Q. Does NAT occur before or after routing?
A. The order in which the transactions are processed using NAT is based
on whether a packet is going from the inside network to the outside
network or from the outside network to the inside network. Inside to
outside translation occurs after routing, and outside to inside
translation occurs before routing. Refer to NAT Order of Operation for
more information.
