Hi,
I'm setting up an OPNsense box and for the most part, it's going very well. I'm trying to setup Unbound Query Forwarding for just two interfaces on the box and it's not working. As soon as I enable Unbound, DNS resolution stops working (for the clients that are meant to use it). If I set the exact same DNS server in DHCP, everything just works.
Also, with Unbound enabled, the firewall is able to resolve domains from those interfaces but the clients on those interfaces cannot. I've checked my firewall rules and it's not that - an allow any to any rules gets the same result. It's also not a DNSSEC issue - same result with or without DNSSEC.
Any ideas where I should look to find the issue?
This is resolved. Needed to fiddle with my gateway settings.
