Hi
Jonathan
,
I'm guessing these IoT devices are on the same LAN as other devices that do not require this specific DNS entry?
I would say using DHCP options would solve this problem for you but the 2927, and most - or all other models, do not support Host-specific level options. To get that you'd need to host an external DHCP server (that can cater to those granular settings) or create a new subnet VLAN with the specific DNS entry (or entries) you desire within that subnet's DHCP settings on the 2927 and then inter-link that subnets with any others that require access.
(If I am understanding your dilemma correctly?)
Thanks for replying.
Yeah so the IoT devices (robot vacuums) are on their own VLAN which is shared with some other devices - they pull IPs via DHCP from a scope for that VLAN - the DNS for that scope points to my piholes that do the DNS filtering 10.7.0.xxx
Because these IoT devices 'phone back' to China etc I was looking at running them through my NordVPN connection so they go through a VPN. The issue I have is that if I point the IoT device to my pihole custom DNS, it creates a DNS leak. So I was thinking about trying to 'point' those devices to Nords VPN DNS but I can't do that manually as there's no way to change the DNS IP on the devices itself, hence asking about DNAT to redirect the DNS queries.
So yeah, maybe it's best if I use LAN7 which is free and change the DNS entry in the scope to NordVPNs DNS and then connect the IoT devices to that VLAN associated with LAN7 perhaps.
