Hyperscale incompatibilities and limitations

See Hyperscale firewall incompatibilities and limitations in the Hyperscale Firewall Guide for a list of limitations and incompatibilities with FortiOS 7.4.3 features.

FortiGate 6000 and 7000 incompatibilities and limitations

See the following links for information about FortiGate 6000 and 7000 limitations and incompatibilities with FortiOS 7.4.3 features.

• FortiGate 6000 incompatibilities and limitations
• FortiGate 7000E incompatibilities and limitations
• FortiGate 7000F incompatibilities and limitations

Remove OCVPN support
The IPsec-based OCVPN service has been discontinued and licenses for it can no longer be purchased as of FortiOS 7.4.0. GUI, CLI, and license verification support for OCVPN has been removed from FortiOS. Upon upgrade, all IPse phase 1 and phase 2 configurations, firewall policies, and routing configuration previously generated by the OCVPN service will remain. Alternative solutions for OCVPN are the Fabric Overlay Orchestrator in FortiOS 7.2.4 and later, and the SD-WAN overlay templates in FortiManager 7.2.0 and later.

• Remove WTP profiles for older FortiAP models| Support for WTP profiles has been removed for FortiAP B, C, and D series models, and FortiAP-S models in FortiOS 7.4.0 and later. These models can no longer be managed or configured by the FortiGate wireless controller. When one of these models tries to discover the FortiGate, the FortiGate’s event log includes a message that the FortiGate’s wireless controller can not be managed because it is not supported.

• IP pools and VIPs are now considered local addresses

• In FortiOS 7.4.1 and later, all IP addresses used as IP pools and VIPs are now considered local IP addresses if
  responding to ARP requests on these external IP addresses is enabled (set arp- reply enable, by default). For these cases, the FortiGate is considered a destination for those IP addresses and can receive reply traffic at the
  application layer.
  Previously in FortiOS 7.4.0, this was not the case. For details on the history of the behavior changes for IP pools and VIPs, and for issues and their workarounds for the affected FortiOS versions, see

• Technical Tip: IP pool and virtual IP behavior changes in FortiOS 6.4, 7.0, 7.2, and 7.4.

• Remove support for SHA-1 certificate used for web management interface (GUI)

• In FortiOS 7.4.0 and later, users should use the built-in Fortinet_GUI_Server certificate or SHA-256 and higher certificates for the web management interface. For example:
  config system global set admin-server-cert Fortinet_GUI_Server end

Number of configurable DDNS entries

• Starting in FortiOS 7.4.0, the number of DDNS entries that can be configured is restricted by table size. The limits are 16, 32, and 64 entries for lentry-level, mid-range, and high-end FortiGate models respectively.
• After upgrading to FortiOS 7.4.0 or later, any already configured DDNS entries that exceed the limit for the FortiGate model in use will be deleted. For example, if a user has 20 DDNS entries before upgrading to 7.4.0 and is using a entry-level FortiGate model, the last four DDNS entries will be deleted after upgrading.
• In such instances where the number of DDNS entries exceeds the supported limit for the FortiGate model in use, users have the option to upgrade their FortiGate model to one that supports a higher number of DDNS entries.

FortiGate models with 2 GB RAM can be a Security Fabric root

• A Security Fabric topology is a tree topology consisting of a FortiGate root device and downstream devices within the mid-tier part of the tree or downstream (leaf) devices at the lowest point of the tree.
• As part of improvements to reducing memory usage on FortiGate models with 2 GB RAM, FortiOS 7.4.2 and later can authorize up to five devices when serving as a Fabric root.
• The affected models are the FortiGate 40F, 60E, 60F, 80E, and 90E series devices and their variants.
• To confirm if your FortiGate model has 2 GB RAM, enter diagnose hardware sysinfo conservein the CLI and check that the total RAM value is below 2000 MB (1000 MB = 1 GB).

Admin and superadmin administrators cannot log in after a prof admin VDOM administrator restores the VDOM configuration and reboots the FortiGate

• When a VDOM administrator using the prof_admin profile is used to restore a VDOM configuration and then reboot the FortiGate, an administrator using the super_admin profile (including the default admin administrator) cannot log in to the FortiGate.
• Therefore, in FortiOS 7.4.1, a prof_admin VDOM administrator should not be used to restore a VDOM configuration
• (FortiOS 7.4.2 and later are not affected).

Workarounds:

1. If a prof_admin VDOM administrator has already been used to restore a VDOM configuration, then do not reboot. Instead, log in using a super_admin administrator (such as default admin), back up the full configuration, and restore the full configuration. After the full configuration restore and reboot, super_admin administrators will continue to have the ability to log into the FortiGate.|After this workaround is done, the FortiGate is still susceptible to the issue if the backup and restore is performed again by the prof_admin VDOM administrator. A FortiOS firmware upgrade with this issue resolved will be required to fully resolve this issue.
2. To recover super_admin access after having restored a VDOM configuration and performing a FortiGate reboot, power off the device and boot up the FortiGate from the backup partition using console access.

