DNS not working with gateway group (setup for failureover)

[driv3l]

I have a gateway group setup viz. WAN0, and WAN1.

The problem I noticed was that when WAN0 went down, DNS started failing. After much searching, the recommendations to fix this is to modify the default LAN rule and set the gateway to be the gateway group (from the default).

However, when I change the gateway for the default lan group, all DNS starts failing immediately (although traffic still seems to be working if the address has already been resolved).

Even if I set the default gateway to WAN0 for the rule (which is the default anyways), DNS still starts failing immediately.


Anyone have any ideas how to resolve this (or another option for getting DNS to work when WAN0 goes down)?

Note, I am using the resolver and not forwarding to any DNS servers.
