On the System > FortiGuard page, the override FortiGuard server for AntiVirus & IPS Updates shows an Unknown status, even if the server is working correctly. This is a display issue only; the override feature is working properly.

On the Network > Interfaces page when VDOM mode is enabled, the Global view incorrectly shows the status of IPsec tunnel interfaces from non-management VDOMs as up. The VDOM view shows the correct status.

On the Policy & Objects > Firewall Policy page, the policy list can take around 30 seconds or more to load when there is a large number (over 20 thousand) of policies.

Workaround: use the CLI to configure policies.

System > Certificates list sometimes shows an incorrect reference count for a certificate, and incorrectly allows a user to delete a referenced certificate. The deletion will fail even though a success message is shown. Users should be able to delete the certificate after all references are removed.

When using the SSL VPN web portal in the Firefox, users cannot paste text into the SSH terminal emulator.

Workaround: use Chrome, Edge, or Safari as the browser.

When a FortiGate is managed by FortiManager with FortiWLM configured, the HTTPS daemon may crash while processing some FortiWLM API requests. There is no apparent impact on the GUI operation.

On a mobile phone, the WiFi captive portal may take longer to load when the default firewall authentication login template is used and the user authentication type is set to HTTP.

Workaround: edit the login template to disable HTTP authentication or remove the href link to googleapis.

The Device Inventory widget shows no results when there are two user_info parameters.

Workaround: use the CLI to retrieve the device list.

On the Network > Interfaces page, users cannot modify the TFTP server setting. A warning with the message This option may not function correctly. It is already configured using the CLI attribute: tftp-server. appears beside the DHCP Options entry.

Workaround: use the CLI.

When upgrade firmware from 7.0.1 to 7.0.2, the GUI incorrectly displays a warning saying this is not a valid upgrade path.

FortiOS 7.0 has new design for dialup VPN (no more route tree in the IPsec tunnel), so traffic might not traverse over the dialup IPsec VPN after upgrading from FortiOS 6.4.6 to 7.0.1, 7.0.2, or 7.0.3 if the server replies on the static route over the dynamic tunnel interface to route the traffic back to the client.

Workaround: configure the src-subnet on the client phase 2 interface. Then, static routes will be added by IKE on the server side (add-route enable is required).

config vpn ipsec phase2-interface
    edit <name>
        set src-subnet <x.x.x.x/x>
    next
end

IPsec aggregate static route is not marked inactive if the IPsec aggregate is down.

An error case occurs in WAD while handling the HTTP requests for an explicit proxy policy.

After the Chrome 92 update, in FOS 6.2, 6.4, or 7.0 running an IPS engine older than version 5.00246, 6.00099, or 7.00034, users are unable to reach specific websites in proxy mode with UTM applied. In flow mode everything works as expected.

DTLS does not work for SSL VPN and switches to TLS.

A large number of detected devices causes httpsd to consume resources, and causes entry-level devices to enter conserve mode.

A DNS proxy crash occurs during ssl_ctx_free.

Random LTE modem disconnections due to certain carriers getting unstable due to WWAN modem USB speed under super-speed.

Packet loss on the LAG interface (eight ports) using SFP+/SFP28 ports in both static and active mode. Affected models: FG-110xE, FG-220xE, and FG-330xE.

The value of the extra-init parameter under config system lte-modem is not passed to the modem after rebooting the device.

High CPU usage on platforms with low free memory upon IPS engine initialization.

On FG-100F, no event is raised for PSU failure and the diagnostic command is not available.

DST_Root_CA_X3 certificate is expired.
