Understanding GTP Message Filtering
When the device receives a GPRS tunneling protocol (GTP) packet, it checks the packet against policies configured on the device. If the packet matches a policy, the device inspects the packet according to the GTP configuration applied to the policy. If the packet fails to meet any of the GTP configuration parameters, the device will pass or drop the packets based on the configuration of the GTP inspection object.
