Netflow Analyzer Interface Data: Which Direction is "IN" and Which Is "Out"?

Netflow Analyzer Interface Data: Which Direction is "IN" and Which Is "Out"?

I've configured NetFlow on the outside interface of a Cisco ASA5510 firewall. Data flow is fine.

I know from the fw and other monitors we have that the majority of traffic on this interface is coming from the Internet in to our fw.

In NA, drilling down to the interface data and looking at the Traffic tab I find the traffic graph and the categories: IN and OUT. However, the majority of the traffic is displayed as "OUT".

So, I'm confused as to what direction you guys assign as "in" and "out" and can that be changed?

Thanks.
