Nat Interfaces; Guidelines For Nat - Cisco ASA Series Configuration Manual

Guidelines for NAT

The resultant ordering would be:

NAT Interfaces

In routed mode, you can configure a NAT rule to apply to any interface (in other words, all interfaces),
or you can identify specific real and mapped interfaces. You can also specify any interface for the real
address, and a specific interface for the mapped address, or vice versa.
For example, you might want to specify any interface for the real address and specify the outside
interface for the mapped address if you use the same private addresses on multiple interfaces, and you
want to translate them all to the same global pool when accessing the outside.

In transparent mode, you must choose specific source and destination interfaces.