SMB drive mapping with ZTNA access proxy

• In FortiOS 7.4.1 and later, SMB drive mapping on a Windows PC made through a ZTNA access proxy becomes inaccessible after the PC reboots when access proxy with TCP forwarding is configured as FQDN. When configured with an IP for SMB traffic, same issue is not observed.
• One way to solve the issue is to enter the credentials into Windows Credential Manager in the form of domain\username.
• Another way to solve the issue is to leverage the KDC proxy to issue a TGT (Kerberos) ticket for the remote user. See ZTNA access proxy with KDC to access shared drives for more information. This  way, there is no reply in Credential Manager anymore, and the user is authenticated against the DC.

Remote access with write rights through FortiGate Cloud

• Remote access with read and write rights through FortiGate Cloud now requires a paid FortiGate Cloud subscription. The FortiGate can still be accessed in a read-only state with the free tier of
• FortiGate Cloud. Alternatively, you can access your FortiGate through its web interface.
• Please contact your Fortinet Sales/Partner for details on purchasing a FortiGate Cloud Service subscription license for your FortiGate device.
• For more information see the FortiGate Cloud feature comparison and FortiGate Cloud Administration guide FAQ.

FortiGuard Web Filtering Category v10 update

• Fortinet has updated its web filtering categories to v10, which includes two new URL categories for AI chat and cryptocurrency websites. To use the new categories, customers must upgrade their Fortinet products to one of the versions below:
  • FortiManager – Fixed in 6.0.12, 6.2.9, 6.4.7, 7.0.2, 7.2.0, 7.4.0.
  • FortiOS – Fixed in 7.2.7 and 7.4.1.
  • FortiClient – Fixed in Windows 7.2.3, macOS 7.2.3, Linux 7.2.3.
  • FortiClient EMS – Fixed in 7.2.1.
  • FortiMail – Fixed in 7.0.7, 7.2.5, 7.4.1.
  • FortiProxy – Fixed in 7.4.1.
• Please read the following CSB for more information to caveats on the usage in FortiManager and FortiOS: https://support.fortinet.com/Information/Bulletin.aspx

FortiAP-W2 models may experience bootup failure during automatic firmware and federated upgrade process if they are powered by a managed FortiSwitch’s PoE port

• Disable automatic firmware upgrades and the federated upgrade feature if you have FortiAP-W2 devices that are exclusively powered by a PoE port from a FortiGate or FortiSwitch.
• The federated upgrade feature starts the upgrades of managed FortiSwitch and FortiAP devices start at approximately the same time. Some FortiAP-W2 devices take a longer time to upgrade than the
• FortiSwitch devices. When the FortiSwitch finishes upgrading, it reboots, and can disrupt the PoE power to the FortiAP devices. If a FortiAP device is still upgrading when the power is disrupted, it can cause the FortiAP device to experience a bootup failure.
• Both automatic firmware upgrade and manually triggering federated upgrade can cause this issue.
• For more information about federated upgrade and automatic firmware upgrades, see Upgrading all device firmware by following the upgrade path (federated update) and Enabling automatic firmware updates.
• To disable automatic upgrade:
• config system fortiguard set auto-firmware-upgrade disable end

CLI system permissions

• Starting in FortiOS 7.4.2, the usage of CLI diagnostic commands (cli-diagnose), previously named system-
  diagnostics, is disabled by default, with the exception of super_admin profile users. Users can now exercise more granular control over the CLI commands. See CLI system permissions for more information.

• When the user upgrades to FortiOS 7.4.2 or later, the following settings for CLI options will be applied, irrespective of whether system-diagnosticswas enabled or disabled in FortiOS 7.4.1 or earlier.

• To enable permission to run CLI diagnostic commands after upgrading: config system accprofile edit set cli-diagnose enable next end
• Many diagnostic commands have privileged access. As a result, using them could unintentionally grant unexpected access or cause serious problems, so understanding the risks involved is crucial.

Fortinet Security Fabric upgrade

FortiOS 7.4.3 greatly increases the interoperability between other Fortinet products. This includes:

• 2.3.3 and later for post-transfer scanning

• 4.2.0 and later for post-transfer and inline scanning

• If you are using FortiClient only for IPsec VPN or SSL VPN, FortiClient version 6.0 and later are supported. When upgrading your Security Fabric, devices that manage other devices should be upgraded first.
  When using FortiClient with FortiAnalyzer, you should upgrade both to their latest versions. The versions between the two products should match. For example, if using FortiAnalyzer 7.4.0, use FortiClient 7.4.0.
  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. Managed FortiExtender devices
  4.  FortiGate devices
  5. Managed FortiSwitch devices
  6. Managed FortiAP devices
  7.  FortiClient EMS
  8. FortiClient
  9.  FortiSandbox
  10.  FortiMail
  11.  FortiWeb
  12.  FortiNAC
  13.  FortiVoice
  14. FortiDeceptor
  15. FortiNDR
  16.  FortiTester
  17.  FortiMonitor
  18.  FortiPolicy

If Security Fabric is enabled, then all FortiGate devices must be upgraded to 7.4.3. When Security Fabric is enabled in FortiOS 7.4.3, all FortiGate devices must be running FortiOS 7.4.3.

