          VPN FAQs

          What are the scenarios supported by VPN?

          The VPN gateway of Baidu AI Cloud supports the users' establishment of site-to-site VPN tunnel interconnection. The Baidu AI Cloud network and the user IDC network are connected by the encrypted tunnel of the public network to help users to construct the hybrid cloud environment, and realize the resource sharing between the data center and the cloud. The users can also realize the enterprise data backup and remote disaster recovery by the VPN gateway to guarantee the high availability of data and services.

          What are the advantages of the VPN of Baidu AI Cloud?

          VPN supports the bandwidth as high as 1G; based on the HA mode, the automatic failover and recovery realizes high reliability.

          Can only one segment communicate although the tunnel status is available after multiple segments are configured for the VPN tunnel?

          Baidu AI Cloud and the opposite terminal devices (such as strongswan) have different multi-segment implementation modes. You can merge multiple segments or use 0.0.0.0/0.

          Can one VPC connect with multiple IDCs by VPN?

          Yes. Currently, multiple VPN gateways can be established for the VPC of private network, and one VPN channel is established on each VPN network. In this way, multiple user IDCs can be connected.

          What is the quality of the network connected by VPN?

          The private network and IDC are connected by the public network. Depending on the network quality of the public network, the time delay, packet loss, buffeting problems may occur. If you need a more stable communication quality, you are recommended to use the dedicated access services. The VPN background will monitor the network quality throughout the day, including keepalive and network time delay. In case of any network abnormalities, the operation and maintenance staff will timely process them. You can also monitor the traffic status of the VPN gateway and channel in the console in real time. Please contact us timely if finding any abnormalities.

          Which encryption protocols does the VPN support?

          Currently, the VPN connection supports the IPSec encryption protocol to meet the demands of most VPN connections.

          How to realize the access of some cloud servers in VPC by VPN?

          The VPN gateway of Baidu AI Cloud belongs to the private network VPC services, and can realize the subnet-level VPN tunnel interconnection. You can plan the opposite terminal cloud server connected by VPN in one subnet, and then configure the source segment to specify this subnet in the local network and route table entries of the VPN gateway, so as to realize that only the cloud server in the specified subnet in one VPC can access by VPN.

          Can VPN realize the interconnection between two VPCs?

          Yes. You should respectively purchase VPN gateways and configure VPN gateways in two VPC. The operation is relatively complex, and we recommend you to use the peer connection services. The peer connection connects two VPC by the backbone network of Baidu AI Cloud, so the communication quality can be better guaranteed.

          Does the VPN gateway of Baidu AI Cloud support SSL VPN?

          No, it doesn't currently. You can purchase a third-party image in the cloud market to realize SSL VPN.
