An allowlist is an explicit listing of gateways that are allowed for enrollment.

The allowlisting option enables you to control the gateways that are allowed to enroll and the gateways that are not permitted to enroll. An allowed gateway is a virtual gateway created on the VMware Pulse IoT Center server. The virtual gateway is registered but not enrolled, and it does not have a physical gateway associated to it until a physical gateway is enrolled using the TPM-based authentication method.
