What’s new in FortiOS 5.6.3

For a list of new features and enhancements that have been made in FortiOS 5.6.3, see the What’s New for FortiOS 5.6.3 document.

Special Notices

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 and FortiWiFi-92D hardware limitation

FortiOS 5.4.0 reported an issue with the FG-92D model in the Special Notices > FG-92D High Availability in Interface Mode section of the release notes. Those issues, which were related to the use of port 1 through 14, include:

  • PPPoE failing, HA failing to form. l IPv6 packets being dropped. l FortiSwitch devices failing to be discovered. l Spanning tree loops may result depending on the network topology.

FG-92D and FWF-92D do not support STP. These issues have been improved in FortiOS 5.4.1, but with some side effects with the introduction of a new command, which is enabled by default:

config global set hw-switch-ether-filter <enable | disable>

When the command is enabled:

  • ARP (0x0806), IPv4 (0x0800), and VLAN (0x8100) packets are allowed. l BPDUs are dropped and therefore no STP loop results. l PPPoE packets are dropped. l IPv6 packets are dropped. l FortiSwitch devices are not discovered. l HA may fail to form depending the network topology.

When the command is disabled:

  • All packet types are allowed, but depending on the network topology, an STP loop may result.

FG-900D and FG-1000D

CAPWAP traffic will not offload if the ingress and egress traffic ports are on different NP6 chips. It will only offload if both ingress and egress ports belong to the same NP6 chip.

Special Notices

FortiGate-VM 5.6 for VMware ESXi

Upon upgrading to FortiOS 5.6.3, FortiGate-VM v5.6 for VMware ESXi (all models) no longer supports the VMXNET2 vNIC driver.

FortiClient profile changes

With introduction of the Security Fabric, FortiClient profiles will be updated on FortiGate. FortiClient profiles and FortiGate are now primarily used for Endpoint Compliance, and FortiClient Enterprise Management Server (EMS) is now used for FortiClient deployment and provisioning.

The FortiClient profile on FortiGate is for FortiClient features related to compliance, such as Antivirus, Web Filter, Vulnerability Scan, and Application Firewall. You may set the Non-Compliance Action setting to Block or Warn. FortiClient users can change their features locally to meet the FortiGate compliance criteria. You can also use FortiClient EMS to centrally provision endpoints. The EMS also includes support for additional features, such as VPN tunnels or other advanced options. For more information, see the FortiOS Handbook – Security Profiles.

Use of dedicated management interfaces (mgmt1 and mgmt2)

For optimum stability, use management ports (mgmt1 and mgmt2) for management traffic only. Do not use management ports for general user traffic.

FortiExtender support

Due to OpenSSL updates, FortiOS 5.6.3 cannot manage FortiExtender anymore. If you run FortiOS with FortiExtender, you must use a newer version of FortiExtender such as 3.2.1 or later.

Upgrade Information

Upgrading to FortiOS 5.6.3

FortiOS version 5.6.3 officially supports upgrading from version 5.4.5, 5.4.6, 5.6.0, 5.6.1, and 5.6.2. To upgrade from other versions, see Supported Upgrade Paths.

If you are upgrading from version 5.6.1 or 5.6.2, this caution does not apply.

Before upgrading, ensure that port 4433 is not used for admin-port or admin-sport (in config system global), or for SSL VPN (in config vpn ssl settings). If you are using port 4433, you must change admin-port, admin-sport, or the SSL VPN port to another port number before upgrading.

After upgrading, if FortiLink mode is enabled, you must manually create an explicit firewall policy to allow RADIUS traffic for 802.1x authentication from the FortiSwitch (such as from the FortiLink interface) to the RADIUS server through the FortiGate.

FortiGate-VM64-Azure upgrade

You can upgrade from the GUI or CLI. Because some configurations are not kept in the upgrade, we recommend you do a factory reset using execute factoryreset, and then reconfigure the VM.

Your original VM license is kept in the upgrade.

Security Fabric upgrade

FortiOS 5.6.3 greatly increases the interoperability between other Fortinet products. This includes:

l FortiAnalyzer 5.6.1 l FortiClient 5.6.0 l FortiClient EMS 1.2.2 l FortiAP 5.4.2 and later l FortiSwitch 3.6.2 and later

Upgrade the firmware of each product in the correct order. This maintains network connectivity without the need to use manual steps.

