Connect to Elasticache from outside with NAT instance

Question

I'm trying to configure AWS Elasticache access from the outside a VPC via a NAT Instance. The process is quite well documented here however every docs point to setup a rule in the iptables to forward the traffic to the IP address of Elasticache. The problem raises here because I don't have any IP address but just a DNS name. Am I missing anything?

Answer 1

我通过ping主要端点找到了专用IP地址

Answer 2

大多数AWS托管服务端点（如RDS，ALB，NLB，AD ...）将具有DNS名称，可以通过在VPC（内部端点）内执行nslookup来为其找到IP。
