Overview

Welcome to NAT Gateway API Reference. The NAT Gateway service provides the network address translation (NAT) function for Elastic Cloud Servers (ECSs) and Bare Metal Servers (BMSs) in a Virtual Private Cloud (VPC). It also supports this function for your on-premises servers that connect to a VPC through Direct Connect or Virtual Private Network (VPN). It allows these servers to access the Internet using elastic IP addresses (EIPs) or to provide services for the Internet.

This document describes how to use application programming interfaces (APIs) to perform operations on NAT gateways, such as creating or deleting NAT gateways, or adding SNAT rules. For details about all supported operations, see API Overview.

If you plan to access NAT gateways through an API, ensure that you are familiar with NAT gateway concepts. For details, see Service Overview.
