      I've read a lot of posts about DNS not failing over on Multi-WAN but I think I'm having the opposite issue. This is related to my post here. I have failover groups between a Cable link and a DSL link, with Cable being the primary. Somehow, even when still on Cable, DNS requests go out both the Cable and DSL. It doesn't matter that I mark the DSL Gateway as down, DNS still goes out both links. Shouldn't DNS queries go out whichever gateway is in use? I've looked at the packets going out and it's only DNS. I don't have to worry about DNS not failing over. It's always running on both links and I don't know why. The only way I can keep things up and running how is to just disable the DSL port on the firewall. Any help would be appreciated.

        If it makes any difference, I have Unbound in Resolver mode. I specified the Network Interfaces and Outgoing Network Interfaces. After disabling the DSL interface (OPT1WAN2), changing those 2 interface settings to both read "ALL", and re-enabling the interface the problem seems to have stopped. I'll check again in the morning but that seems...odd...to me.
