- Configure a customer gateway.
- Choose Virtual Private Network > Enterprise – Customer Gateways, and click Create Customer Gateway.
- Set parameters as prompted.
Table 2 only describes the key parameters for creating a customer gateway. For other parameters, use their default settings.
Table 2 Parameters for creating a customer gateway Parameter
Description
Value
Name
Name of a customer gateway.
cgw-ali
Identifier
- IP Address: Specify the IP address of the customer gateway.
- FQDN: Set the fully qualified domain name (FQDN) to a string of 1 to 128 case-sensitive characters that can contain letters, digits, and special characters (excluding &, <, >, [, ], \, ?, and spaces).
If the customer gateway does not have a fixed IP address, select FQDN.
NOTE:Ensure that an ACL rule has been configured on the customer gateway device to permit UDP port 4500.
IP Address

- Configure VPN connections.
In this scenario, the Alibaba Cloud VPN gateway has only one IP address. A VPN connection needs to be created between each of the two active EIPs of the Huawei Cloud VPN gateway and the IP address of the Alibaba Cloud VPN gateway.
- Choose Virtual Private Network > Enterprise – VPN Connections, and click Create VPN Connection.
- Set parameters as prompted.
Table 3 only describes the key parameters for creating VPN connections. For other parameters, use their default settings.

Select BGP routing.
BGP routing
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.
172.16.0.0/24
Connection 1's Configuration
