When the auto-firmware-upgrade setting is enabled, the FortiGate checks for updates every day between the firmware upgrade time interval. When a newer firmware is found, the installation is scheduled after the upgrade delay in days (0-14, default = 3) between the firmware upgrade time interval. After a successful update, an email is sent to the account owner.

config system fortiguard
    set auto-firmware-upgrade {enable | disable}
    set auto-firmware-upgrade-delay <integer>
end

Where:

• auto-firmware-upgrade is enabled by default upon upgrade.

• auto-firmware-upgrade-delay is set to 3 days by default.

Affected platforms:

If a DHCP Interface is added as an SD-WAN Member inside an SD-WAN zone, before config static route on SD-WAN zone, FortiOS by default adds a default route with dhcp interface distance in the routing table using the gateway IP information retrieved from the DHCP server. This default route will take precedence over other default routes that have a higher AD.
