If CDM needs to access a local or Internet data source, or a cloud service in another VPC, bind an EIP to the CDM cluster or use a NAT gateway to enable the CDM cluster to share the EIP with ECSs to access the Internet. For details, see Adding an SNAT Rule.
Constraints Subnet: No IP address in the subnet is being used by other resources, such as virtual IP addresses, elastic network interfaces, supplementary network interfaces, ECSs, SNAT rules of NAT gateways, VPC endpoints, VPC endpoint services, and load balancers.
If CDM needs to access a local or Internet data source, or a cloud service in another VPC, bind an EIP to the CDM cluster or use a NAT gateway to enable the CDM cluster to share the EIP with ECSs to access the Internet. For details, see Adding an SNAT Rule.
In the NAT environment, multiple terminals use the same public IP address, and one-to-one connection between the server and client cannot be implemented.

You can easily bind an EIP to an 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.
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.
ELB, NAT Gateway, VPC Endpoint and DCS are deployed in the VPC. Refer to solution 1 or solution 2. When method 2 is used, if a VPC wants to access public network, the traffic from the VPC is forwarded to the enterprise router and then to the public network.
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.
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.
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.

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.
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

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.
