Random Discovery service added to devices

Hello, I keep getting these although I added inbound rules to allow traffic from a lot of ports but I need that for the STUN server. I also added cwmp.auth() in config but these random devices still log in to the server.

also has this problem
this is seems to be network scanners that search for vulnerable cpes over internet at tcp port 7547

Enable connectionRequestAuth and only allow authenticated CPEs to connect.

Admin → Config → New config
Key: connectionRequestAuth
Value: AUTH(username, password) OR AUTH("someUsername", "somePassword")

I did this but i still run into the same issue
