Hello team,
im designing some contingency plans for our Umbrella service. all the client devices on our organization currently use our 2 VAs as DNS. I want, in the case they lose connection to OpenDNS Cloud (has happened once, route to OpenDNS was lost on our ISP), forward the DNS resolution for non-internal domains to the internal DNS servers. I was thinking something like Domain Management > *.* -- so every domain is internally forwarded.
Umbrella VA is not very customizable in terms of behaviour, so I wanted to discuss with yo uall if this is something that would work; or if you have a better suggestion to improved redundancy on the deployment.
