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.

Thanks for the suggestion, I’ll grab a cap to check.
I’m running
tcpdump -i any port 53. I can see the outbound request but not the reply. Will the cap show me anything more?Do
tcpdump host $serverinstead. Otherwise you will only see the request (the response goes to a different port).
