I am a happy user of the BE65Pro. I have added pihole to my network and that works fine for the normal network devices. However, I also have IoT devices which are isolated, and a guest network, and I would also like to have them going through pihole for DNS.

 

Can this be configured? Or will there be a future option to allow for this?

 

And I also would like to know what is happening in the current config, as my internal pihole is handed out as the DNS by the DHCP server functionality. What DNS are they using, because it still seems to work.

 

Regards,

Marcel

Found out that it does not work correctly. The guests network totally fails on DNS, because it cannot reach the pihole. But a lot of devices like android have something called "Private DNS" which totally bypasses your DNS structure. Also found that my work machine also has Cisco umbrella which also captures all DNS traffic and routes it to whatever your company wants to use.

 

And a lot of IoT devices have 8.8.8.8/8.8.4.4 hardcoded in them so they don't show up either. And for that reason they keep working if they are on an isolated IoT segment which can't reach pihole if the device is marked as "isolated". Disabling isolation makes the pihole visible to them... but if they are not using it because of hardcoded DNS servers that is pretty useless.

 

So that leaves me with only the Samsung TVs, Sonos, Nintendo being filtered/cached. This trend makes the whole DNS filtering less useful. Still I think it would be useful feature to be able to allow access to a few addresses from the IoT and/or Guest network to allow for such features.

 

Any other solutions/ideas? Would be great to hear them!

Hi, 
If your Pi-Hole is connected to the main network, the device connected to the guest network, and the isolated IoT device can't access the Pi-Hole. If these devices have other DNS servers configured, they may go to the internet bypass Pi-Hole.

 

Do you want the device connected to the guest network and isolated IoT device to be able to access specific devices on the main network?

 

Best Regards
