Configure SD-WAN for RBVPN instead of Static Routing but not working

You could give us some screenshot, so we can try to help. 

Luckily just after posting in community I received a call and the person after 2-3 hrs of time was able to resolve. 

I am also struggling to find information on this combination of SD-WAN and RBVPN.  The RBVPN documentation just shows Static Route examples.  The SD-WAN documentation just shows Site-to-Site VPN examples.  Need the two combined.  Anyone know if there is a Sophos example of this I haven't found?

Can you mentioned as you have achieved till the configuration you have done. Please share screenshot or provide details accordingly I can help you.
