There's also a general perception that NAT increases security; some "security" companies go so far as to say NAT removes the need for a firewall. It's amazing how many network admins believe this.
Some also say that firewalls/nats remove the need to secure your systems.
They would also be wrong. Picture one user, with a wireless port or direct-dial modem, also attached to your internal LAN. NAT or no NAT, FW or no FW, your data is toast unless you trust them explicitly. This includes 100% of your internal users. FALLACY: NAT, Firewalls, and bastion-hosts, make your LAN secure.
