PiVPN with Wireguard and PiHole not working correctly

ok I was asking because Docker block routing functionality by default https://docs.docker.com/network/iptables/#docker-on-a-router
But if it is not installed, it should not have an impact

trendy
It’s about Wireguard server installed on the DietPi device where it is not possible to reach systems behind DietPi/Wireguard server. Something wrong on routing from wg0 interface into local network.
