How to verify FortiGuard connectivity
You can verify the FortiGuard connectivity in the License Information widget under System > Dashboard > Status. When FortiGate is connected to FortiGuard, a green check mark appears for available FortiGuard services.
From CLI, execute ping “service.fortiguard.net” and “update.fortiguard.net”.
Sample output:
FG100D# execute ping service.fortiguard.net
