So, as long as there is the 'destination' (per the nonat acl) network somewhere on another interface, it doesn't matter which interface it's on for the nat exemption to work. Correct? Because once the traffic passes through the nat 'engine', then it just gets routed to the appropriate interface.
But you still have to apply the nat exemption to an interface, does that mean that it doesn't matter which interface you apply it to?
Maybe I'm overthinking this and missing something.
