Love Liu Yan How to create a NAT gateway

　　To create a NAT gateway

Describe

Creates a NAT gateway in the specified VPC.

Some notes:

Nat Gateways and "Self-built Snat gateways" (using an ECS as Snat Gateway) are not currently supported in VPC, and if so, undefined product behavior is generated (this usage will be supported in future product iterations)

When the Nat gateway is created, a "0.0.0.0->natgateway_id" system route appears in the routing table to ensure that messages that need to be forwarded by the Nat gateway to the public network can be forwarded by the router to the NAT network.

Natgateway creation failed when a custom route "0.0.0.0/0-> an ECS" already exists in the routing table;

Request parameters

name	type	whether you must	Description
Action	String	Is	System specified parameters, values: Creaenatgateway
RegionID	String	Is	The region where the Natgateway was created
Vpcid	String	Is	In which VPC to create the Natgateway
Bandwidthpackage.n.ipcount	Integer	Specify at least one	Number of public network IP in nth bandwidth packet (n is currently only 1) Value range: 1-50
Bandwidthpackage.n.bandwidth	Integer	Specify at least one	Bandwidth value of nth bandwidth packet (n is currently only 1) Value range: 5-5000
Bandwidthpackage.n.zone	String	Whether	The available area of the nth bandwidth packet (n is currently only 1) When this parameter is not specified, the system randomly selects the available extents for allocation. n the IP on the shared bandwidth packet is not in the same usable area as the back-end ECS, it does not affect its connectivity, but it can achieve a more extreme latancy performance when it is located in a total usable area.
Name	String	Whether	The display name of the instance, [2, 128] English or Chinese characters, must begin with a size letter or a Mandarin, can contain numbers, ".", "_" or "-". The instance name is displayed in the console. N If this argument is not specified, the INSTANCEIDN with the default value instance cannot begin with http://and https://.
Description	String	Whether	Custom description [[2, 256] characters, the instance description is displayed in the console. Blank if not filled, default is empty. Can't start with http://and https://.
Clienttoken	String	Whether	Used to guarantee the power of the request. This parameter value is generated by the client to ensure that it is unique between requests and that the maximum is not worth 64 ASCII characters. See Appendix for details

return parameters

name	type	Description
Natgatewayid	String	Natgateway instance ID, generated by the system, globally unique. Is the unique identification of the access instance
Forwardtableids	Array	List of IDs for Port forwarding publications
Bandwidthpackageids	Array	ID List of bandwidth packages created together

Error code

Error code	Description	Http Status Code	Semantics
Invalidregionid.notfound	Specified value of "RegionID" is not supported.	404	The specified Region does not exist
Invalidzoneid.notfound	Specified value of ZoneID is not supported.	404	The specified ZoneID does not exist
Invalidvpcid.notfound	Specified value of ZoneID isn't found in our record.	404	The specified VPC does not exist
Missingparameter.bandwidthpackage	At least 1 Bandwidthpackage must is created with Natgateway.	400	At least one shared bandwidth package needs to be created with NATGW
Missingparameter.bandwidthpackage.n.ipcount	Missing parameter Ipcount in bandwidth N.	400	Nth Bandwidth packet parameter incomplete, unspecified Ipcount
Missingparameter.bandwidthpackage.n.bandwidth (n need to give a specific value)	Missing parameter Bandwidth in bandwidthpackage N. (n need to give a specific value)	400	Nth Bandwidth packet parameter incomplete, unspecified Ipcount
quotaexceeded.natgatewaycountinonevpc	Natgateway count limit in one VPC exceeded.	400	There is only one natgateway in a VPC.
routerentryconflict.duplicated	A Route entry already exists, which CIDR is ' 0.0.0.0/0 '	400	Cannot add natgateway when a custom route with ' 0.0.0.0/0 ' exists in the routing table
