Description

If I use the default Outgoing Interface setting for Unbound (ALL), the DNS Resolver does not really use all interfaces but follows the IPV4/6 default routes for queries. So if the deafult route switches, Unbound uses the new one.
If I select WAN1 and WAN2 as outgoing interfaces, Unbound uses both simultaneously. If one of those interfaces gateways goes down, Unbound does still use that interface for queries and they fail.
So it would be great if Unbound were able to use a loadbalancing Gateway Group (all interfaces in that group as outgoing) and in case of one gateway going down, remove that interface from unbound.conf.
