Affected models

Model Part Number
FWF-60CX-ADSL PN: 8918-04 and later

The following units have a memory compatibility issue with FortiOS 5.2.1 and lower. It is recommended to use FortiOS 5.2.2 and later for these units.

FG-600C-DC PN: 10743-08 and later
FG-600C-LENC PN: 11317-07 and later

Removed WANOPT, NETSCAN, FEXP features from USB-A

The following features have been removed from the FortiGate and FortiWiFi 80C, 80CM, and 81CM:

  • WAN Optimization
  • Vulnerability scanning
  • Using FortiExplorer on a smartphone to manage the device by connecting to the USB-A port

Router Prefix Sanity Check

Prior to FortiOS 5.2.4 under the config router prefix table, if there are any le and ge settings that have the same prefix length as the prefix, you may lose the prefix rule after upgrading to FortiOS 5.2.4 or later.

WAN Optimization in FortiOS 5.2.4

In FortiOS 5.2.4:

  • If your FortiGate does not have a hard disk, WAN Optimization is not available.
  • If your FortiGate has a hard disk, you can configure WAN Optimization from the CLI.
  • If your FortiGate has two hard disks, you can configure WAN Optimization from the GUI.

See the FortiOS 5.2.4 Feature Platform Matrix to check the availability for your FortiGate model.

Built-In Certificate

FortiGate and FortiWiFi D-series and above have a built in Fortinet_Factory certificate that uses a 2048-bit certificate with the 14 DH group.

FortiGate-92D High Availability in Interface Mode

The FortiGate-92D may fail to form an HA cluster and experience a spanning tree loop if it is configured with the following:

  • operating in interface mode
  • at least one of the interfaces, for example interface9, is used has the HA heartbeat interface
  • a second interface is connected to an external switch

Workaround: use either WAN1 or WAN2 as the HA heartbeat device.

Default log setting change

For FG-5000 blades and FG-3900 series, log disk is disabled by default. It can only be enabled via CLI. For all 2U & 3U models (FG-3600/FG-3700/FG-3800), log disk is also disabled by default. For all 1U models and desktop models that supports SATA disk, log disk is enabled by default.

FG-5001D operating in FortiController or Dual FortiController mode

When upgrading a FG-5001D operating in FortiController or dual FortiController mode from version 5.0.7 (B4625) to FortiOS version 5.2.3, you may experience a back-plane interface connection issue. This is due to a change to the ELBC interface mapping ID. After the upgrade, you will need to perform a factory reset and then re-configure the device.

FortiGate units running 5.2.10

FortiGate units running 5.2.10 and managed by FortiManager 5.0.0 or 5.2.0 may report installation failures on newly created VDOMs, or after a factory reset of the FortiGate unit even after a retrieve and re-import policy.

For the latest information, see the FortiManagerand FortiOS Compatibility.

Firewall services

Downgrading from 5.2.3 to 5.2.2 may cause the default protocol number in the firewall services to change. Double check your configuration after downgrading to 5.2.2.

FortiPresence

For FortiPresence users, it is recommended to change the FortiGate web administration TLS version in order to allow the connection.

config system global set admin-https-ssl-versions tlsv1-0 tlsv1-1 tlsv1-2

end

SSL VPN setting page

The default server certificate has been changed to the Fortinet_Factory option. This excludes FortiGateVMs which remain at the self-signed option. For details on importing a CA signed certificate, please see the How to purchase and import a signed SSL certificate document.
