You need to implement several steps to make the IPsec VPN connection effective, and then you can perform full self-configuration of IPsec VPN in the console. An example is given below.
Example
Through IPsec VPN Connections, establish communication between subnet A (192.168.1.0/24) in your VPC TomVPC in City 1 and the subnet (10.0.1.0/24) in your IDC. Assume the public IP of the VPN gateway in your IDC is 202.108.22.5.
