On a whim - geez I regret it now - I installed the wireguard-kmod package to test it out. After rebooting, all DNS resolution in my network failed.

I use a separate box running Pi-hole/unbound to provide DNS. I can ping the box from OPNsense, I can SSH to it. The IPs are being handed out as DNS. But resolution fails.

So I removed wireguard-kmod, rebooted, and even did a config restore from a backup. Still not fixed.

I have double-checked firewall rules and all looks OK (they haven't changed). I am at total loss as to what the issue is. Any clues anyone ... please?

Thanks, that was one of the first things I checked as I knew about WG's behaviour. But I don't have DNS configured on any of my WG configs on OPNsense anyway.

But - after a couple of hours, the issue seemed to resolve itself. Weird.
