The Micro-FortiGuard Server for FortiClient device’s built-in FDS connects to the FDN servers using default IP addresses and ports. You can override these defaults if you want to use a port or specific FDN server that is different from the default.
- Go to FortiGuard
- Expand FortiGuard Antivirus and IPS Settings or FortiGuard Web Filter Settings, as required.
- Toggle On beside Use Override Server Address.
- Enter the IP address and/or port number.
- Click Apply.
If the FDN connection status remains disconnected, the Micro-FortiGuard Server for FortiClient system is unable to connect with the configured override.
Both the built-in FDS and devices use certain protocols and ports to successfully request and receive updates from the FDN or override server. Any intermediary proxies or firewalls must allow these protocols and ports, or the connection will fail.
After connecting to the FDS, you can verify connection status on the FortiGuard Management page. For more information about connection status, see Connecting the built-in FDS to the FDN.
