DNS issues OPNSense + Proxmox + Hetzner

[oulet]

Hi, excuse me as a newbie if I come with a question already addressed. Also, excuse my English. Now to the point. I have a dedicated server from Hetzner (2public IPv4 + IPv6 /56 subnet) - Proxmox installed on the server (first IPv4) and OPNSense on the VM (second IPv4).

On the other VM I have a webserver (openlitespeed).

I'm interested in how to spoof DNS servers (either my own or e.g. Cloudflare) via OPNSense to visitors to hosted sites on the openlitespeed VM so that when they view domains on their machine they don't get DNS from their ISP, without them having to change DNS on their routers or NICs themselves.

Is it possible to do it this way, for example? https://forum.opnsense.org/index.php?topic=10670.0

Or via the os-tor plugin?

Thank you very much for the initial introduction to the solution via OPNSense
