      Standby EIP

      EIP 2 used by the VPN gateway to communicate with the on-premises data center.

      2.2.2.2

  4. Configure a customer gateway.

    1. Choose Virtual Private Network > Enterprise – Customer Gateways, and click Create Customer Gateway.
    2. Set parameters as prompted.

      The following table only describes the key parameters for creating a customer gateway. For other parameters, use their default settings.

      Table 2 Customer gateway parameters

      Parameter

      Description

      Value

      Name

      Name of a customer gateway.

      cgw-hillstone

      Identifier

      Select IP Address, and enter the IP address used by the Hillstone firewall to communicate with the Huawei Cloud VPN gateway.

      IP Address

      1.1.1.1

  5. Configure VPN connections.

    In this scenario, a VPN connection is established between the Hillstone firewall and the primary EIPs of the Huawei Cloud VPN gateway and primary EIP2.
    1. Choose Virtual Private Network > Enterprise – VPN Connections, and click Buy 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.

      Table 3 VPN connection parameters

      Parameter

      Description

      Value

      Name

      VPN connection name.

      vpn-001

      VPN Gateway

      VPN gateway for which the VPN connection is created.

      vpngw-001

      VPN Gateway IP of Connection 1

      Active EIP of the VPN gateway.

      1.1.1.2

      Customer Gateway of Connection 1

      Customer gateway of connection 1.

      1.1.1.1

      2.2.2.2

      Customer Gateway of Connection 2

      Customer gateway of connection 2.

      1.1.1.1

      VPN Type

      Select Policy-based.

      Policy-based

      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.

      172.16.0.0/16

      Connection 1's Configuration

      Configure the PSK, confirm PSK, and policies for the VPN gateway IP address of connection 1.

      Set parameters based on the site requirements.

      PSK, Confirm PSK

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

      Set parameters based on the site requirements.

      Policy

      A policy rule defines the data flow that enters the encrypted VPN connection between the local and customer subnets. You need to configure the source and destination CIDR blocks in each policy rule.

      • Source CIDR Block

        The source CIDR block must contain some local subnets. 0.0.0.0/0 indicates any address.

      • Destination CIDR Block

        The destination CIDR block must contain all customer subnets.
      • Source CIDR block 1: 192.168.0.0/24
      • Destination CIDR block 1: 172.16.0.0/16
      • Source CIDR block 2: 192.168.1.0/24
      • Destination CIDR block 2: 172.16.0.0/16

      Policy Settings

      The policy settings must be the same as those on the Hillstone firewall.
      • IKE Policy
        • Version: v1
        • Negotiation Mode: Main
        • Authentication Algorithm: SHA2-256
        • Encryption Algorithm: AES-256
        • DH Algorithm: Group 15
        • Lifetime (s): 86400
        • Local ID: FQDN(hwvpn.abc.efg)
        • Customer ID: FQDN(hillstone.abc.efg)
      • IPsec Policy
        • Authentication Algorithm: SHA2-256
        • Encryption Algorithm: AES-256
        • PFS: DH group 15
        • Transfer Protocol: ESP
        • Lifetime (s): 28800

      Connection 2's Configuration

      Determine whether to enable Same as that of connection 1.

      NOTE:

      It is recommended that the configuration of connection 2 be the same as that of connection 1.
