Setting Up a Two-Way Direct Connection Using a Predefined Network Topology

You can create a network topology instance in which members of either client group can connect to members of the other client group.

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.

  • Both DMZ servers/infrastructure computers and servers/laptops should be able to open connections to each other on the tunnel port.


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

  2. The Network topologies page appears.

  3. Click Add topology.

    The Add topology dialog box appears.

  4. In the Name field, enter a name for this instance of a two-way direct connection.

  5. For Client type, select Servers.

  6. From the Topology type list, select Two-way.

  7. Click Next.

  8. From the Servers list, select the server group that will initiate connections with members of the Infrastructure machines group.

  9. Optional: Click the advanced toggle to edit the following options:

    • Tunnel port. Set this to Default (8403), or 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 enter another interval. To avoid idle session timeouts on cloud-based clients, set the interval to 200 seconds or less.

  10. From the Infrastructure machines list, select the a server group that will initiate connections with members of the Servers group.

  11. Optional: To edit the Tunnel port and Keep-alive interval options, as described in Step 9, above.

  12. Click Next.

  13. Optional: Edit the following advanced 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).

  14. Click Submit.
