Possible DNS Resolver bug?
When you check "Enable Forwarding Mode" under DNS Resolver, save and apply, 127.0.0.1 drops off the list of DNS servers in the Dashboard. I assume that's normal?
However, when you uncheck "Enable Forwarding Mode" under DNS Resolver 127.0.0.1 doesn't reappear in the list of DNS servers.
Have replicated it on two different pfsense boxes, one running 2.3.b.20160116.1647 and the other 2.3.b.20160116.0804
already fixed: https://redmine.pfsense.org/issues/5775
Thanks, I should probably check redmine first before posting :)
