Hi,
Could please somebody explain how exactly a combination of OSPF routes from WAN interfaces and rules from outbound policies are working together ? As I see now (BR2 Pro, 8.5.0), as soon as default route is received via OSPF on WAN interface - router start ignoring all outbound policies and sends all traffic using OSPF default route only.
The problem I’m trying to solve - use router’s own connectivity to Internet (for example, Starlink, cellular and so on) as long as possible, but when this connectivity finally fail - route all traffic via some “last resort gateway”. There could be several “last resort gateways” with different IP addresses behind the same WAN interface. That’s why I can’t use static default gateway and trying to play with OSPF.
I’m quite new to Peplink equipment and that’s why I have a strong feeling that I may miss some core concepts while trying to use approach from, let’s say, Cisco world 
So any help is really appreciated.
