Description

This article describes how to verify and troubleshoot FortiGuard connectivity on FortiManager.

Anti-virus updates will be used as example.

Scope

FortiManager.

Solution

The terminology used in this document:

FDS= FortiGate AV/IPS.
FGD= FortiGate Web-/Email filter.
AV= Anti-Virus.
IPS= Intrusion Prevention System.
WF= Web-Filtering.
AS= Anti-Spam

Ensure that FortiManager able to populate the product support coverages of the manage firewall.
Go to FortiGuard -> License Status.

Ensure that FortiGuard communication is enabled.

AntiVirus and IPS Service needs to be 'ON' and FortiGate/FortiMail/FotiSandbox/FortiClient/FortiSwitch version has to be checked.
FortiProxy is having the same service as FortiGate.

Verify that service access for FortiGate Updates (FDS) or Web Filtering (FGD) are enable on FortiManager management interface.

The managed unit will not able to get the update if it is not enabled.

Check the FDS server list.

From the CLI, use the following command:

diagnose fmupdate view-serverlist fds

Note that (*) on 96.45.33.87 means this is the current active FDS server.

FortiManager will use the next available server, 173.243.138.92 if it fails to connect to 96.45.33.87.

Verify the connectivity using ping and a packet sniffer.

execute ping <current fds server>

execute ping fds1.fortinet.com

execute ping <the DNS server>

diagnose sniffer packet any “host <current fds server> and port 443”

Check the FDS connectivity log with the command below:

diagnose fmupdate view-linkd-log fds
