Hi,- First step, you need to

Hi,

- First step, you need to create objects or object-groups for your concerned hosts or subnet. You need to use these objects in NAT statements in version 8.3 or above.

- For NAT Exempt statements, you could use TWICE/MANUAL NAT by keeping same objects in Real and Mapped portion of NAT statement. 

- For Dynamic NAT statements, you could create Dynamic AUTO/Object NAT.

- For Static NAT Statements, you could create Static AUTO/Object NAT.

Please use the link below to understand and perform the same:

Creating Objects/ Object-group:

Twice NAT:

Please let me know if you have any query.

Thanks & Regards,
