Introduction
NAT Gateway is a fully managed network address translation (NAT) service from Alibaba Cloud that enables resources within a Virtual Private Cloud (VPC) to securely access the Internet. By translating private IP addresses to public IP addresses, NAT Gateway provides controlled outbound connectivity while preventing direct exposure of internal resources to the Internet.
Setup
To set up the Alibaba integration and discover the Alibaba service, navigate to Alibaba Integration Discovery Profile and select NAT Gateway.
