Select the + icon to add a private FortiGuard server.

Enable Antivirus and IPS Update Service for Private Server
When one or more private FortiGuard servers are configured, update AV and IPS through this private server instead of using the default FDN.
This option is available only when a private server has been configured.
Enable Web Filter and Email Filter Update Service for Private Server
When one or more private FortiGuard servers are configured, update the Web Filter and Email Filter through this private server instead of using the default FDN.
This option is available only when a private server has been configured.
Allow FortiGates to access public FortiGuard servers when private servers unavailable
When one or more private FortiGuard servers are configured, managed FortiGate units will go to those private servers for FortiGuard updates. Enable this feature to allow those FortiGate units to then try to access the public FDN servers if the private servers are unreachable.
This option is available only when a private server has been configured.
 
The FortiManager system’s network interface settings can restrict which network interfaces provide FDN services. For more information, see “Configuring network interfaces”.
