Hi
Why the clients behind router connecting direct to *dns.adguard.com:53? This DNS server I configured in router as upstream.
Should the not connect to router for DNS? Then router query upstream DNS and cache it?
Or I got something wrong?
Remove DNS-related DHCP options if any:
uci -q delete dhcp.lan.dhcp_option
uci -q delete dhcp.lan.dns
uci commit dhcp
/etc/init.d/dnsmasq restart
/etc/init.d/odhcpd restart
Reconnect your clients to apply changes.
Set up DNS hijacking if the issue persists:

dhcp.lan.dhcp_option and dhcp.lan.dns were already empty

Make sure your clients are configured to use only DNS provided by DHCP.
If you see the wrong DNS queries, you should also be able to identify their source.
