NAT'ing happens first or routing?

[tharunraj22]

I want to know whether NAT transition happens first or the routing happens first in PIX?  As per my knowledge NATing happens first but when I tried the packet tracer tool in Cisco ASDM it shown like taking the Routing decision first.  Can any one confirm on this?

Hi,

Yup it does, can you paste your packet-tracer ?

Hi Tharun,

Traffic from OUTSIDE to INSIDE NAT happens first and traffic from INSIDE to OUTSIDE routing happens first.

Regards.
