21.1 Legacy Series / [SOLVED] WireGuard-kmod installation breaks DNS?
« on: June 18, 2021, 04:06:17 pm »
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?
