Use PuTTY to log in to the NAT server with an elastic IP address bound. Ensure that user root and the key file (.ppk file) are used for authentication. Then, use SSH to switch to the SAP HANA node that works as the active node.

This may include configurations of DNS, ELB, NAT, and Nginx.conf. Parse configuration files: For each configuration file, you need to compile scripts or use existing tools to parse the content.

Check Item 2: Network Connection Between the Cluster and UCS Public network access Check whether a public IP is bound to the cluster or a public NAT gateway is configured. Check whether the outbound traffic of the cluster security group is allowed.
Ensure that the HANA ECSs/ECSs where SAP HANA, SAP HANA Studio, and NAT servers are to be deployed use the same key. Otherwise, SAP HANA installation will fail.

NAT64 is an IPv6 conversion mechanism that enables communication between the IPv6 and IPv4 hosts using network address translation (NAT). WAF can convert an IPv4 source site to an IPv6 website and converts external IPv6 access traffic to internal IPv4 traffic.
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.
In containers, enabling this parameter can prevent the bandwidth of TCP connections that have been translated using NAT from being limited.

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.
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.
