Connecting the built-in FDS to the FDN

FortiGuard Services : FortiGuard center : Connecting the built-in FDS to the FDN

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.

To enable the built-in FDS:

1. Go to System Settings > FortiGuard Center > Configuration.

2. 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”.

3. Select Apply.

The built-in FDS attempts to connect to the FDN. To see the connection status go to System Settings > FortiGuard Center > Configuration.


Disconnected	A red down arrow appears when the FDN connection fails.
Connected	A green up arrow appears when the initial FDN connection succeeds, but a synchronization connection has not yet occurred.
Out Of Sync	A gray X appears when the initial FDN connection succeeds, but the built-in FDS is disabled, and so cannot synchronize.
Synchronized	A green checkmark appears when the built-in FDS is enabled, and FDN package downloads were successfully completed.

If the built-in FDS cannot connect, you may also 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 routability, DNS, and any intermediary firewalls or NAT devices for policies that block necessary FDN ports and protocols.
