[fixed] Pi-Hole newbie with DNS issues

@deHakkelaar
Been considering this in the past, thank you, but I don't feel inclined to do it just now. It looks like I should do it, one of these days! I fondly remember DD-WRT being a major upgrade for my trusty old Linksys WRT54G.

@Bucking_Horn
Switching DHCP over to Pi-Hole seems to have resolved the initial problem, blocking works. The only caveat is when running pihole -d, Networking reports errors:

*** [ DIAGNOSING ]: Networking
[✓] IPv4 address(es) bound to the eth0 interface:
192.168.1.200/24 does not match the IP found in /etc/pihole/setupVars.conf (Use IPv6 ULA addresses for Pi-hole)

[✓] IPv6 address(es) bound to the eth0 interface:
fe80::9edd:b635:2879:d87e does not match the IP found in /etc/pihole/setupVars.conf (Use IPv6 ULA addresses for Pi-hole)

^ Please note that you may have more than one IP address listed.
As long as one of them is green, and it matches what is in /etc/pihole/setupVars.conf, there is no need for concern.

The link to the FAQ is for an issue that sometimes occurs when the IPv6 address changes, which is why we check for it.

[i] Default IPv4 gateway: 192.168.1.1
192.168.1.1

I'm worried about the error messages showing up. Any pointers on how to fix it?
Still no access to the admin panel via http://pi-hole/admin … no deal breaker, but maybe related to other settings still not being ideal.
192.168.1.1 = Asus router, static IP, DHCP turned off
192.168.1.200 = Pi-Hole, DHCP ranges from 192.168.1.201 to .251
