💫 The easy way to synchronize the DNS configuration of two Pi-hole 5.x instances.
Multiple PiHole nodes is the best way forward in my opinion since it will ensure that ad/tracking blocking will work no matter what. Personally, I run 3 -- two that server my LAN and a third that's my test device to test new versions of PiHole, new adlists, or just to help troubleshoot what domain(s) I may need to whitelist to get a site to work properly. If you decide to run two nodes, look into the gravity-sync project which would keep the nodes in sync so you don't need to manually manage both.
What's the best way to force all traffic through the pihole for any devices that may have hardcoded DNS on an ASUS router with Merlin?
