What is VPN Gateway

Last Updated: Oct 23, 2017

VPN Gateway is an Internet-based service that establishes a safe and reliable connection between a VPC and your on-premises data centers using a VPN tunnel.

Alibaba Cloud supports Internet Protocol security (IPsec) VPN connections.

Note: Alibaba Cloud VPN Gateway provides services in accordance with the relevant national policies and regulations. It does not provide Internet access.

VPN Gateway is made up of the following components:

  • VPN gateway

    The VPN gateway is the IPsec VPN gateway created on the Alibaba Cloud side. One VPN gateway can have multiple VPN connections.

    Note: VPN gateways can only be used in a VPC network. They cannot be used in the classic network.

  • Customer gateway

    The customer gateway is the VPN service deployed in your on-premises data center. By creating a customer gateway, you can register the IDC VPN information to the cloud, and then create a VPN connection to connect the VPN gateway and the customer gateway.

  • VPN connection

    The VPN connection is an encrypted VPN tunnel established between a customer gateway and a VPN gateway.

    On-premise data centers can initiate an encrypted communication with a VPC only when the VPN connection is established.
