What Is NAT Gateway?

The NAT Gateway service provides the network address translation (NAT) function for servers, such as Elastic Cloud Servers (ECSs), Bare Metal Servers (BMSs), and Workspace desktops, in a Virtual Private Cloud (VPC) or servers that connect to a VPC through Direct Connect or Virtual Private Network (VPN) in local data centers, allowing these servers to access the Internet using elastic IP addresses (EIPs)

  • The SNAT function translates private IP addresses to a public IP address by binding EIPs to servers in a VPC, providing secure and efficient access to the Internet.
