block unknown client

[gab12]

Hello,
I often see that unknown connections (CN, RU etc.) are querying and use my Adguard Home.
I have to check regularly and block them.
All my devices have a specific client id.
Those who do not are therefore necessarily intruders.

I don't know how they find my adguard, but I would like a feature to block all requests from an unknown client. but impossible. How will you do it if possible? thank you in advance

Hi you can use DNS settings -> Access settings -> Allowed clients to allow only your clients.

Thank you for your answer.
The problem is that it is not a checkbox .. you must indicate the client's IP and not his ID client.
And on my 4G phone, my ip is not fixed. :( Si I can't whitelisted him.

note: still today i still had 5 news unknown clients. (21 requests :( )

Please note, that access settings currently only work for plain non-encrypted DNS.

You can even block ALL clients like this 0.0.0.0/0, but your DOH resolver will continue to work.
