You can add these addresses to the same IP pool that contains the address
pool used by the DMZ interface (in this scenario, the Pool ID is 200).
Click the Port Address Translation (PAT) using the IP address of the
interface radio button.
If you select the option Port Address Translation using the IP address of the
interface, all traffic initiated from the inside network exits the security
