Hogwash. There  is nothing inherently  more secure, easier to  secure or
simpler about NAT (or  PAT if you will) than using real  IPs with a real
firewall. Sure there are differences, but  that doesn't mean that NAT is
king in this area. I would much rather prefer a firewall with a deny all
policy using real IPs than worry  about NAT. Both methods block anything
not explicitly allowed, but using real IPs offers a lot more flexibility
in my opinion.
