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.

• Creating a VPN on the cloud: Buy a VPN gateway by selecting the billing mode, VPC, and bandwidth. Buy a VPN connection by specifying the gateway IP addresses, subnets, and negotiation policies at both ends.
• Configuring the on-premises VPN device: Select the public IP address on the on-premises data center side, complete configurations of IPsec negotiation phases 1 and 2 on the device that supports IPsec VPN, and then configure network routes, NAT, and security rules.
