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

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

Table 17. Firewall settings
Option	Description
Listen ports for devices	Ports to listen on for device requests. Configure this option on the NetVault Backup machines that have a locally attached device (for example, NetVault Backup Server or NetVault Backup 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 Backup message channels	Ports for receiving messages during data transfers. Configure this option on both the NetVault Backup Server and the Client. NetVault Backup 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 Backup message channels	Ports for sending messages during data transfers. Configure this option on both the NetVault Backup Server and the Client. NetVault Backup 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 Backup Server (on which the plug-in is installed) when a firewall separates an NDMP filer and the NetVault Backup Server. By default, NetVault Backup uses port number 10000. You can change it, if necessary.
Listen ports for NDMP data channels	Ports to listen on for NetVault Backup devices operating as NDMP movers. Configure this option on the NetVault Backup 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 Backup 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:

•

A comma-separated list (example: 20000, 20050)

•

A port-range separated by a dash (example: 20000-20100)

•

A combination of comma-separated list and port-range (example: 20000-20100, 20200)


	NOTE: You must configure the same port-range for data, message, and broadcast channels across all NetVault Backup machines.

IMPORTANT:

•

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

•

NetVault Backup uses port number 20031 for TCP and UDP messaging. Make sure that this port is open on the firewall.
