Actually, NAT on the address provides an additional layer of security. By 
allowing only particular IP address and port/application combinations to be 
natted, the user could effectively create a set of rules which would behave 
like a firewall. Example: If the only traffic which is natted is the inbound 
traffic on port 80 to your web server, then traffic on any other port 
inbound/outbound would effectively be dropped by a NAT device as it would not
know how to translate the traffic.
