# DMZ Clusters

In the **Setup** → **DMZ Clusters** section, you can add, modify or delete a cluster of DMZ gateways.

DMZ Clusters can be filtered in the **Filters** panel on the right of the page. Entries can be filtered by Name or ID KEY.

Learn how to use the **toolbar** at the top of the page [here](/data-mover-1.21/getting-started/navigate-through-primeur-data-mover.md#the-toolbar).

To edit or delete the DMZ cluster, select the ![](https://files.readme.io/2ff4228-three_dots_icon.png) 3-dot icon and choose the **Edit** or **Delete** option.

To create a new DMZ Cluster, click on **Setup** → **DMZ Clusters** → **New**.

3 tabs will appear:

1. **Cluster configuration**: this tab allows you to define and manage the settings of the DMZ cluster.
   * Name (\*): mandatory identifier for the DMZ cluster.
   * Description (\*): mandatory description of the DMZ cluster.
   * ID KEY: unique key used for internal identification.
   * Enabled / Disabled toggle: enables communication between the DMZ cluster and server connections.\
     Note: This toggle does not apply to client connections.&#x20;
2. **Gateway**: this tab allows you to select a DMZ Gateway (previously configured in the [DMZ Gateways](/data-mover-1.21/infrastructure/dmz-gateways.md) section) and apply it to the DMZ cluster.
3. 🚀 **Client connection**: this tab displays the client connections where the DMZ cluster is used.&#x20;
   * Link: click to open the Client Connection associated with the DMZ cluster.&#x20;
   * Type: protocol used in the Client connection.
   * Name: name of the Client connection.&#x20;
   * Description: description of the Client connection
   * Actor: actor of the Client connection.&#x20;

You can edit and delete the DMZ cluster by clicking the 3-dot icon and selecting the relevant option.&#x20;

When you delete a DMZ cluster, a warning message will appear if the cluster is currently used in one or more Client Connections. The message will inform you that the cluster will be removed from all associated Client Connections. If you are deleting the **last cluster** linked to a Client Connection, the message will also indicate that **Data Mover will automatically detect and assign an available DMZ cluster** to ensure continuity.

Since the DMZ Gateway is a secure ‘door’ to access Data Mover from the Actor connections, the **enable** toggle turns on/off this door. Only registered users (bound to a partner) can access an enabled door.
