  5. Configure VPN connections.

    In this scenario, a VPN connection is created between the Hillstone firewall and the primary EIP of the Huawei Cloud VPN gateway, and another VPN connection is created between the Hillstone firewall and the secondary EIP of the Huawei Cloud VPN gateway.
    1. Choose Virtual Private Network > Enterprise – VPN Connections, and click Create VPN Connection.
    2. Set parameters as prompted.

      The following table only describes the key parameters for creating VPN connections. For other parameters, use their default settings.

      Customer Subnet

      Subnet in the on-premises data center that needs to access the VPC on Huawei Cloud.

      • A customer subnet cannot be included in any local subnet or any subnet of the VPC to which the VPN gateway is attached.
      • Reserved VPC CIDR blocks such as 100.64.0.0/10, 100.64.0.0/12, and 214.0.0.0/8 cannot be used as customer subnets. The reserved CIDR blocks vary according to regions and are subject to those displayed on the console.

        If you need to use 100.64.0.0/10 or 100.64.0.0/12, submit a service ticket.

      Connection 1's Configuration

      Configure the IP address assignment mode of tunnel interfaces, local tunnel interface address, customer tunnel interface address, PSK, confirm PSK, and policies for connection 1.

      Set parameters based on the site requirements.

      Interface IP Address Assignment
      • Manually specify

        In this example, Manually specify is selected.

      • Automatically assign

      PSK, Confirm PSK

      The value must be the same as the PSK of the connection configured on the firewall.

      Set parameters based on the site requirements.

      Policy Settings

      The policy settings must be the same as those on the firewall.
      • IKE Policy
        • Version: v1

      Connection 2's Configuration

      Determine whether to enable Same as that of connection 1.

      NOTE:

      If you disable Same as that of connection 1, you are advised to use the same settings as connection 1 for connection 2, except the local and customer tunnel interface addresses.

      Disabled

      Local Tunnel Interface Address
