If not, the IP address may be unreachable due to firewall, NAT Gateway, or DNS configurations. For an HTTPS protocol, the endpoint must start with https:// and be a public IPv4 address, IPv6 address, or domain name.
If NAT 64 protection is enabled and IPv6 access is used, allow traffic from the 198.19.0.0/16 CIDR block to pass through. NAT64 will translate source IP addresses into the CIDR block 198.19.0.0/16 for ACL access control.
EIPs can be bound to or unbound from ECSs, BMSs, virtual IP addresses, NAT gateways, or load balancers. Various billing modes are provided to meet diversified service requirements. URI POST /v1/{project_id}/publicips Table 1 describes the parameters.
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.
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.
High performance requirements: Cloud Native 2.0 networks use 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
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.

You can also choose whether to clear resources used by the cluster, such as NAT gateways, security groups, and VPCEP resources.

The source and destination addresses must be private IP addresses. 2: NAT rule.

If a pod tries to access a private CIDR block, the source node will not perform NAT on the pod IP address.
Network planning Huawei Cloud designs public network access, including access via the NAT gateway, elastic IP address (EIP), and proxy servers.
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.
