Configuration on the Cloud Console

Prerequisites

      Interconnection Subnet

      Subnet used for communication between the VPN gateway and the VPC of the on-premises data center. Ensure that the selected interconnection subnet has four or more assignable IP addresses.

      192.168.2.0/24

      Local Subnet

      Subnets of the Huawei Cloud VPC that needs to communicate with the VPC of the on-premises data center.

      HA Mode

      Working mode of the VPN gateway.

      Active-active

      Active EIP

      EIP 1 used by the VPN gateway to access the on-premises data center.

      1.1.1.2

      Standby EIP

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

      2.2.2.2

  4. Create a customer gateway.

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

      Table 2 describes the parameters for creating a customer gateway.

      Table 2 Parameters for creating a customer gateway

      Parameter

      Description

      Value

      Name

      Name of a customer gateway.

      cgw-ar

      Identifier

      Select IP Address, and enter the public IP address of the AR router.

      IP Address

      1.1.1.1

      BGP ASN

      BGP AS number of the AR router.

      65000

  5. Create VPN connections.

    In this scenario, a VPN connection is created between the AR router and each of the active EIP and active EIP 2 of the VPN gateway.
    1. Choose Virtual Private Network > Enterprise – VPN Connections, and click Buy VPN Connection.
    2. Create VPN connection 1.

      Table 3 describes the parameters for creating a VPN connection.

      Table 3 Parameter settings for VPN connection 1

      Parameter

      Description

      Value

      Name

      Name of a VPN connection.

      vpn-001

      VPN Gateway

      VPN gateway for which the VPN connection is created.

      vpngw-001

      Gateway IP Address

      Active EIP bound to the VPN gateway.

      1.1.1.2

      Customer Gateway

      Name of a customer gateway.

      cgw-ar

      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 and 214.0.0.0/8 cannot be used as customer subnets.

      172.16.0.0/16

      PSK, Confirm PSK

      The value must be the same as the PSK of the connection configured on the customer gateway device.

      Set this parameter 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 firewall.
      • IKE Policy
        • Version: v2
        • Authentication Algorithm: SHA2-256
        • Encryption Algorithm: AES-128
        • DH Algorithm: Group 14
        • Lifetime (s): 86400
        • Local ID: IP Address
        • Customer ID: IP Address
      • IPsec Policy
        • Authentication Algorithm: SHA2-256
        • Encryption Algorithm: AES-128
        • PFS: DH group 14
        • Transfer Protocol: ESP
        • Lifetime (s): 3600
    3. Create VPN connection 2.

      For VPN connection 2, you are advised to use the same parameter settings as VPN connection 1, except the parameters listed in the following table.

      Table 4 Parameter settings for VPN connection 2
