Expected Behaviour:
I have set up Pi-Hole on a PineA64+ with Armbian Bionic. The Web portal appears to indicate that everything is set up fine. I have configured my ASUS RT-AC58U so that the DNS settings under WAN point to my Pi-Hole box. http://192.168.1.200/admin/network.php reports that my router and 127.0.0.1 are using Pi-Hole. I would expect all clients connecting via the router (i.e. using its DHCP) should be using Pi-Hole. Pi-hole was set up to use OpenDNS which is working for all the clients.
Actual Behaviour:
The Pi-Hole web interfaces says that my clients are not using Pi-hole and adverts are not being blocked. I have tried disconnecting and reconnected to the network so that DNS settings are properly updated.
I have also noticed that not all my clients are appearing in the network overview of Pi-hole.
