Well, then the Windows 'FireWall' is not a firewall either, according to
that definition, since it does not monitor outgoing data either.
The author also states.....'I know someone will point out that my
description of NAT is a gross simplification and isn’t entirely accurate,
so I’m going to mention up front that I know that.'
I also agree with the author that firewalling is a byproduct of NAT. So
yes, NAT is not a true firewall, but you are 1000 times safer connecting
your always-on broadband connection to a 'NAT device' than directly to a
PC.

I agree.
