CreateNatGateway

GET /?Action=CreateNatGateway
Description

Creates a network address translation (NAT) gateway in the specified public subnet of a VPC.
A NAT gateway enables instances placed in private subnet of this VPC to connect to the Internet, without being accessible from the Internet.
When creating a NAT gateway, you specify the allocation ID of the External IP address (EIP) you want to use as public IP address for the NAT gateway. Once the NAT gateway is created, you need to create a route in the route table of the private subnet, with 0.0.0.0/0 as destination and the ID of the NAT gateway as target. For more information, see AssociateAddress and CreateRoute.
This action also enables you to create multiple NAT gateways in the same VPC (one per public subnet).

Note

You cannot modify the EIP associated with a NAT gateway after its creation. To do so, you need to delete the NAT gateway and create a new one with another EIP.
