Before adding an appliance to Forcepoint DLP Email Gateway, it is necessary to created a virtual appliance in the cloud service and performed initial configuration steps for the appliance. See the Forcepoint DLP installation guide for detailed installation and configuration information. Beginning with version 8.5, Forcepoint DLP Email Gateway may be deployed on a virtual appliance in Microsoft Azure. See Installing Forcepoint Email Security in Microsoft Azure for more information.

If you change either the appliance hostname or C interface IP address on the appliance, you must make the same change on the page Settings > General > Email Appliances. Forcepoint DLP Email Gateway does not detect this change automatically.
