Management IP address (MIP), which is an IP alias to one of the
master VPN Gateways in the cluster.
A connection to the VPN Gateway established through the
console port.
A list containing the serial numbers of revoked client certificates.
Each CA issues and maintains their own CRLs. If you generate
client certificates on the VPN Gateway, you can also create your
own CRL.
A request for a digital certificate, sent to a CA. On the VPN
Gateway, you can generate a CSR from the command line
interface by using the request command.
