Procedure
Prerequisites
- Cloud side
- A VPC has been created. For details about how to create a VPC, see Creating a VPC and Subnet.
- Security group rules have been configured for the VPC, and ECSs can communicate with other devices on the cloud. For details about how to configure security group rules, see Security Group Rules.
- Data center side
- IPsec has been configured on the VPN devices in the two on-premises data centers. For details, see Administrator Guide.
- The remote subnets of the VPN device in on-premises data center 1 must contain the local subnet of the Huawei Cloud VPC and the subnet to be interconnected in on-premises data center 2. The remote subnets of the VPN device in on-premises data center 2 must contain the local subnet of the Huawei Cloud VPC and the subnet to be interconnected in on-premises data center 1.
Procedure
Huawei Cloud VPNs support static routing mode, BGP routing mode, and policy-based mode. The following uses the static routing mode as an example.
- Configure a VPN gateway.
- Choose Virtual Private Network > Enterprise – VPN Gateways, and click Buy VPN Gateway.
- Set parameters as prompted.
