      I currently have a network setup in the following manner:

      VLAN101: 192.168.30.0/24
      VLAN102: 192.168.40.0/24
      

      Each VLAN uses the virtual IP of the firewall as their gateway (and for DNS):

      VLAN101: 192.168.30.1
      VLAN102: 192.168.40.1
      

      I am also using pfBlockerNG with a DNSBL IP address (accessible from all VLANs) to sinkhole ad domains:

      DNSBL: 10.10.10.1
      

      When I resolve firewall.lan from any of the VLANs, I receive the DNSBL IP address of 10.10.10.1, however when resolving firewall.lan from each of the VLANs I want to receive the current gateway IP address of that VLAN.

      So, what I want to achieve is for example when resolving firewall.lan from VLAN101 I would receive the IP address of 192.168.30.1.

      I have attempted to solve this problem using unbound views, for example:

      server:
      access-control-view: 192.168.30.0/24 test
      view:
      name: "test"
      local-zone: "lan" inform
      local-data: "firewall.lan. 90 IN A 192.168.30.1"
      

      Which works as expected, however after setting this view I can no longer resolve any other hosts on the subnet.

      I can only resolve firewall.lan, but no longer resolve any other host on 192.168.30.0/24 (such as nas.lan).

      Can somebody assist me to fix this issue?

      Is there a way to configure the unbound view to otherwise pass the request through so I can use the specific view, but also the dynamically registered users from dhcp?

      Thanks in advance
