Configure a FortiManager without Internet connectivity to access a local FortiManager as FDS

By default, FortiManager connects to the public FDN to download security feature updates, including databases and engines for security feature updates such as Antivirus and IPS. Your FortiManager can be configured to use a second, local FortiManager for FDS updates.

To use a second FortiManager as the FDS:

1. Go to FortiGuard > Settings.
2. Ensure that Communication with FortiGuard Server is set to Global Servers.
3. Under FortiGuard Antivirus and IPS Settings:
   1. Turn on Use Override Server Address for FortiGate/FortiMail and enter the IP address of the FortiManager unit being used as the FDS, and port number 8890.
   2. If required, turn on Use Override Server Address for FortiClient and enter the IP address of the FortiManager unit being used as the FDS, and port number 8891.
4. Under FortiGuard Web Filter and Email Filter Settings:
   1. Turn on Use Override Server Address for FortiGate/FortiMail and enter the IP address of the FortiManager unit being used as the FDS, and port number 8900.
   2. If required, turn on Use Override Server Address for FortiClient and enter the IP address of the FortiManager unit being used as the FDS, and port number 8901.
5. Click Apply.

   The FortiManager will use the second FortiManager unit as the FDS.
