You are correct in that one:many NAT isn't a "full" internet connection, and
I agree that it shouldn't be represented as such.

Not true. While I expect you will take this as nitpicking, one:one NAT is
very conveniently used for servers while one:many NAT can be used for
generic workstation access while preserving a consistent LAN numbering
scheme. Anything that a "full" internet connection gets you will also work
with one:one NAT.

This is laughable. You're telling me that we can't use our Alteons or
Arrowpoints that use NAT to provide (redundant and load balanced!) internet
services? I guess we should just go back to the One Big Web Server days, and
put all our MS SQL database servers out in "full" view of the internet. Now
there's any idea.
