    I am using DNS-Over-TLS with Cloudflare(configured on WAN page). I also have DNSFilters enabled and configured to allow my kids devices to use OpenDNS Home bypassing the DOT Cloudflare but allowing me control over adult content/whatecver.

    I also have a PiHole server setup and have used DNSFilters to direct a few "un-trusted/semi-trusted " network devices(like cheep china security IPCams) that I have directed to the PiHole. The issue is that all the requests from the devices assigned the to PiHole DNS all show from 192.168.1.1(router IP).

    Is there a way to have the router assign the IP of my PiHole or OpenDNS Home to the devices and not route it through the router so I can see which device is making the requests to the PiHole or OpenDNS Home.

    Every device on the network shows its DNS server as 192.168.1.1

    As I am typing all this I tried the LAN -> DHCP Server page.
    It appears I can assign the DNS Server there and it will pass the DNS SErver setting directly to the Device, bypassing the router.

    This is a usable solution for the time being.
    So, can the DNS Server field on the DNS Server page contain more then 1 Server/IP?
    I.E.: 1.1.1.1, 1.0.0.1

    And is there a better/more elegant way to do this?

    Next I would like to specify the DNS Servers for Guest clients and not have it assigned the router IP.
    I want to pass the DNS Server IPs to the guest client like what happens on the DNS Server page example above.
    Specifically I would like the DNS Server IP for my guest clients to be the PiHole DNS IP and not 192.168.1.1.

    Network Setup:
    192.168.0.0/20
    with DHCP from 192.168.14.200-254
    I have a VPN Server that has a subnet of 192.168.15.0

    I have:
    The wired devices
    3 SSIDs:
    House-Main
    House-Security
    House-Guest

    Every non-guest device on my network is assigned a static IP.
    Every other device goes to the DHCP Pool

    Any guest wanting access to the network is given the password to Home-Guest SSID

    So the solution, as I see it, would be to pass the PiHole IP(or whatever IP I want) to any client connected to the DHCP Pool but I am OK with all the Static Clients using the router IP

    These are my current Settings:
    WAN - Internet Connection

    LAN - DHCP Server

    I don't have any AMTM DNS Scripts/Installed

    Now that I have my network setup out there I cant wait to hear all the head shakes, face palms, and eye rolls. I can take it!!

    Thanks for making it this far down the post,

    Don
