Whether there are multiple machines behind a NAT is of little consequence.