Before upgrading any product, you must read the FortiOS Security Fabric Upgrade Guide.


FortiClient profiles

After upgrading from FortiOS 5.4.0 to 5.4.1 and later, your FortiClient profiles will be changed to remove a number of options that are no longer supported. After upgrading, review your FortiClient profiles to make sure they are configured appropriately for your requirements and either modify them if required or create new ones.

The following FortiClient Profile features are no longer supported by FortiOS 5.4.1 and later:

  • Advanced FortiClient profiles (XML configuration).
  • Advanced configuration, such as configuring CA certificates, unregister option, FortiManager updates, dashboard Banner, client-based logging when on-net, and Single Sign-on Mobility Agent.
  • VPN provisioning. l Advanced AntiVirus settings, such as Scheduled Scan, Scan with FortiSandbox, and Excluded Paths. l Client-side web filtering when on-net. l iOS and Android configuration by using the FortiOS GUI.

With FortiOS 5.6.3, endpoints in the Security Fabric require FortiClient 5.6.0. You can use FortiClient 5.4.3 for VPN (IPsec VPN, or SSL VPN) connections to FortiOS 5.6.2, but not for Security Fabric functions.

FortiGate-VM 5.6 for VMware ESXi

Upon upgrading to FortiOS 5.6.3, FortiGate-VM v5.6 for VMware ESXi (all models) no longer supports the VMXNET2 vNIC driver.

Downgrading to previous firmware versions

Downgrading to previous firmware versions results in configuration loss on all models. Only the following settings are retained:

l operation mode l interface IP/management IP l static route table l DNS settings l VDOM parameters/settings l admin user account l session helpers l system access profiles


If you have long VDOM names, you must shorten the long VDOM names (maximum 11 characters) before downgrading:

  1. Back up your configuration.
  2. In the backup configuration, replace all long VDOM names with its corresponding short VDOM name.

For example, replace edit <long_vdom_name>/<short_name> with edit <short_name>/<short_ name>.

  1. Restore the configuration.
  2. Perform the downgrade.

Amazon AWS enhanced networking compatibility issue

With this new enhancement, there is a compatibility issue with older AWS VM versions. After downgrading a 5.6.3 image to an older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

When downgrading from 5.6.3 to older versions, running the enhanced nic driver is not allowed. The following AWS instances are affected:

  • C3 l C4 l R3
  • I2 l M4 l D2

SSL VPN host compatibility list

It is recommended to verify the accuracy of the GUID for the software you are using for SSL VPN host check. The following Knowledge Base article at describes how to identify the GUID for antivirus and firewall products: How to add non listed 3rd Party AntiVirus and Firewall product to the FortiGate SSL VPN Host check.

After verifying GUIDs, you can update GUIDs in FortiOS using this command:

config vpn ssl web host-check-software

Following is an example of how to update the GUID for AVG Internet Security 2017 on Windows 7 and Windows 10 by using the FortiOS CLI.

The GUIDs in this example are only for AVG Internet Security 2017 on Windows 7 and Windows 10. The GUIDs might be different for other versions of the software and other operation systems.

To update GUIDs in FortiOS:

  1. Use the config vpn ssl web host-check-software command to edit the AVG-InternetSecurity-AV variable to set the following GUID for AVG Internet Security 2017: 4D41356F-32AD-7C42-C820-63775EE4F413.
  2. Edit the AVG-Internet-Security-FW variable to set the following GUID:

Citrix XenServer limitations

The following limitations apply to Citrix XenServer installations:

  • XenTools installation is not supported.
  • FortiGate-VM can be imported or deployed in only the following three formats:
  • XVA (recommended)
  • VHD l OVF
  • The XVA format comes pre-configured with default configurations for VM name, virtual CPU, memory, and virtual NIC. Other formats will require manual configuration before the first power on process.

Open source XenServer limitations

When using Linux Ubuntu version 11.10, XenServer version 4.1.0, and libvir version 0.9.2, importing issues may arise when using the QCOW2 format and existing HDA issues.
