  • Overlay Controller VPN
  • FortiGuard Cloud-Assist SD-WAN Interface Bandwidth Monitoring l FortiManager Cloud l FortiAnalyzer Cloud

FortiGuard Security Rating Service

Not all FortiGate models can support running the FortiGuard Security Rating Service as a Fabric “root” device. The following FortiGate platforms can run the FortiGuard Security Rating Service when added to an existing Fortinet Security Fabric managed by a supported FortiGate model: l FGR-30D l FGR-35D l FGT-30E l FGT-30E-MI l FGT-30E-MN l FGT-50E l FGT-51E l FGT-52E

  • FWF-30E l FWF-30E-MI l FWF-30E-MN l FWF-50E l FWF-50E-2R l FWF-51E

Using FortiManager as a FortiGuard server

If you use FortiManager as a FortiGuard server, and you configure the FortiGate to use a secure connection to FortiManager, you must use HTTPS with port 8888. HTTPS with port 53 is not supported.

FortiGate 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 does 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.

 

CAPWAP traffic offloading

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. The following models are affected: l FG-900D l FG-1000D l FG-2000E l FG-2500E

FortiClient (Mac OS X) SSL VPN requirements

When using SSL VPN on Mac OS X 10.8, you must enable SSLv3 in FortiOS.

Use of dedicated management interfaces (mgmt1 and mgmt2)

Bug ID Description
584254 l Removed System > Advanced menu (moved most features to System > Settings page).

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

NP4lite platforms

FortiOS 6.2 and later does not support NP4lite platforms.

Tags option removed from GUI

The Tags option is removed from the GUI. This includes the following:

l The System > Tags page is removed. l The Tags section is removed from all pages that had a Tags section. l The Tags column is removed from all column selections.

System Advanced menu removal (combined with System Settings)

Bug ID Description
  l Moved configuration script upload feature to top menu > Configuration > Scripts page. l Removed GUI support for auto-script configuration (the feature is still supported in the CLI). l Converted all compliance tests to security rating tests.

l 1U platforms increased from 8 to 16 l 2U platforms increased from 32 to 64 l High-end platforms increased from 32 to 256

 

New features or enhancements

Bug ID Description
529445 In wids-profile, add the new ap-scan-threshold setting, which is the minimum signal level of rogue APs detected and required by the managed FortiAP devices. Only the rogue APs with a signal level higher than the threshold will be reported to the FortiGate WiFi Controller.

config wireless-controller wids-profile edit <WIDS-profile-name> set ap-scan enable set ap-scan-threshold “-80”

next

end

The range of ap-scan-threshold, in dBm, is -95 to -20 (default = -90).

553372 Under Administrative Access, CAPWAP and FortiTelemetry have been combined into one option labelled Fabric Connection. If either CAPWAP or FortiTelemetry were enabled on a particular interface, the new fabric option will be enabled after upgrading.
557614 FortiGate support for NSX-T v2.4: East/West traffic.
562394 Add support for EMS cloud:

l Added CMDB attribute fortinet-one-cloud-authentication to FortiClient EMS table. l Added curl verbose diagnosis debugs to FortiClient NAC daemon for debug images. l Added fortiems-cloud option to type attribute in user.fsso table.

571639 Add support for tracking number of hits to a policy route:

l  Policy route hit counter and last used tag added to each policy displayed in diagnose firewall proute list command.

l  New CLI command diagnose firewall proute show, displays policy route hit counter and last used for a given proute id, (if 0, dumps all).

l  New CLI command diagnose firewall proute clear, clears policy route hit counter and last used for a given proute id, (if 0, clears all).

573568 Change public IP and routing table entries allocated in different resource groups in Azure HA.

In an Azure HA scenario, the EIP and route table to fail over is specified in the SDN connector configuration. A new attribute, resource-group, is added to allow customers to specify the resource group that a EIP or route table is from. This new attribute can be empty so upgrade code is not needed.

If the resource-group of the EIP or route table is not provided, it is assumed the resource comes from the same resource group as the SDN connector setting (if it is not set there, assume the same resource group as the FortiGate itself by getting it from the instance metadata).

579484 Limit OCVPN spoke to only join existing overlay.
580889 DPDK support on FortiOS VM platform.

 

New features or enhancements

Bug ID Description
591567 Add support for additional SHA-2 algorithms with SNMPv3.
593148 Update interface-related pages to use AngularJS and muTable.

Interfaces list:

l  Radio buttons in the top-right corner let users switch between grouping by type, role, and sort lists alphabetically have been removed. There is a dropdown instead with the following options:

l  Group by type l Group by zone l Group by status, l Group by role l No grouping

l  Zones do not support parent-child relationships anymore.

l  The DHCP Server column has been divided into two separate columns, DHCP Clients and DHCP Ranges.

l  CSF support has been added. When switching to a downstream device, both the list and the faceplate should update.

l  For VDOMs, administrators can only view complete information about interfaces for the VDOM they are in. This applies even to administrators who have access to more than one VDOM.

l  On devices that support VLAN switching, the VLAN Switch Mode toggle has been removed from the list page. It now shows up under System> Settings.

l  Faceplates do not auto-refresh on page load anymore. For auto-refresh, users need to enable the muTable refresh feature from the button in the bottom-right corner.

Interfaces dialog:

l  Under Administrative Access, CAPWAP and FortiTelemetry have been combined into one option labelled Fabric Connection.

l  The secondary IP address toggle has been moved from the Miscellaneous section to the Address section.

l  A gutter has been added that displays the device hostname,the interface it belongs to, and relevant help links.

