 Central License is the preferred and recommended method of licensing because it ties to the IP address of the management server and is not dependent on the IP of any gateway in the event it changes. Central License allows administrators to manage licenses for all Security Gateways from one central location. If the IP address of a gateway changes, the license remains valid as long as it is connected to the same management server. Central Licensing is supported with Gaia and is not the only option when deploying Gaia. Central Licensing does not tie to the IP address of a gateway and can not be changed to any gateway if needed.
