An administrator is attempting to add a new FTD device to their FMC behind a NAT device with a NAT ID of NAT001 and a password of Cisco0420l06525. The private IP address of the FMC server is…

When the Firepower Management Center (FMC) is behind a NAT device, the FTD must use the FMC's public IP address (209.165.200.225) to initiate the connection. The `configure manager add` command also requires a registration key and, in this scenario, a `nat_id` parameter ('NAT001') to inform the FMC that it is communicating via NAT, making the command `configure manager add 209.165.200.225 <reg_key> <nat_id>` correct.

The FTD cannot reach the FMC's private IP address (192.168.45.45) if the FMC is behind a NAT device and the FTD is connecting from outside the private network.

The `configure manager add` command syntax for the FMC IP address does not include a subnet mask in dotted-decimal format.

The `configure manager add` command syntax for the FMC IP address does not include CIDR notation (/27).
