ECS One ECS in the service VPC. The ECS is used to verify communications between the cloud and the on-premises data center. If you have multiple ECSs associated with different security groups, you need to add rules to the security groups to allow network access.
Three ECS instances have been deployed in the VPC where the VPN gateway is located to simulate resource nodes on the cloud. In this example, the flavor of each ECS is c6.large.2 (2 vCPUs, 4 GB memory, CentOS 8.0 - 64-bit system image).
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
Run the following command on the ECS: ping 172.16.0.100 172.16.0.100 is the IP address of a server in the on-premises data center. Replace it with an actual server IP address.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
To check whether such a security group has been configured, choose Compute > Elastic Cloud Server, click an ECS name, click the Security Groups tab, and click Manage Rule. Verify that a security group permits data flows from the customer subnet to the ECSs on Huawei Cloud.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
XX.XX.XX.XX indicates the private IP address of the ECS to be connected. Replace it with the actual private IP address.
