However, this dnsmasq instance operates with a configuration specifically generated for WAN connectivity, limiting the ability to persistently integrate ctrld's configuration. Consequently, client DNS requests will not be routed to the ctrld listener. + +To resolve this, users must either modify the existing firewall rules or create new rules with higher priority to direct DNS traffic to the ctrld listener. Modifying UDM configurations directly, outside of the web interface, carries significant risk and is not officially supported. Such modifications may lead to system instability or failure, and should be undertaken with extreme caution. \ No newline at end of file
