About firewall settings

Firewall settings are required to communicate with NetVault Clients that reside outside the firewall. You can use these settings to specify the TCP/IP ports for establishing data transfer channels, message channels, and broadcast channels through the firewall.

You can configure the firewall settings when deploying or adding a client, or update these settings from the Change Settings page. You can also use the NetVault WebUI or Txtconfig utilities to configure the firewall settings for new or existing clients.

NetVault does not support firewalls using NAT (Network Address Translation)/IP Masquerading.

The following table provides a brief description of the firewall settings.

Listen ports for devices

Ports to listen on for device requests.

Configure this option on the NetVault machines that have a locally attached device (for example, NetVault Server or NetVault Clients with SmartClient licenses).

Requirement: Two ports per drive.

Connect ports for devices

Ports that plug-ins use to connect to remote storage devices.

Configure this option on clients that connect to remote devices.

Requirement: Two ports per drive.

Listen ports for NetVault message channels

Ports for receiving messages during data transfers.

Configure this option on both the NetVault Server and the Client. NetVault requires a two-way connection between the Server and the Client for message channels.

Requirement: Three ports per client.

To run two or more plug-ins simultaneously on a client, configure two ports per plug-in and an extra port per client. For example, to run two plug-ins simultaneously, configure (2 * 2) + 1 = 5 ports for a client.

Connect ports for NetVault message channels

Ports for sending messages during data transfers.

Configure this option on both the NetVault Server and the Client. NetVault requires a two-way connection between the Server and the Client for message channels.

Requirement: Three ports per client.

To run two or more plug-ins simultaneously on a client, configure two ports per plug-in and an extra port per client. For example, to run two plug-ins simultaneously, configure (2 * 2) + 1 = 5 ports for a client.

Connect ports for NDMP control channels

Ports for sending NDMP messages (NDMP control channels).

Configure this option on the NetVault Server (on which the plug-in is installed) when a firewall separates an NDMP filer and the NetVault Server.

By default, NetVault uses port number 10000. You can change it, if necessary.

Listen ports for NDMP data channels

Ports to listen on for NetVault devices operating as NDMP movers.

Configure this option on the NetVault Server or Client to which the device is attached. These ports are used for data transfers between the NDMP filer and storage device when a firewall separates the two networks.

Connect ports for inter-machine setup

Ports for establishing initial contact (broadcast channels) while adding a NetVault Client, and later to ascertain its availability.

Requirement: Two ports per client.

You can use the following formats to specify the ports or port ranges for data channels, message channels, and broadcast channels:

Firewall configuration example

This example illustrates the network port requirements for a NetVault system with the following configuration:

Server (with locally attached storage device)

Connect ports for inter‑machine connection setup

Minimum two ports per client

24

50300-50323

Connect ports for NetVault message channels

Minimum three ports per client

40

50200-50239

Listen ports for devices

Minimum two ports per drive

12

50100-50111

Client

Connect ports for inter‑machine connection setup

Minimum two ports per client

(These ports can be the same as the ports specified on the server side.)

24

50300-50323

Listen ports for NetVault message channels

Minimum three ports per client

40

50500-50539

Connect ports for devices

Minimum two ports per drive

Locating a client

The clients that reside in a different subnet are not included in the list of available clients. You can use the Find Machine option to locate and add such clients.
