Setting Up a One-Way Direct Connection (Client to Server) Using a Predefined Network Topology - Client Type is Laptops


You can create a network topology instance in which members of one client group can connect to members of another client group.

Use this configuration on environments in which the client (of type laptops) initiates connections to one or more of server computers, such as the CommServe computer or a MediaAgent.

Before You Begin

  • Verify that the client groups that you want to use in the network topology instance are already defined in the CommCell Console or the Command Center.

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

  • Servers and laptops should be able to open connections to the DMZ servers/infrastructure machines on the tunnel port.


  1. From the Command Center 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 field, enter a name for this instance of a one-way direct connection.

  4. For Client type, select Laptops.

  5. From the Topology type list, select One-way.

  6. Perform the following steps:

    1. From the Laptops list, select the group that will initiate connections with members of the infrastructure machines group.

    2. Optional: Click the down arrow next to the Laptops list to edit the following options:

      • Tunnel port. Set this to Default (8403), or click the edit icon to enter another port number.

      • Keep-alive interval. The interval (in seconds) for sending keep-alive packets, to maintain the session if backup traffic has an extended pause. Set this to 180 (default), or click the edit icon to enter another interval. To avoid idle session timeouts on cloud-based clients, set the interval to 200 seconds or less.

    3. From the Infrastructure machines list, select a group that will receive connection requests from members of the laptops group.

    4. Optional: Edit the Tunnel port and Keep-alive interval, as described above.

  7. Optional: Move the Advanced toggle key to the right to edit the following options:

    • Move the Encrypt traffic toggle key to the right to encrypt network traffic (HTTPS).

    • Select Encrypted, Authenticated, Regular, or Raw from the tunnel protocol list.

    • Select the Parallel data transfer streams for long distance networks (default value is 1, and maximum value is 8).

  8. Click Save.
