2. Modify the match criteria of your dynamic address groups to follow the format required for a security-centric deployment.
   1. Select ObjectsAddress Groups.
   2. Verify that you are configuring the dynamic address groups in a device group associated with an NSX-T service definition.
   3. Click on the name of a previously created NSX-T dynamic address group.
   4. Edit the match criteria.
      For the dynamic address group to become a security group in NSX-T Manager, the match criteria string must be enclosed in single quotes with the prefix _nsxt_ followed by the exact name of the Address Group. For example, ‘_nsxt_PAN_APP_NSX’.
   5. Repeat this process for each security group you require.

3. Set the security rules to be as NSX-T steering rules to intrazone.

   4. Set the Rule Type to intrazone (Devices with PAN-OS 6.1 or later).
   5. In the Source tab, set the source zone to the zone from the template stack associated with the service definition. Then select a dynamic address group you created previously as the Source Address. Do not add any static address groups, IP ranges, or netmasks as a Source Address.
   6. In the Destination tab, Panorama does not allow you to set a destination zone because you set the rule type to intrazone. Then select a dynamic address group you created previously as the Destination Address. Do not add any static address groups, IP ranges, or netmasks as a Destination Address.
