SDWAN Routing not working with/after Static Routes

IanR999

I have got 2 Sophos FW Home firewalls (Home, and In-laws) running V20.0.0 with a red-link working between them.

This link has historically been Static Routes at each end and has worked perfectly but we want to separate some traffic so I have tried to move over to SDWAN Routing.

Whenever I created the SD-WAN routes according to workflows, the routers have all failed to send any traffic across (I thought I was missing something).

In my numerous attempts to get this working, I managed to create a SD-WAN rule that bricked all communications in and out of one of the two routers, and the only (And quickest) solution was to do a factory reset.

I decided as part of reconfiguration to only do the SD-WAN routing and not touch static routes, and magically they are working on that router..

If I replicate the config on the other router (not been reset (yet)) then it just breaks all traffic, even after a reboot.

I have already set routing order preference to SD_WAN, Static, VPN so the SD_WAN should take priority, but it just doesn't seem to do anything.

Am I missing something? 

Thanks

Ian

    Interestingly, if the SD-WAN route is there, AND the static route is there, traffic does flow across the link and I get a ping response from each end (I have assumed this is using the static route), but, the SD-WAN traffic counters do increase at the same time.

    I have also checked route -n and the route is not in there, but the another (unrelated) static route is showing in there.
