Setting Up a Network Gateway Connection Using a Predefined Network Topology

If you are setting up group-to-group network connectivity through a network gateway, consider using a network topology instance.

Note: With the topology for a network gateway connection, you can configure multiple client computers to provide a single logical network gateway function. When internal and external clients establish a connection to the logical network gateway, the communication is bi-directional.

Before You Begin

  • Set up the Commvault network gateway.
  • The network topology instance requires the following client groups. For information about how to create a group, see Adding or Editing a Server Group.
    • An infrastructure group, to will contain the CommServe server and internal MediaAgents.
    • A client group, to contain all clients.
    • A network gateway client group, to be the network gateway client.
  • You must have administrative management permissions on the client groups that you plan to use in the network topology instance.
  • If some clients in the network gateway client group belong to other client groups that are not designated for network gateway connections, then the network gateway settings on the clients might be deleted. To prevent this issue, select the This computer is in DMZ and will work as a network gateway check box option for the clients in the network gateway client group. See Configuring Commvault Network Gateway.
  • Note the following regarding port requirements:
    • Tunnel port: Default = 8403 (CVD port plus 3) should be open on the network gateway. If you want to change the default tunnel port, see Updating Incoming Ports on Client Computers.
    • Servers/laptops and infrastructure computers should be able to open connections to network gateway on the tunnel port.

Procedure

  1. From the navigation pane, go to Manage > Network > Network Topologies.

    The Network topologies page appears.

  2. Click Add topology.

    The Add topology dialog box appears.

  3. In the Name box, enter a name for this instance of a network gateway connection.
  4. For Client type, select the type of client that you will include in the topology:
    • If the clients are servers, select Servers.
    • If the clients are laptops that need to connect to servers, select Laptops.
  5. From the Topology type list, select Network Gateway.
  6. Select the server groups:

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

    * If the Client type is set to Servers, do the following:

    1. In the Servers list, select a server group that will initiate connections to the network gateway group.
    2. In the DMZ gateways list, select the server group that you want to designate as the network gateway group.
    3. In the Infrastructure machines list, select another server group that will initiate connections to the network gateway group.

    * If the Client type is set to Laptops, do the following:

    1. In the Laptops list, select a laptop group that will initiate connections to the network gateway group.
    2. In the Infrastructure machines list, select a server group that will initiate connections to the network gateway group.
    3. In the DMZ gateways list, select the server group that you want to designate as the network gateway group.
  7. Review the Laptops will automatically use network gateways to connect to all Infrastructure machines check box as follows:
    • 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. All traffic originating from clients in the Servers group (if Client type is set to Servers) or the Laptops group (If Client type is set to Laptops) list 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 group. Otherwise, you must set up direct network routes from the clients to the MediaAgents.
      • If a client communicates with MediaAgents (or a CommServe server) that are not part of the Infrastructure group or that have not been configured with other network routes, communications with the MediaAgent (or CommServe server) will fail.
  8. Click Save.

What to Do Next

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.
