本篇文章教大家NAT网关如何配置，NAT网关配置相当于路由器，如果服务器ECS没有公网IP只有私网IP，也可以依靠NAT去上网。话不多说，直接开始！
购买NAT网关并配置弹性公网IP
立即购买，确认订单，签署并下单，资源创建完毕后进入控制台。
配置DNAT管理
配置好后，我们可以通过xshell连通，但是依旧无法上网
[c:\~]$ ssh 8.130.74.161 6666 Connecting to 8.130.74.161:6666... Connection established. To escape to local shell, press Ctrl+Alt+].

SNAT配置
创建好后，web1和web2皆可联网
