When you enable the built-in FDS and initiate an update either manually or by a schedule, the FortiManager system attempts to connect to the FDN.
If all connection attempts to the server list fail, the connection status will be Disconnected.
If the connection status remains Disconnected, you may need to configure the FortiManager system’s connection to the FDN by:
- overriding the default IP address and/or port
- configuring a connection through a web proxy.
After establishing a connection with the FDN, the built-in FDS can receive FortiGuard service update packages, such as antivirus engines and signatures or web filtering database updates, from the FDN.
- Go to FortiGuard > Settings.
- Enable the types of FDN services that you want to provide through your FortiManager system’s built-in FDS. For more information, see Configuring FortiGuard services.
- Click Apply.
The built-in FDS attempts to connect to the FDN.
If the built-in FDS is unable to connect, you may need to enable the selected services on a network interface. For more information, see Configuring network interfaces.
If you still cannot connect to the FDN, check routes, DNS, and any intermediary firewalls or NAT devices for policies that block necessary FDN ports and protocols.
