Description

Expected behavior:
If we have host override in pfSense "DNS resolver", pfSense should never ever return public IP for overriden host.

Actual behavior:
Sometimes pfSense returns external IP of overriden host in additional section of reply to MX-type query (i.e. Unbound do not respect own host overrides when inserts additional info in replies). May be it's Unbound's bug.

How to solve:
Add "minimal-responses: yes" to default Unbound config and prevent Unbount from returning additional info in replies.
