VPN Gateway provides network connection services that securely and reliably connect data centers, office networks, and Internet clients to Alibaba Cloud through encrypted and private tunnels. This way, on-cloud and on-premises resources can securely access each other.
Network connection scenarios
VPN Gateway supports IPsec-VPN and SSL-VPN connections. These types of connections are applicable to different network connection scenarios.
IPsec-VPN
You can use IPsec-VPN to establish connections between Alibaba Cloud and data centers or office networks. The following two network connection scenarios are supported:
You want to establish connections between virtual private clouds (VPCs) and data centers or office networks. After connections are established, data centers or office networks can directly access the resources in the connected VPCs.
You want to establish connections between Alibaba Cloud transit routers and data centers or office networks. After connections are established, data centers or office networks can communicate with other networks under the connected transit routers to access resources on other networks.
For more information, see What is IPsec-VPN?
Communication with VPCs
Communication with other networks connected to transit routers
SSL-VPN
SSL-VPN is ideal for establishing network connections between Internet clients (remote clients) and Virtual Private Cloud (VPC). After such network connections are established, Internet clients can access the resources in the connected VPCs. For more information, see What is SSL-VPN?
