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 device in the on-premises data center. For details, see Administrator Guide.
