While Forti and its IPSEC is still in the works, I've posted short tutorial on how to get delayed hibernation working on every GNU/#Linux + SystemD based distro. https://sirmacik.net/delayed-hibernation-on-linux-with-systemd/?lang=en

@tadzik run systemctl status suspend.service
@tadzik and thanks, I've updated the post (:
