The OpenBSD ipnat man pages are very clear and concise.  They don't have
much in the way of diagrams, though.

Why not check out OpenBSD btw?

Also look at ipfilter.org and click on the second link you see for a
diagram.

Isn't the main point that since the NAT addresses are not routable, that the
chances of intrusion are much much smaller?  The first router the packet
hits will drop anything in 192.168.x.x .

I guess I am lucky, since my clients just expect whatever I do for them to
work.  They don't want me to explain it to them :-) 

Cordially
