What Are the Typical Scenarios of IPsec VPN?

A VPN is a point-to-point connection that implements private network access between two points.

Applicable scenarios:
- A VPN is created between different regions to enable cross-region VPC communications.
- A VPN is created between VPCs of Huawei Cloud and another cloud, for example, Alibaba Cloud.
- A VPN is created between a VPC of Huawei Cloud and an on-premises data center.
- VPN HUB works together with VPC peering connections and Cloud Connect connections to enable communications between an on-premises data center and multiple VPCs on the cloud.
- VPN works with SNAT to access specific IP addresses across clouds.
Not applicable scenarios:
- A VPN cannot be used to connect VPCs in the same region. It is recommended that you use VPC peering connections to enable communications between VPCs in the same region.
- A VPN cannot be used between the cloud and your home network that uses PPPoE dial-up.
- A VPN cannot be used between the cloud and 4G/5G routers.
- A VPN cannot be used between the cloud and your personal terminals.
