What Configurations Are Required at Both Ends of a VPN That Connects an On-premises Data Center to a VPC?

To implement the VPN interconnection, create a VPN on the cloud and configure the VPN device in the on-premises data center.

  • Create a VPN on the cloud.
    • Buy a VPN gateway, and configure the billing mode, bandwidth, and interconnected VPC.
    • Create a customer gateway and configure the routing mode.
    • Buy a VPN connection, and configure the gateway IP addresses and subnets at both ends, as well as negotiation policies.
  • Configure the VPN device in the on-premises data center.
    1. Configure the public IP address used by the on-premises data center to connect to the cloud, and complete the configurations of IPsec negotiation phase 1 and phase 2 on the VPN device.
    2. Configure routes, NAT, and security policies on the VPN device.
