Setting Up LANCache + Unbound

[ticker]

I currently have OPNsense setup with Unbound, and all devices on the network use it. I want all the devices to connect directly to the firewall IP for DNS. I have a few VLANs, and port 53 is forwarded locally for all so they can reach DNS (correct me if there is a more secure way of doing that).

Now I want to setup LANCache, likely in Promox.
I do not want to have to have the computers connect to LANcache as their DNS. I want them to connect to opnsense as they currently are. But have LANcache work in the background alongside Unbound if that makes sense.



Basically I want all devices to point to 192.168.1.1 (firewall) for DNS, but if they are downloading something LANcache supports, LANcache feeds them that data.
How would I set this up ideally?

Why not use squid that's built into opnsense, seems easier and more logical, it has caching options and you'll have it all in one box. Looks like lan cache needs to be a dns server in the network, you can always point your dns on pfsense to forward dns queries to it if you want to.
