Trouble Passing Real Client IPs from Dnsmasq to AdGuard Home → NextDNS

Routers
1

Hi everyone,
I'm running a layered DNS setup at home for better control and visibility:
Device: GL-MT6000 Flint2 - OpenWrt 21.02-SNAPSHOT
Kernel: 5.4.238

LAN client → Dnsmasq (handles DHCP & DNS) → AdGuard Home (ad-blocking) → NextDNS (DoH resolver)

Dnsmasq is handling DHCP and DNS.
AdGuard Home is running on my GL.iNet Flint 2 router.
NextDNS is configured in AdGuard Home as the upstream resolver via DoH.
On NextDNS, I do see the real client IPs (great!).
But in AdGuard Home, all clients appear as 127.0.0.1 or the router IP, not the actual LAN device IPs.

I already tried:

Setting add-mac, add-subnet=32,128 in dnsmasq.
Enabling EDNS Client Subnet (ECS) support in AdGuard Home.
Testing with and without strict-order , bogus-priv, no-resolv options.
Verified DHCP leases are assigning correctly and contain MAC info.

Still, AdGuard Home doesn’t log the real LAN client IPs, which makes per-device filtering and stats useless.

What I want:
See real LAN client IPs inside AdGuard Home, not just on NextDNS.

My Questions:

  1. Is there a known method or config combination that allows dnsmasq to pass real client IPs to AdGuard Home running on the router?
  2. Does AdGuard Home need to run on a separate device to capture LAN IPs properly?
  3. Would changing the chain (e.g, clients → AdGuard → dnsmasq → NextDNS) help resolve the IP logging issue?
    Any advice or insight would be appreciated. Happy to share more config details if helpful.

Thanks in advance!
Arnold

Hello,

  1. Is the MT6000 installed firmware version v4.7.7?

  2. Is VPN client disabled?

  3. Is the "AdGuard Home Handle Client Requests" enabled?

Hey Bruce, tks for your time.

Version ok V7
No VPN, I'm using Tailscale instead.
Clinet Request. I don't know what is this option. However, only to make it clear, this is my setup: clients → AdGuard → dnsmasq → NextDNS Therefore, dnsmasq is handle clients and Adguard is the ad blocker.

I fill like I'm missing something.
File etc/dnsmasq I've included:
no-resolv
bogus-priv
strict-order
server=127.0.0.1#3053

And have tried many diffent way testin flaging and unflagging AdGuard options. Nothing make it works.

Maybe my setup is not appropriate one.

Tks again.

Hey, tks for you question. Nope... I didn't enable because I'm using dnsmasq as my DNS. The Idea is to use Aduard only as ad blocker.

Cheers.

And the only reason that I'm using AdGuard is because Flint 2 has it already integrated. Otherwise, I would prefer Pi-Hole. But, for it will be required an extra container or vm, and I don't wanna at least for now extra stuff to manager.
cheers

The reason is the dnsmasq already handle all DNS requests, ADG can only display localhost. I think this is not an issue in router firmware.

If you require the ADG statistics list to display client IP, may enable the "AdGuard Home Handle Client Requests".
