Notes and Constraints If Network Address Translation (NAT) is used, you cannot obtain the IP addresses of the clients. If the client is a container, you can obtain only the IP address of the node where the container is located, but cannot obtain the IP address of the container.
Network resource cost Costs for network services such as Internet bandwidth, public IP addresses, NAT gateways, load balancers, and VPNs Database cost Costs for services such as relational databases and NoSQL databases.
Video Tutorial on Traffic Distribution Techniques This video shows how ELB uses network address translation (NAT) to distribute traffic.
You can also choose whether to clear resources used by the cluster, such as NAT gateways, security groups, and VPCEP resources.
versions later than Kubernetes 1.25, Kubelet uses IPTablesCleanup to migrate the Kubernetes-generated iptables chains used by the components outside of Kubernetes in phases so that iptables chains such as KUBE-MARK-DROP, KUBE-MARK-MASQ, and KUBE-POSTROUTING will not be created in the NAT

Egress visualization Data egresses: All data egresses on the cloud and on-premises are identified, including EIP, NAT, API Gateway, and ROMA.

If the cluster forwarding mode is iptables, run the iptables -t nat -L command to view the port. If the cluster forwarding mode is IPVS, run the ipvsadm -Ln command to view the port.

If a pod tries to access a private CIDR block, the source node will not perform NAT on the pod IP address.
Table 10 ForwardingInfo Parameter Type Description eip String Parameter description: EIP bound to the NAT gateway. enable_snat Boolean Parameter description: whether to enable the SNAT configuration. Options: true false Example Requests Querying an instance.

Because container tunnel encapsulation and NAT are not required, Cloud Native Network 2.0 delivers higher network performance than the container tunnel and VPC networks.
