Gateway (member) 25 The **Gateway mode** can be used if a local member state gateway server is in place. Then the job scripts can be submitted to the ECMWF Linux member state server via the ECMWF web access tool ``ecaccess``. The installation script of ``flex_extract`` must be executed at the local gateway server such that the software will be installed in the ``$HOME`` directory at the ECMWF server and some extra setup is done in the local ``flex_extract`` directory at the local gateway server. For more information about establishing a gateway server please see`ECMWF's instructions on gateway server`_. For the **Gateway mode** the necessary environment has to be established which is described in :ref:`ref-prep-gateway`.25 The **Gateway mode** can be used if a local member-state gateway server is in place.
