Guest network not getting DNS

[jfb]

@rvk

you can point the public dns to one of the publicly available pi-holes.

This is strongly frowned upon - maintaining an open resolver.

Edit: BTW, what happens if you set 192.168.1.40 and 172.16.42.40 as dns in the private dhcp? If one is unreachable the other should be used. That way you can use the internal dhcp of the AE. Both would have one valid dns-ip (and one invalid).

I already tried that but guest network is not using the DNS settings of private network. I think the best would be to buy other equipment.

Yes, that seems the best way.

Make sure it meets all your requirements. I have an ASUS RT-AC68U of which I needed to replace the firmware with Asuswrt-Merlin because the original firmware always adds itself as second DNS server. And standard Merlin also doesn't have DNS setting for guest-network (but there is an extension for that). So you probably want a router which already has all features build in. (Not sure which one would qualify)
