How Many VPN Connections Do I Need to Connect Multiple On-premises Servers to the Cloud?
Huawei Cloud VPN uses IPsec VPN technology. It connects a VPC on the cloud and your on-premises data center. Therefore, the number of VPN connections is irrelevant to the number of servers to be connected to the cloud, but to the number of data centers where the servers are located.
Two EIPs can be bound to a VPN gateway for communication with a customer gateway.
- If an on-premises data center has only one egress gateway, all servers or hosts in the data center connect to the Internet through this gateway. In this case, you need to configure a VPN connection group consisting of two VPN connections. That is, configure a VPN connection for each of the two EIPs of the VPN gateway to communicate with the egress gateway in the on-premises data center.
- If an on-premises data center has two egress gateways, the servers or user hosts in the data center connect to the Internet through the tow egress gateways. In this case, you need to configure two VPN connection groups, each of which consisting of two VPN connections. That is, configure a VPN connection for each of the two EIPs of each VPN gateway to communicate with both egress gateways in the on-premises data center.
