[f-nsp] Using outbound ACLs on JetCore modules

[Devon]

All:

We have recently switched from IronCore to JetCore modules. Back when we
were running IronCore, it was advised that we try to use only inbound
ACLs and not outbound ACLs as outbound ACLs placed more work on the box.
(I vaguely remember the person explaining to me that an outbound ACL
basically made an inbound ACL on all interfaces)

Is this still the case with JetCore? Or was I misled in the first place?
