• reg_key —Specifies a one-time registration key of your choice that you will also specify on the FMC
when you register the FTD. The registration key must not exceed 37 characters. Valid characters include
alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-).
• nat_id —Specifies a unique, one-time string of your choice that you will also specify on the FMC when
you register the FTD when one side does not specify a reachable IP address or hostname. It is required
if you set the FMC to
DONTRESOLVE . The NAT ID must not exceed 37 characters. Valid characters
include alphanumerical characters (A–Z, a–z, 0–9) and the hyphen (-). This ID cannot be used for any
other devices registering to the FMC.
Example:
> configure manager add MC.example.com 123456
Manager successfully configured.
If the FMC is behind a NAT device, enter a unique NAT ID along with the registration key, and specify
DONTRESOLVE instead of the hostname, for example:
Example:
> configure manager add DONTRESOLVE regk3y78 natid90
Manager successfully configured.
If the FTD is behind a NAT device, enter a unique NAT ID along with the FMC IP address or hostname, for
example:
Example:
> configure manager add 10.70.45.5 regk3y78 natid56
Manager successfully configured.
