Purpose
See the "Adding Network Objects for Real and Mapped
Addresses" section on page
If you want to perform identity NAT for all addresses, you can
skip creating an object for the the source real addresses and
instead use the keywords any any in the nat command.
If you want to configure destination static interface NAT with port
translation only, you can skip adding an object for the destination
mapped addresses, and instead specify the interface keyword in
the nat command.
See the "(Optional) Adding Service Objects for Real and Mapped
Ports" section on page 1-6.
