Configuring ports

  1. Because the Double-Take Availability for VMware Infrastructure console uses SSH to communicate with the VMware ESX host(s), and the ESX hosts also use it to connect to each other, you must configure SSH port communication on both your source and target ESX servers.
    1. Using the VMware Virtual Infrastructure Client, select the host ESX server.
    2. On the Configuration tab, select Security Profile.
    3. In the Firewall Properties, verify that SSH Client is selected and click OK.
    4. Verify that the Configuration tab shows that SSH Client is enabled for the host on port 22.
    5. In the Firewall Properties, verify that SSH Server is selected and click OK.
    6. Verify that the Configuration tab shows that SSH Cerveris enabled for the host on port 22.
  2. Open port 443 on both your source and target ESX servers for HTTPS communication. You also need to open this port on your VirtualCenter server.

  3. Open port 6331 on the machine running the Double-Take Availability for VMware Infrastructure service.

    If the Double-Take Availability for VMware Infrastructureconsole and the Double-Take Availability for VMware Infrastructure service are on separate machines, the machines cannot be separated by a firewall because Microsoft .NET remoting is required, which is not compatible with a firewall configuration.
