designed as a security feature - it just does add to your security), NAT
isn't designed to secure your network - it just has that as a side effect.

If you want reliable security, get a device that's designed for providing
security (eg a firewall device, or an application level firewall installed
on your computers). On the other hand, if you just want "pretty good
security", then you can use NAT (but you /must/ practice "good computing" -
