配置公网NAT网关使SAE应用能访问公网

SAE应用实例不具有公网IP，无法直接访问公网上的资源或服务。在SAE应用所在的VPC创建公网NAT网关，即可为所有SAE应用实例主动访问公网提供代理服务。

引言：上一篇提到双ISP使用双链路接入时，本地网关需要使用SLA、Track和Route-map等手段实现链路切换时NAT转换的切换。但有些时候，某些供应商只通过一条链路（如图中R1到SW4），提供接入到两个更高级运行商的服务（如电信、联通等）。这个时候，在R1只有一个逻辑出口的情况下（即不考虑trunk等多逻辑接口的方式）时，之前的route-map将无法以出接口作为NAT转换的判断条件。本....
