      VPN Gateway IP of Connection 2

      Standby EIP of the VPN gateway.

      2.2.2.2

      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 of the connection configured on the customer gateway.

      Test@123

      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: 192.168.0.0/16
      • Destination CIDR Block: 172.16.1.1/32

      Policy Settings

      The policy settings must be the same as those on TheGreenBow VPN Client.
      • IKE Policy
        • Encryption Algorithm: AES-256
        • Authentication Algorithm: SHA2-256
        • DH Algorithm: Group 15
        • Version: v2
        • Lifetime (s): 7200
        • Local ID: IP Address
        • Customer ID: IP Address
      • IPsec Policy
        • Encryption Algorithm: AES-256
        • Authentication Algorithm: SHA2-256
        • PFS: DH group 15
        • Transfer Protocol: ESP
        • Lifetime (s): 3600

      Connection 2's Configuration

      Determine whether to enable Same as that of connection 1.
