 For enhanced security, prevent wireless guests from accessing other DNS services by creating a firewall rule on the router (if supported). This rule should allow access only to Cloudflare's DNS servers and block all other DNS destinations on UDP/TCP port 53\. Additionally, some advanced wireless routers support content filtering. If available, enable options to block DNS over TLS (DoT) or DNS over HTTPS (DoH) to ensure endpoints cannot bypass your configured DNS security settings in Cloudflare.
