Firewall filtering rules

When creating firewall rules on the server and client machines, make sure that you open the following ports to send and receive traffic from NetVault.

 
* 
IMPORTANT: MSP administrator can create Server to Client firewall rules and Tenant administrator can create Client to Server firewall rules.

Firewall configuration example

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

•
Number of drives: 6
•
Number of clients with one plug-in: 10
•
Number of clients with two plug-ins: 2

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.

To locate and add a client that is not discovered automatically:
1
Start the client addition wizard, and then click Find Machine.
2
On the Find Client page, type the Fully Qualified Domain Name (FQDN) or IP address of the client, and click Find.
3
After the machine is located, complete Step 2 through Step 5 in the section Adding a client to the NetVault Server.
 
* 
NOTE: NetVault reports an error if it fails to locate the specified client on the network. An error can occur for reasons such as the following:
•
The NetVault software is not installed on the machine.
•
The NetVault Service is not running on the machine.
•
The DNS lookup table or the machine’s host table cannot be contacted.

Checking communication through a firewall

When adding a client that resides outside the firewall, you can perform a firewall test to check if the server and client can communicate through the firewall. You can also perform this test to check connectivity for existing clients.

To check if the server and client can communicate through a firewall:
1
To check connectivity for new clients, start the client addition wizard, and then click Firewall Test.
— or —
To check connectivity for existing clients, open the Manage Clients page. Select the client, and then click Firewall Test.
2
In the Check Connection dialog box, provide the following details.
 
Table 22. Check connection
Option
Description

NetVault Client Name

For new clients, type the NetVault name of the machine.

For existing clients, the name is displayed as a read-only property.

NetVault Client Address

For new clients, type the IP address of the machine.

For existing clients, the IP address is displayed as a read-only property.

UDP Port

The default UDP port for NetVault. It is set to 20031. If you have configured NetVault to use a different port, change this value.

TCP Port

The default UDP port for NetVault. It is set to 20031. If you have configured NetVault to use a different port, change this value.

Timeout

The timeout interval is set to 15 seconds by default.

3
Click Test. This command checks if TCP, UDP, and messaging connectivity is available between the server and client, and displays the result in the dialog box.
 
* 
IMPORTANT: The firewall test option checks the connectivity to the Stats Manager process on the specified server or client machine. If this process is not running on the client, the test fails. However, the client may still be accessible for backup. In any case, it is an abnormal situation and should be corrected.
