IPsec VPN¶
Internet Protocol Security (IPsec) VPN uses a secure network protocol suite that authenticates and encrypts the packets of data to provide secure encrypted communication between different networks.
In the example shown in Figure 1, assume that you have created a VPC with two subnets (192.168.1.0/24 and 192.168.2.0/24) on the cloud, and the router in your on-premises data center also has two subnets (192.168.3.0/24 and 192.168.4.0/24). In this case, you can create a VPN to connect the VPC subnets and the data center subnets.

Site-to-site VPN is supported to enable communication between VPC subnets and on-premises data center subnets.
