Standard NAT gateways of Alibaba Cloud are phased out.
Starting November 20, 2020, Alibaba Cloud stops offering standard NAT gateways in all regions. We apologize for any inconvenience that may be caused.
Create an enhanced NAT gateway
Enhanced NAT gateways are an upgrade from standard NAT gateways and use a more advanced architecture. Compared with standard NAT gateways, enhanced NAT gateways provide higher performance and higher elasticity. Enhanced NAT gateways support flexible billing methods and fine-grained maintenance. For more information, see Enhanced NAT gateways (new).
- When you create an enhanced NAT gateway in the console, you must specify a vSwitch for the NAT gateway. For more information, see Create NAT gateways.
- When you call API operations to create an enhanced NAT gateway, you must set the NatType parameter to Enhanced and set the VSwitchId parameter. For more information, see CreateNatGateway.
