Private DNS doesn't apply to devices connected through hotspot? (self.askandroid)

I've set a specific provider under the Private DNS setting and it works for the direct connection between the phone and the network, but it won't work on the devices that are connected to the hotspot of my phone, they instead fall back onto the default DNS of my ISP.
Is there a way to force that DNS on all the devices connected?

Seems like a simple fix, just manually set the DNS servers on devices that connect to your hotspot

I wish it were that simple, but that's sadly not really a solution in every case, I'd have to set up that DNS for every device that connects to it first, even those that aren't mine

If a device isn't yours, wouldn't it be the device owner's responsibility to maintain their own privacy?

This is about network policy, my device working as the DHCP server has to impart the devices that connect to it with their IP, gateway and DNS, it isn't necessarily about individual user privacy. In my case it is more for my own privacy/security, I don't want others to send DNS requests to my ISP because I trust the filters on my DNS of choice more.
Of course, if they really wanted, they could still set their own DNS on their device, but this is meant for those that don't even think about it

Now I get it

I know that if you have a VPN running, there's a setting "Allow clients to use VPNs". You might be able to install WireGuard and set up a connection with no peers, but still set what DNS server you want to use, then allow clients to use the VPN, which might give the clients the VPN's DNS settings

So I should try with this Wireguard app?

This is the one I use

Ok, thank you! I'll try to figure out how to use it
