Setting Up Network Gateway Connections Using a Predefined Network Topology

The Commvault software simplifies the network configuration by providing predefined network topology types that you can use when setting up connectivity between client groups. The client groups use a network topology instance to establish connections between themselves.

If you are setting up group-to-group network connectivity through a network gateway, consider using the network topology for network gateway connections. During the configuration of the network topology instance, you will need to designate three client groups to be used for internal clients, external clients, and network gateway clients.

Before You Begin

• Create the following three client groups to be used in the network gateway topology, as follows:

  • An infrastructure group, which will contain the CommServe server and internal MediaAgents.

  • A client group, which will contain all clients.

  • A network gateway client group, which will act as a network gateway client.

• You must have administrative management permissions on the client groups that you plan to use in the network topology instance.

Procedure

1. From the CommCell Browser, right-click Network Topologies > New Topology.

   The Network Topology dialog box is displayed.

2. In the Topology Name box, enter a name for this instance of a network gateway arrangement.

3. Optional: In the Description box, enter a description for this topology.

4. In the Client Type list, choose the type of client that you will include in the topology, as follows:

   • Servers: Click if your clients are servers.

   • Laptops: Click if your clients are laptops that need to connect to servers.

5. For Topology Type, click Network Gateway.

6. If Client Type is set to Servers, do the following:

   Note

   See Using a Smart Network Topology When Setting Up Network Connections.

   1. In the Servers list, select a client group that will initiate connections to the Infrastructure gateways group.

   2. In the DMZ gateways list, select the client group that you want to designate as the network gateway group.

   3. In the Infrastructure machines list, select another client group that will initiate connections to the Infrastructure gateways group.

7. If Client Type is set to Laptops, do the following:

   Note

   See Using a Smart Network Topology When Setting Up Network Connections.

   1. In the Laptops list, select a client group that will initiate connections to the Infrastructure gateways group.

   2. In the DMZ gateways list, select the client group that you want to designate as the network gateway group.

   3. In the Infrastructure machines list, select a laptop group that will initiate connections to the Infrastructure gateways group.

8. Review the Force servers to use network gateways for all traffic (for Servers) or the Laptops will automatically use network gateways to connect to all Infrastructure machines (for Laptops) check box:

   Important

   If you use third-party port mappings (TPPM) or Commvault VPN services, you must clear the check box.

   • To allow external clients to communicate directly with other hosts, clear the check box or define network routes to the other hosts.

     By default, all traffic originating from clients in the Servers list (for Servers) or the Laptops list (for Laptops) will use network routes when communicating with any other host.

   • If the check box is selected, review the following considerations:

     • The CommServe host and all MediaAgent hosts (that communicate with members of the Servers group must be in the selected Infrastructure machines group. Otherwise, you must define network routes to the other hosts.

     • If a client communicates with MediaAgents (or a CommServe server) that are not part of the Infrastructure machines group or that have not been configured with other network routes, communications with the MediaAgent (or CommServe server) will fail.

     • If you make changes to the Servers, you do not need to push the network configuration.

9. To encrypt network traffic, select Encrypt network traffic.

10. Click OK.

What to Do Next

1. Set up the Commvault network gateway. For more information, see Setting up the Commvault network gateway.

2. If your clients do not have the Commvault software installed, install the Commvault software on the clients that will be part of the network topology.

   During the client installation, configure the client to connect to the CommServe computer through a network gateway. For network settings instructions during the installation, see Setting Up Connectivity to the CommServe Computer Using a Network Gateway.

   Note

   Make sure to assign the client to the Servers that you defined in the topology.

3. From the CommCell Browser, right-click the network topology that you configured, click Push Network Configuration, and then click OK.

You can configure additional advanced network settings, such as the Default Outgoing Tunnel Protocol option or the Number of Tunnels per Route, at the client computer group level. For information about the available settings, see Incoming Ports and Options. For information about accessing the client computer group network settings, see Configuring Network Settings.