CLI changes:

l Consolidate fortitelemetry and capwap into fabric for allowaccess in system.interface.

  2. From the Download menu, select Firmware Images.
  3. Check that Select Product is FortiGate.
  4. Click the Upgrade Path tab and select the following:

l Current Product l Current FortiOS Version l Upgrade To FortiOS Version

  1. Click Go.

Device detection changes

In FortiOS 6.0.x, the device detection feature contains multiple sub-components, which are independent:

  • Visibility – Detected information is available for topology visibility and logging.
  • FortiClient endpoint compliance – Information learned from FortiClient can be used to enforce compliance of those endpoints.
  • Device-based policies – Device type/category and detected devices/device groups can be defined as custom devices, and then used in device-based policies.

In 6.2, these functionalities have changed:

  • Visibility – Configuration of the feature remains the same as FortiOS 6.0, including FortiClient information. l FortiClient endpoint compliance – A new fabric connector replaces this, and aligns it with all other endpoint connectors for dynamic policies. For more information, see Dynamic Policy FortiClient EMS (Connector) in the FortiOS 6.2.0 New Features Guide.
  • Mac-address-based policies – A new address type is introduced (Mac Address Range), which can be used in regular policies. The previous device policy feature can be achieved by manually defining MAC addresses, and then adding them to regular policy table in 6.2. For more information, see MAC Addressed-Based Policies in the FortiOS 6.2.0 New Features Guide.

If you were using device policies in 6.0.x, you will need to migrate these policies to the regular policy table manually after upgrade. After upgrading to 6.2.0:

  1. Create MAC-based firewall addresses for each device.
  2. Apply the addresses to regular IPv4 policy table.

FortiClient Endpoint Telemetry license

Starting with FortiOS 6.2.0, the FortiClient Endpoint Telemetry license is deprecated. The FortiClient Compliance profile under the Security Profiles menu has been removed as has the Enforce FortiClient Compliance Check option under each interface configuration page. Endpoints running FortiClient 6.2.0 now register only with FortiClient EMS 6.2.0 and compliance is accomplished through the use of Compliance Verification Rules configured on FortiClient EMS 6.2.0 and enforced through the use of firewall policies. As a result, there are two upgrade scenarios:

  • Customers using only a FortiGate device in FortiOS 6.0 to enforce compliance must install FortiClient EMS 6.2.0 and purchase a FortiClient Security Fabric Agent License for their FortiClient EMS installation.
  • Customers using both a FortiGate device in FortiOS 6.0 and FortiClient EMS running 6.0 for compliance enforcement, must upgrade the FortiGate device to FortiOS 6.2.0, FortiClient to 6.2.0, and FortiClient EMS to 6.2.0.

The FortiClient 6.2.0 for MS Windows standard installer and zip package containing FortiClient.msi and language transforms and the FortiClient 6.2.0 for macOS standard installer are included with FortiClient EMS 6.2.0.

Fortinet Security Fabric upgrade

FortiOS 6.2.3 greatly increases the interoperability between other Fortinet products. This includes:

  • FortiAnalyzer 6.2.3 l FortiClient EMS 6.2.0 l FortiClient 6.2.2 l FortiAP 5.4.4 and later l FortiSwitch 3.6.9 and later

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

If the Security Fabric is enabled, then all FortiGate devices must be upgraded to 6.2.3. When the Security Fabric is enabled in FortiOS 6.2.3, all FortiGate devices must be running FortiOS 6.2.3.

Minimum version of TLS services automatically changed

For improved security, FortiOS 6.2.3 uses the ssl-min-proto-version option (under config system global) to control the minimum SSL protocol version used in communication between FortiGate and third-party SSL and TLS services.

When you upgrade to FortiOS 6.2.3 and later, the default ssl-min-proto-version option is TLS v1.2. The following SSL and TLS services inherit global settings to use TLS v1.2 as the default. You can override these settings.

  • Email server (config system email-server) l Certificate (config vpn certificate setting) l FortiSandbox (config system fortisandbox)

 

  • FortiGuard (config log fortiguard setting) l FortiAnalyzer (config log fortianalyzer setting) l LDAP server (config user ldap) l POP3 server (config user pop3)

Downgrading to previous firmware versions

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

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

Amazon AWS enhanced networking compatibility issue

With this enhancement, there is a compatibility issue with 5.6.2 and older AWS VM versions. After downgrading a 6.2.3 image to a 5.6.2 or older version, network connectivity is lost. Since AWS does not provide console access, you cannot recover the downgraded image.

When downgrading from 6.2.3 to 5.6.2 or older versions, running the enhanced NIC driver is not allowed. The following AWS instances are affected:

X1 X1e z1d

A workaround is to stop the instance, change the type to a non-ENA driver NIC type, and continue with downgrading.

FortiLink access-profile setting

The new FortiLink local-access profile controls access to the physical interface of a FortiSwitch that is managed by FortiGate.

After upgrading FortiGate to 6.2.3, the interface allowaccess configuration on all managed FortiSwitches are overwritten by the default FortiGate local-access profile. You must manually add your protocols to the localaccess profile after upgrading to 6.2.3.

To configure local-access profile:

config switch-controller security-policy local-access edit [Policy Name] set mgmt-allowaccess https ping ssh set internal-allowaccess https ping ssh

next

end

To apply local-access profile to managed FortiSwitch:

config switch-controller managed-switch edit [FortiSwitch Serial Number] set switch-profile [Policy Name] set access-profile [Policy Name]

next

end

FortiGate VM with V-license

This version allows FortiGate VM with V-License to enable split-vdom.

To enable split-vdom:

config system global set vdom-mode [no-vdom | split vdom]

end
