Overriding default IP addresses and ports

The FortiManager 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.

To override default IP addresses and ports:

1. Go to FortiGuard Server > Settings.
2. If you need to override the default IP address or port for synchronizing with available FortiGuard antivirus and IPS updates, click the arrow to expand FortiGuard Antivirus and IPS Settings, then toggle ON beside Use Override Server Address for FortiGate/FortiMail and/or Use Override Server Address for FortiClient, then enter the IP address and/or port number.
3. If you need to override the FortiManager system’s default IP address or port for synchronizing with available FortiGuard web and email filtering updates, click the arrow to expand FortiGuard Web Filter and Email Filter Settings, then toggle ON beside Use Override Server Address for FortiGate/FortiMail and/or Use Override Server Address for FortiClient and type the IP address and/or port number.
4. Click Apply.

   If the FDN connection status remains disconnected, the FortiManager system is unable to connect with the configured override.

FDN port numbers and protocols

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.