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

After logging in, go to Support > Firmware Image Checksums (in the Downloads section), enter the image file name including the extension, and click Get Checksum Code.

FortiGate 6000 and 7000 upgrade information

• Upgrade FortiGate 6000 firmware from the management board GUI or CLI. Upgrade FortiGate 7000 firmware from the primary FIM GUI or CLI. The FortiGate 6000 management board and FPCs or the FortiGate 7000 FIMs and FPMs all run the same firmware image. Upgrading the firmware copies the firmware image to all components, which then install the new firmware and restart. A FortiGate 6000 or 7000 firmware upgrade can take a few minutes, the amount of time depending on the hardware and software configuration and whether DP or NP7 processor software is also upgraded.
• On a standalone FortiGate 6000 or 7000, or an HA cluster with uninterruptible-upgradedisabled, the firmware upgrade interrupts traffic because all components upgrade in one step. These firmware \ upgrades should be done during a quiet time because traffic can be interrupted for a few minutes during the upgrade process.
• Fortinet recommends running a graceful firmware upgrade of a FortiGate 6000 or 7000 FGCP HA cluster by enabling uninterruptible-upgradeand session-pickup. A graceful firmware upgrade only causes minimal traffic interruption.
  • Fortinet recommends that you review the services provided by your FortiGate 6000 or 7000 before a firmware upgrade and then again after the upgrade to make sure that these services continue to operate normally. For example, you might want to verify that you can successfully access an important server used by your organization before the upgrade and make sure that you can still reach the server after the upgrade and performance is comparable. You can also take a snapshot of key performance indicators (for example, number of sessions, CPU usage, and memory usage) before the upgrade and verify that you see comparable performance after the upgrade.

To perform a graceful upgrade of your FortiGate 6000 or 7000 to FortiOS 7.4.3:

1. Use the following command to set the upgrade-mode to uninterruptible support HA graceful upgrade:

   • config system ha
     set uninterruptible-upgrade enable end

   • When upgrading from FortiOS 7.4.1 to a later version, use the following command to enable uninterruptible upgrade:
     config system ha

   • set upgrade-mode uninterruptible end

2. Download the FortiOS 7.4.3 FG-6000F, FG-7000E, or FG-7000F firmware from https://support.fortinet.com.

3. Perform a normal upgrade of your HA cluster using the downloaded firmware image file.

4. When the upgrade is complete, verify that you have installed the correct firmware version.
   For example, check the FortiGate dashboard or use the get system statuscommand.

5. Confirm that all components are synchronized and operating normally.
   For example, go to Monitor > Configuration Sync Monitor to view the status of all components, or use diagnose sys confsync statusto confirm that all components are synchronized.

IPS-based and voipd-based VoIP profiles

• In FortiOS 7.4.0 and later, the new IPS-based VoIP profile allows flow-based SIP to complement SIP ALG while working together. There are now two types of VoIP profiles that can be configured:
  config voip profile

• edit set feature-set {ips | voipd} next end

• A voipd-based VoIP profile is handled by the voipd daemon using SIP ALG inspection. This is renamed from proxy in previous FortiOS versions.

• An ips-based VoIP profile is handled by the IPS daemon using flow-based SIP inspection. This is renamed from flow i   previous FortiOS versions.
  Both VoIP profile types can be configured at the same time on a firewall policy. For example: config firewall policy edit 1 set voip-profile “voip_sip_alg” set ips-voip-filter “voip_sip_ips” next end

• Where:

  • voip-profile can select a voip-profile with feature-set voipd.
  • ips-voip-filter can select a voip-profile with feature-set ips.

• The VoIP profile selection within a firewall policy is restored to pre-7.0 behavior. The VoIP profile can be selected regardless of the inspection mode used in the firewall policy. The new ips-voip-filter setting allows users to select an IPS-based VoIP profile to apply flow-based SIP inspection, which can work concurrently with SIP ALG.

• Upon upgrade, the feature-set setting of the voip profile determines whether the profile applied in the firewall policy is voip-profile or ips-voip-filter

BIOS-level signature and file integrity checking during downgrade

When downgrading to a version of FortiOS prior to 6.4.13, 7.0.12, and 7.2.5 that does not support BIOS-level signature and file integrity check during bootup, the following steps should be taken if the BIOS version of the FortiGate matches the following versions:

• 6000100 or greater
• 5000100 or greater

To downgrade or upgrade to or from a version that does not support BIOS-level signature and file integrity check during bootup:

1. If the current security level is 2, change the security level to 0. This issue does not affect security level 1 or below.
2. Downgrade to the desired FortiOS firmware version.
3. If upgrading back to 6.4.13, 7.0.12, 7.2.5, 7.4.0, or later, ensure that the security level is set to 0.
4. Upgrade to the desired FortiOS firmware version.
5. Change the security level back to 2.

To verify the BIOS version:

• The BIOS version is displayed during bootup:
• Please stand by while rebooting the system. Restarting system
• FortiGate-1001F (13:13-05.16.2023)
