Thank you Narbik,
So is this case it doesn't matter if the packet is coming inbound on
the outside interface, its simply matching on the destination IP
address? Can this rule be generalized to all NAT operations?
I guess what I'm trying to understand is does NAT care which direction
the packet is going (inside --> outside or vice versa) or is it simply
matching on the source or destination IP of the packet?
Regards,
Greg
