This guide provides release information for FortiOS 6.2.7 build 1190.
For FortiOS documentation, see the Fortinet Document Library.
Supported models
The following models are released on a special branch of FortiOS 6.2.7. To confirm that you are running the correct
build, run the CLI command get system status and check that the Branch point field shows 1190.
FortiOS 6.2.0 introduced several new cloud-based services listed below. The new services require updates to FortiCare
and Fortinet's FortiCloud single sign-on (SSO) service.
l Overlay Controller VPN
l FortiGuard Cloud-Assist SD-WAN Interface Bandwidth Monitoring
l FortiManager Cloud
l FortiAnalyzer Cloud
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
l FWF-30E
l FWF-30E-MI
l FWF-30E-MN
l FWF-50E
l FWF-50E-2R
l FWF-51E
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.
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:
l 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>
l 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.
l All packet types are allowed, but depending on the network topology, an STP loop may result.
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
When using SSL VPN on Mac OS X 10.8, you must enable SSLv3 in FortiOS.
For optimum stability, use management ports (mgmt1 and mgmt2) for management traffic only. Do not use management
ports for general user traffic.
NP4lite platforms
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.
Bug ID Description
459996 Samsung Galaxy Tab A 8 and Android 9.0 crash after L2TP over IPsec is connected.
Bug ID Description
605103 PCI passthrough ports order might be changed after upgrading. This does not affect VMXNET3 and
SR-IOV ports because SR-IOV ports are in MAC order by default.
SSL traffic over TLS 1.0 will not be checked and will be bypassed by
default
FortiOS 6.2.6 and 6.4.3 ended support for TLS 1.0 when strong-crypto is enabled under system global. With this
change, SSL traffic over TLS 1.0 will not be checked so it will be bypassed by default.
To examine and/or block TLS 1.0 traffic, an administrator can either:
l Disable strong-crypto under config system global. This applies to FortiOS 6.2.6 and 6.4.3, or later
versions.
l Under config firewall ssl-ssh-profile:
l in FortiOS 6.2.6 and later, set unsupported-ssl to block.
Bug ID Description
654032 The route-tag is a mechanism to map a BGP community string to a specific tag. The string may
correspond to a specific network that a BGP router advertised. With this tag, an SD-WAN service
rule can be used to define specific traffic handling to that network. IPv6 route tags are now
supported.
Supported upgrade path information is available on the Fortinet Customer Service & Support site.
1. Go to https://support.fortinet.com.
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
5. Click Go.
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:
l 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.
l 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.
FortiOS 6.2.7 greatly increases the interoperability between other Fortinet products. This includes:
l FortiAnalyzer 6.2.5
l FortiClient EMS 6.2.3 and later
l FortiClient 6.2.3 and later
l FortiAP 5.4.4 and later
l FortiSwitch 3.6.11 and later
When upgrading your Security Fabric, devices that manage other devices should be upgraded first. Upgrade the
firmware of each device in the following order. This maintains network connectivity without the need to use manual
steps.
1. FortiAnalyzer
2. FortiManager
3. FortiGate devices
4. Managed FortiSwitch devices
5. Managed FortiAP devices
6. FortiClient EMS
7. FortiClient
8. FortiSandbox
9. FortiMail
10. FortiWeb
11. FortiADC
12. FortiDDOS
13. FortiWLC
If the Security Fabric is enabled, then all FortiGate devices must be upgraded to 6.2.7. When
the Security Fabric is enabled in FortiOS 6.2.7, all FortiGate devices must be running FortiOS
6.2.7.
For improved security, FortiOS 6.2.7 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 6.2.7 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.
l Email server (config system email-server)
l Certificate (config vpn certificate setting)
l FortiSandbox (config system fortisandbox)
l 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 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 admin user account
l session helpers
l system access profiles
With this enhancement, there is a compatibility issue with 5.6.2 and older AWS VM versions. After downgrading a 6.2.7
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 6.2.7 to 5.6.2 or older versions, running the enhanced NIC driver is not allowed. The following
AWS instances are affected:
C5 Inf1 P3 T3a
C5d m4.16xlarge R4 u-6tb1.metal
C5n M5 R5 u-9tb1.metal
F1 M5a R5a u-12tb1.metal
G3 M5ad R5ad u-18tb1.metal
G4 M5d R5d u-24tb1.metal
H1 M5dn R5dn X1
I3 M5n R5n X1e
I3en P2 T3 z1d
A workaround is to stop the instance, change the type to a non-ENA driver NIC type, and continue with downgrading.
The new FortiLink local-access profile controls access to the physical interface of a FortiSwitch that is managed by
FortiGate.
After upgrading FortiGate to 6.2.7, 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 local-
access profile after upgrading to 6.2.7.
To enable split-vdom:
