I initially had some setup issues with Adguard related to my Keepalived setup - Adguard was bound to by default, yet any requests I sent to it via the keepalived virtual IP received responses from the real IP of the VM, not the Keepalived virtual IP. This pretty much broke DNS for any system with a firewall on it as the response was no longer classed as a related or established connection. Binding Adguard to the virtual IP instead cured this, but it also means I can't manually query it directly for testing purposes (e.g. if it's not the keepalived master or I'm unsure).


Apart from that niggle related to my setup, it's been solid, running for a week now and clocked half a million DNS queries. Haven't really noticed much different positive or negative compared to Pi-hole. The web interface is nice and clean.

I took a quick look at Adguard, I'm not sure why people are saying its better.. it's more or less identical to pi-hole and doesn't offer any benefit over it


It only uses Adguard's own list by default, it doesn't block ads in Youtube on Android and iOS devices. It's almost impossible to block these ads using DNS based blockers because the ad content is delivered from the same server as the actual video content, not a seperate ad domain


From memory I couldn't see any easy way to click on a client and see its requests, but I can't remember as I deleted the VM


I also use pihole with keepalived, good to see others doing that too

Had my first issue with Adguard, but it was a misconfiguration on my part: I hadn't configured an upstream for local reverse DNS. 


This caused some MySQL authentication failures between VMs as creds were limited to particular hosts by hostname, but they started getting checked by IP due to broken rDNS. 


In addition to the config lines for my upstream DNS servers e.g. cloudflare or quad9, I now have:




First says that DNS lookups for subdomains of my.home.domain (not my actual domain, altered for privacy) goes to my router (which is the DHCP server and has dnsmasq).


2nd rule is the new rDNS rule i.e. send 10.10.x.x rDNS queries to my router. 


Pihole does this via a more user friendly form field in the advanced DNS settings area.
