Microsoft Windows updates related to CPU security flaw (Meltdown)

Microsoft Windows updates may not occur due to a CPU security flaw (Meltdown) with anti-virus products installed. Please read the customer service bulletin CSB-180105-1 at https://support.fortinet.com/Information/Bulletin.aspx. A PDF of the bulletin can be downloaded from the firmware download directory of the Fortinet support site at https://support.fortinet.com.

Nested VPN tunnels

Parallel, independent VPN connections to different sites are not supported; however, FortiClient VPN connection may still be established over existing third-party (for example, AT&T Client) VPN connection (nested tunnels).

SSL VPN 98% issues

The new SSL VPN Windows driver, which was first introduced in FortiClient 5.6.0, resolves various SSL VPN connection issues. The new driver will help increase performance by up to 20% and provide a stable VPN connection.

Latency or poor network connectivity can affect the FortiClient SSL VPN connection. To further help avoid timeouts, the login timeout on the FortiGate can be increased to 180 seconds using the following CLI command:

configure vpl ssl settings

set log-in timeout 180

Windows notification of AV being disabled

In FortiClient 6.0.2, FortiClient will notify Windows Security Center Antivirus is Down only when FortiClient Antivirus has really stopped running.

Local certificate store not supported

FortiClient (Windows) no longer supports the local certificate store, and it is recommended you use Windows Certificates Store instead. If you are currently using the local certificate store, you should transition to Windows Certificates Store before upgrading to FortiClient (Windows) 6.0.2.

Microsoft Windows server support

For Microsoft Windows servers, the AntiVirus and Vulnerability Scan features for FortiClient are supported.

Rebranding tool not supported

FortiClient (Windows) 6.0.2 does not support the FortiClient Rebranding Tool.
