Techniques for enforcing packet detection rules within communication systems are provided. A network entity may configure a user plane function to detect whether a domain name system request sent by a user equipment satisfies one or more packet detection rules. The network entity may receive, from a user plane function, a report that a domain name system request sent by the user equipment has been detected as non-compliant with instructions sent to the user equipment. The network entity may cause one or more corrective actions relating to traffic offloading.
