Comment on Devices getting router IP as DNS

Like the other poster said, this will be configured on your routers settings. You can configure more than one DNS address, the 2nd (etc.) being backups if the first one stops working.

The router is running DHCP and is set to hand out the Pi-hole IP as DNS. Interestingly, there’s only one field for this so maybe the router is choosing itself as DNS2? If I go into WAN settings, there are fields for DNS1 & 2 but if I was under the impression that these should be set for upstream DNS.

I’m running the Merlin fork of the Asus firmware, so maybe that adds this option, but in my DHCP settings there’s a switch called:

Sidenote: The Merlin version of the firmware is great! It lets you run the Diversion adblocker, which functions in the same way as Pihole. However, the RT-AX55U isn’t supported. The AX58U is though, maybe it might be worth upgrading? It’s a lot simpler than running a Pihole separately.

OK, this seems to be the issue. I have this section but only one field for DNS.

If you can’t figure it out, you can always use your PiHole as a DHCP server.
Try set those to your PiHole IP. Then, even if a DNS request goes to your router, it should send the request to PiHole rather than the ISP’s DNS servers.
By the way, I’d recommend running two PiHole instances so that the internet doesn’t break if you have to take one of them down. There’s a system for AdGuard Home that lets you keep the config for multiple instances in sync - maybe there’s something like that for PiHole too.

Last time I tried that was… problematic. I suppose I could try again…
I’m kinda just getting started. The goal is to have a media server in addition to my current raspberry pi server that will act as a second dns. If I can’t find a way to keep them synced, I’ll give adguard a try
