In containers, enabling this parameter can prevent the bandwidth of TCP connections that have been translated using NAT from being limited.
Figure 1 Specifying the number of allocatable container IP addresses on a node in the VPC network model By default, a node occupies three container IP addresses (network address, gateway address, and broadcast address).

Configure gateway timeout. Make sure that the persistent connection timeout period of backend services is greater than or equal to the connection timeout period of NGINX Ingress Controller. Configure HPA for NGINX Ingress Controller.
For example, a gateway container needs to access all other containers in the same cluster. 2. All available IP addresses in a container CIDR block are used up.
High performance requirements: Cloud Native Network 2.0 uses VPC networks to construct container networks, eliminating the need for tunnel encapsulation or NAT when containers communicate.
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

Default Advanced Settings Gateway Specifies the gateway address of the subnet. This IP address is used to communicate with other subnets. 192.168.0.1 DNS Server Address By default, two DNS server addresses are configured. You can change them if necessary.
Because container tunnel encapsulation and NAT are not required, Cloud Native Network 2.0 enables higher network performance than the container tunnel network model and VPC network model.
Deployment dashboard-kong Open-source API gateway component on which Dashboard depends, which helps manage APIs and implement authentication and authorization.
Time series data can be pushed to the Prometheus server in push gateway mode. Users can obtain the monitored targets through service discovery or static configuration. Multiple visual GUIs are available.
Changing the value of the kernel parameter net.ipv4.tcp_tw_recycle to 1 The NAT service becomes abnormal. Change the value to 0. Changing the value of the kernel parameter net.ipv4.tcp_tw_reuse to 1 The network becomes abnormal. Change the value to 0.
DNAT gateway Service Public network Same node as the service pod The access failed. The access failed. The access failed. The access failed. Different nodes from the service pod The access failed. The access failed. The access failed. The access failed.
For details, see NAT Gateway Price Calculator. In the use case described in this section, a NodePort Service is required to access the Kubeflow web UI. Ensure an EIP is bound to any node in the cluster. The EIP will be billed. For details, see Elastic IP Price Calculator.
CCE can work with NAT Gateway. Certain bugs are fixed. 2018-05-06 Changes: Namespace deletion. Users can specify an ELB port for health checks. Certain bugs are fixed. 2018-04-04 Changes: Cluster nodes support CentOS 7.1.
Check the result. kubectl get svc -n istio-system | grep istiod Information similar to the following is displayed: istiod ClusterIP 10.247.51.34 <none> 15010/TCP,15012/TCP,443/TCP,15014/TCP 4h8m Install the Kubernetes Gateway API CRD. kubectl get crd gateways.gateway.networking.k8s.io
DNAT A DNAT gateway translates addresses for cluster nodes and allows multiple cluster nodes to share an EIP. DNAT Services provide higher reliability than EIP-based NodePort Services.
After a request is forwarded to the backend server, if the backend server does not respond during the timeout duration, the load balancer will stop waiting and return HTTP 504 Gateway Timeout. This function is available only for HTTP and HTTPS listeners.
Components Table 2 AI Inference Framework components Component Description Resource Type frontend Provides a unified API gateway for forwarding user requests.
