EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, load balancers, and NAT gateways. Virtual Private Cloud (VPC): an isolated and private virtual network environment.
Access to the public network from a workload: You can configure source network address translation (SNAT) rules in NAT Gateway, so that containers can access the public network. "Workload Network Access" > "Accessing Public Networks from a Container" in the User Guide.
Check whether an EIP has been bound to the ECS (node) or whether the ECS has a NAT gateway configured. Figure 1 shows that an EIP has been bound. If no EIP is displayed, bind an EIP to the ECS.
If the local host communicates with the ECS using NAT, this problem may occur. Run the following command to check whether tcp_tw_recycle is enabled on the ECS: sysctl -a|grep tcp_tw_recycle If the value of tcp_tw_recycle is 1, the function is enabled.
If there are no NAT gateways, CCE Autopilot automatically creates a NAT gateway with default specifications, binds an EIP to the NAT gateway, and configures SNAT rules. The NAT gateway will be billed. For details, see NAT Gateway Billing. Click Next: Select Add-on.
*:get View details about all NAT Gateway resources. nat:*:list List all NAT Gateway resources. kms:cmk:get Query key information. kms:cmk:list List all keys.
This rule is required only when the SAP HANA Studio is deployed on a Windows ECS. 10.0.0.0/24 TCP 80 (HTTP) Allows users to access the NAT server using Hypertext Transfer Protocol (HTTP). 10.0.0.0/24 TCP 443 (HTTPS) Allows users to access the NAT server using Hypertext Transfer Protocol
Implementing Public Network and Cross-VPC Access for CAE Applications Through a NAT Gateway This section describes how to use a NAT gateway to implement public network and cross-VPC access for CAE applications.
You can bind an EIP or NAT gateway to perform operations in this function.
detection fail: NAT detailed failed. fragment packet limit: Fragment packets exceed the limit. fragment packet reassemble timeout: Fragment packet reassembly times out.
The NAT mapping IP address of the customer server is 22.22.22.22 and the local subnet is 192.168.222.0/24. The ECS IP address and the customer server IP address are 192.168.200.200 and 192.168.222.222, respectively.
NAT ReadOnlyAccess Read-only permissions for NAT Gateway. SecMaster_Agency Used to obtain asset information in NAT Gateway for asset information synchronization in the asset management scenario. VPC FullAccess All permissions for VPC.
Public subnet: A NAT ECS allows you to access SAP Business One nodes using SSH. An SAP HANA Studio ECS is an ECS running the SAP HANA Studio software. You can use the Remote Desktop Protocol (RDP) or SSH to access the SAP HANA Studio ECS and manage the SAP HANA database.
Public subnet: Network Address Translation (NAT) instance ECS: allows you to access SAP HANA nodes using SSH. SAP HANA Studio ECS: runs the SAP HANA Studio software. You can use RDP or SSH to access the SAP HANA Studio ECS and manage the SAP HANA system.
You can easily bind an EIP to an ECS, BMS, virtual IP address, NAT gateway, or load balancer, enabling immediate Internet access. Scalable File Service (SFS) Turbo: SFS Turbo provides a fully hosted shared file storage, which is expandable to 320 TB.
NAT is disabled.
NAT gateway Yes No 1 oms_cluster_nat_Cluster ID This NAT gateway enables list and migration nodes to communicate with migration sources over the public network, so that source data can be migrated.
NAT gateway Yes No 1 oms_cluster_nat_Cluster ID This NAT gateway enables list and migration nodes to communicate with migration sources over the public network, so that source data can be migrated.
Check Item 4: NAT Gateway + Port Generally, no EIP is configured for the backend server of NAT. Otherwise, exceptions such as network packet loss may occur.
You can easily bind an EIP to a FlexusX instance, ECS, BMS, virtual IP address, NAT gateway, or load balancer, enabling immediate Internet access. Virtual Private Cloud (VPC): VPC allows you to isolate online resources with virtual private networks.
