DMZ 🚀
The DMZ section is the basic interface for configuring the DMZ Driver, gateways, servers, and links within Data Mover Smart.
The DMZ section requires a specific license.
At least a Cluster must exist. If not, the Create Cluster option will appear on the DMZ page.
DMZ Driver configuration
To set up the DMZ Driver, click the DMZ Driver button located at the top-left corner and in the DMZ Driver window fill in these fields:
Bind address: IP address through which Data Mover Smart is accessible from the external.
Local address: (Default value: 0.0.0.0). Local IP address the DMZ Driver uses to bind incoming and outgoing connections.
Reserved ports range: TCP-IP port ranges to be used to open tunnels between DMZ Driver and DMZ Gateway. For each incoming/outgoing connection, one port should be reserved (2 ports are needed for FTP protocol). Ensure these ports are open on both the DMZ and Data Mover Smart.
Socket timeout: (Default value: 30 seconds). Timeout duration (in seconds) for read/write/connect operations on the DMZ Driver–DMZ Gateway tunnel. Use -1 for an infinite timeout.
Idle timeout: (Default value: 90 seconds). Duration (in seconds) to keep the connection alive between the DMZ Driver and DMZ Gateway.
Reconnection interval: (Default value: 30 seconds). Time (in seconds) before the DMZ Driver attempts to reconnect to the DMZ Gateway after a disconnection,
Reconnection attempts: (Default value: -1). Number of reconnection attempts before considering the DMZ Gateway unreachable. Use -1 for unlimited attempts.
Click the Save button to apply and confirm the DMZ Driver settings.
Gateway configuration
Once the DMZ Driver is set up, you can create Gateways that will appear in the corresponding drop-down list.
Choose the appropriate cluster from the drop-down menu. To configure a Gateway, click the + button below the Gateway panel and fill in the fields:
Name: enter a unique name for the Gateway.
Description: optionally, provide a brief description to identify the Gateway’s purpose or role.
Internal address: specify the internal IP address used by the Gateway.
Internal port: enter the port number for internal communication.
External address: provide the external IP address through which the Gateway is accessible.
Once all fields are completed, the 
Save button will become active. Click it to confirm and save the Gateway settings.
Servers and Links
On the right of the screen, all Servers and Links configured on the DMZ are listed.
Servers
The Servers section displays the servers where the DMZ is active.
As soon as the DMZ toggle is enabled when creating or editing a Server, the relevant entry will appear in this list.
To add a new server from the DMZ page, follow these steps:
Click the + button located in the lower-right corner of the screen.
A panel will appear. Click Choose Server to open the selection window. Pick a server from the list and click Confirm.
Each server can be selected only once.
In the Mode list, select Port Forwarding.
Enter the port number used to contact this server externally via the Data Mover Smart gateway.
Once all fields are completed, the Save button will become active. Click it to confirm and save the settings.
Links
The Links section displays all links (i.e., client connections and remote nodes) where the DMZ is active.
As soon as the DMZ toggle is enabled when creating or editing a Link, the relevant entry will appear in this list.
To add a new link from the DMZ page, follow these steps:
Click the + button located in the lower-right corner of the screen.
A panel will appear. Click Choose Link to open the selection window and select a link from the list. If you need a PR4 Node, click the Remote Nodes option to access the relevant list. After choosing the link, click Confirm to proceed.
Each link can be selected only once.
Choose a specific cluster from the list. If no cluster is selected, Data Mover Smart will apply the link to all clusters by default.
Once all fields are completed, the Save button will become active. Click it to confirm and save the settings.
