smoking crack - I can't tell but is there a glass pipe anywhere about?

NAT and port forwarding are indeed 2 different things. 

NAT is all about routing all ports whether inbound or outbound. You
could have NAT that routes traffic to public or private IP's but there
would have to be a device / appliance to handle the routing.

Port forwarding would generally refer to one IP address on a
firewall/gateway/router device where attempts to reach a specific port
are sent through to a computer / appliance that is behind the firewall /
gateway / router that has a private IP address.
