[ckarwei]

Description

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

Anti virus updates will be used as example.

Solution

Terminology used in this document:
FDS= AV/IPS service
FGD = WF/AS service
AV= Anti-Virus
IPS= Intrusion Prevention System
WF= Web-Filtering
AS= Anti-Spam

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

2) Ensure that FortiGuard communication is enable.

AntiVirus and IPS Service needs to be 'ON' and FortiGate/FortiMail/FotiSandbox/FortiClient/FortiSwitch version has to be checked.

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

Manage unit will not able to get the update if it is not enable.

4) Check the FDS server list.

From CLI, use the command below:

# 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

5) Verify the connectivity using packet sniffer.

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

6) Check the FDS connectivity log with the command below:

# diagnose fmupdate view-linkd-log fds
