Current firmware cannot maintain active state on static route after reboot/power loss.
Static route is defined as on image below.
After power loss/restart status in below table is active but System Routing table not showing the route and route itself is not functioning.
To made it active and functioning, it is needed to deactivate and activate below route again.
Any investigation is needed. It it really anoyin when I cannot access home network throught tunnel becouse router was restarted or power loss leads to not active route.
