Cisco ASA with egress and ingress netflow

I have an ASA5510 running version 8.2.5 and has netflow configured. It only captures outbound traffic netflows, i.e. egress on the outside interface.

​

In newer versions of say 8.3 or 9.X does netflow support both egress and ingress?

I know that's the case for older versions of IOS of core routers, earlier versions only did ingress, then later versions supported both egress and ingress. Unlike the IOS on routers, the netflow on the ASA is not configured to a specific interface, its global.

​

Thanks
