modem under pihole it's not protected

hi all, when i check the lists of the devices under pihole in my lan i got the modem's ip that is not under the 'protection' of the program. it appears like this:

ip modem

i wanted to know if there is a way to got the screen green since i have another router in the house which takes the signal from this one, so i would like to put this modem under pithole in order to get the protection also in the other router.

Expected Behaviour:

the screen should be green

Actual Behaviour:

the screen is red

Debug Token:

This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations.  This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected.  Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

Can you set the DNS settings on the modem's web interface. Is the modem in bridge mode?

As you can see in the network overview, the modem hasn't send any query to pihole yet (that is why it is red). This might be due to two reasons: it is not using pihole as DNS server or (also likely) it has not requested a sigle DNS resolution yet at all. It might be only doing so when refreshing NTP servers from time to time or looking for web firmware upgrades.

since it's not possible to set the dns server on the modem i configured pihole as dhcp server

To elaborate a bit on yubiuser's answer:

It is common for routers or modems to use the DNS server as assigned to them by your ISP. Thus, it would be normal for those class of devices to never appear as a client in Pi-hole (as long as they are indeed providing your connection to the Internet).

ok, thank you for the explanation, i think i got the point.
but anyway is there a way to let the modem 'ask' protection from pihole? in this way i get the protection also on the router linked to the principal modem.
another option could be to assign to pihole the ethernet door from which starts the cable that links the modem to the router, but i dont' know if it's possible.

or do you think it could be better to install a pihole on the secoundary router?

If you can't set the DNS server on the modem there is no way (I can think of) how to force the modem to use Pihole.
(And I think you have a misinterpretation of "protect" - pihole isn't really protecting the device from anything but it is protecting you from devices making queries to servers you might not want them to contact.)

I think I need a schema drawing from your network topology....

In case you are worried about your router/modem exposing sensitive data by (publically) contacting third parties (e.g. its manufacturers), you should probably consider to buy another router altogether (and yes, there are routers out there that perform data acquisition on behalf of their manufacturers, with or without asking for your consent explicitly).

If your router supports it, you could consider to use custom OSS firmware that would allow you to exercise that kind of control (and also is much less likely to monetise your data in the first place).

Who is saying that the modem needs DNS at all? If is just a plain simple cable modem, it will only do PPPoE and does not need to be able to resolve any domains at all.
