Help! DNS A Records only ones getting filtered. (lemmy.world)

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.

Seems weird to me, the router would need to do deep packet inspection of DNS and selectively block specific ones. It feels more like you've set up your DNS to do forwarding instead of resolution. Can you post a network diagram and the DNS config?
