Configuration on the Cloud Console

Prerequisites

A VPC and its subnets have been created on the management console.

Procedure

Log in to Huawei Cloud management console.
Choose Networking > Virtual Private Network.

Configure a VPN gateway.

Choose Virtual Private Network > Enterprise – VPN Gateways. On the S2C VPN Gateways tab page, click Buy S2C VPN Gateway.

Set parameters as prompted and click Buy Now.

Table 1 only describes the key parameters for configuring a VPN gateway. For other parameters, use their default settings.

**Table 1** Key parameters for creating a VPN gateway
Parameter	Description	Value
Name	Name of a VPN gateway.	vpngw-001
Associate With	Select VPC.	VPC
VPC	Huawei Cloud VPC that the on-premises data center needs to access.	vpc-001(192.168.0.0/16)
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	Huawei Cloud VPC subnet that needs to communicate with the VPC of the on-premises data center.	192.168.0.0/24 192.168.1.0/24
BGP ASN	BGP AS number.	64512
HA Mode	Working mode of the VPN gateway.	Active-active
Active EIP	EIP 1 used by the VPN gateway to communicate with the on-premises data center.	1.1.1.2
Standby EIP	EIP 2 used by the VPN gateway to communicate with the on-premises data center.	2.2.2.2

Create a customer gateway.

Choose Virtual Private Network > Enterprise – Customer Gateways, and click Create Customer Gateway.

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

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.

Choose Virtual Private Network > Enterprise – VPN Connections, and click Buy VPN Connection.

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.
