I’m pulling my hair out over this. I’ve got a proxmox homelab, an LXC running technitium installed from TTeck’s script.

The DNS server is also doing DHCP for my network. I have an authoritative zone for ‘.lan’

I can get NS, SOA, TXT records from the DNS server, but no A records! The DNS query logs show that it gives an answer, and if I am on the DNS server itself I get an answer, but no other machines on the network hear the reply.

I think this means the DNS server is working properly. There are no FWs in the way as I can resolve other types.

Where else can I look, or how can I diagnose this? I am completely at a loss.

    How exactly are you testing this from your client, with ping? What are you using to query the DNS?

    If you run nslookup from the client

    • Does the ‘server’ command return the correct DNS server?
    • Does <A-record>.lan return the expected record?

    I’m assuming you’ve run ifconfig to verify your client’s NIC has been assigned the correct DNS via DHCP?

      Thanks for replying, I appreciate the response.

      I’m running dig @192.168.0.249 study.lan from my client (a MacBook).

      If I run ‘dig @192.168.0.249 study.lan TXT’ I get a correct response (I have added a txt record)

      If I run ‘dig @192.168.0.249 lan SOA’ or ‘NS’ I correctly get the records for the zone.

      I think this eliminates the possibility of it being a routing error?
