# GTP Inspection Object List

By selecting the GTP service in a policy, you enable the NetScreen device to permit, deny or tunnel GTP traffic. However, this does not enable the device to inspect GTP traffic. In order for the NetScreen device to inspect GTP traffic, you must apply a GTP configuration, also referred to as a GTP Inspection Object, to a policy. Before you can apply a GTP configuration to a policy, you first have to create a GTP Inspection Object. You can apply only one GTP Inspection Object per policy, but you can apply a GTP Inspection Object to multiple policies. Using policies, you can permit or deny the establishment of GTP tunnels from certain peers such as an SGSN.

## Viewing the GTP Inspection Object List

This table lists every GTP Inspection Object configured on the NetScreen device and contains the following information on each one:

GTP Inspection Name: Indicates the name of the object.

Configure: Click Edit to modify the GTP Inspection Object or click Remove to delete it.

Note: If you apply a GTP Inspection Object to a policy and then delete the object, this action also removes the Inspection Object from the policy.

### To Configure a GTP Inspection Object

To configure a GTP Inspection Object, click New. For more information, see GTP Inspection Object Basic Configuration.
