Hello,
I'm on the way to switch to OPNsense so I'm trying it on my lab (Proxmox cluster).
WAN vtnet0 is on my public lan side 10.10.1.0/24
LAN vtnet1 has it's own vlan to play with 192.168.1.0/24
Fresh default install of OPNsense 24.1.1, just did the System > Firmware updates "There are no updates available".
On the LAN side clients can reach the Internet : ping 1.1.1.1 is Ok
But they can't resolve DNS hosts : nslookup google.com 192.168.1.1 gives SERVFAIL error
On the OPNsense host I can resolve DNS :
- ping google.com > Ok
- host google.com 10.10.1.1 (upstream) > Ok
- host google.com 127.0.0.1 > SERVFAIL
What I can conclude is that the unbound server is answering but not resolving hosts right ?
Do you have any idea what I could me missing ?
Thanks for reading.

Ho ok, it was hidden if on the "Request Forwarding" page : I had to activate "Use System Nameservers" and there I go!
Thank you 8)
