多应用如何共享NAT 网关的公网带宽？

步骤一：创建NAT网关 调用CreateNatGateway接口创建NAT网关。

[admin@tester:xxx]$ python api.py CreateNatGateway RegionId=cn-shanghai VpcId=vpc-11af8l**** BandwidthPackage.1.IpCount=4 BandwidthPackage.1.Bandwidth=150 BandwidthPackage.1.Zone=cn-shanghai-a Name=MyNatGW Description="My first NAT Gateway" =====Request URL====== https://ecs.aliyuncs.com/?SignatureVersion=1.0&VpcId=vpc-11af8l****&Name=MyNatGW&Format=json&TimeStamp=2016-05-23T03%3A26%3A21Z&BandwidthPackage.1.IpCount=5&RegionId=cn-shanghai&AccessKeyId=jZgi0oyrQXXXXXXX&SignatureMethod=HMAC-SHA1&Version=2014-05-26&Signature=I4KKhWgjJdImTqk4rCifAB3LbLw%3D&action=CreateNatGateway&SignatureNonce=1ebae49c-2096-11e6-b781-2cf0ee28adf2&BandwidthPackage.1.Bandwidth=150&BandwidthPackage.1.Zone=cn-shanghai-a&Description=My+first+NAT+Gateway =====Request URL end====== ====== Got Response ====== { "BandwidthPackageIds": { "BandwidthPackageId": [ "bwp-11odxu2k7" ] }, "ForwardTableIds": { "ForwardTableId": [ "ftb-11tc6xgmv" ] }, "NatGatewayId": "ngw-112za33e4****", "RequestId": "2315DEB7-5E92-423A-91F7-4C1EC9AD97C3" 调用DescribeNatGateways接口查看NAT网关的详细信息。
