+        trusted_ip_list is a list of IP addresses on each iscsi gateway that
+        will be used for management operations like target creation, lun
+        exporting, etc. The IP can be the same that will be used for iSCSI
+        data, like READ/WRITE commands to/from the RBD image, but using
+        separate IPs is recommended.

       .. important::
         The ``iscsi-gateway.cfg`` file must be identical on all iSCSI gateway nodes.
