      I have a pfSense setup with following configuration related to the problem I have:

      • Unbound used as DNS resolver
      • pfBlockerNG installed, active and set in python mode
      • Firewall rules to redirect client DNS queries to pfSense (i.e. no bypass allowed)
      • pfSense connected to a modem via PPPoE (legacy driver in use)

      I happily used pfSense set with internal DNS resolution as primary and back off to external DNS resolver (default setting), but since a while (I can't track down if happened across a version change or a setting change) it happens pfSense stops resolving DNS queries leading to websites being unreachable.

      If I restart unbound service it starts working again for 3-4h, then it happens again.
      If I set unbound in forwarding mode and pfSense general config to ignore local DNS resolution everything works fine for weeks.

      I inspected unbound logs but without any luck (maybe due to limited understanding) finding nothing suspicious.

      pfSense is plus version, running on a VM in proxmox.

      Can anyone have any hints of what is going on or can suggest further info I can provide/search to understand the issue?
