步骤2：购买弹性公网IP 操作场景 通过购买弹性公网IP来实现云专线接入公有云的用户，以NAT网关的形式共享弹性公网IP访问公网或为公网提供服务。 操作步骤 详细步骤请参考申请弹性公网IP。 这里购买弹性公网IP后，无需绑定云主机。 父主题： 云间NAT网关高速访问互联网
recommended that the AK and SK be stored in ciphertext in configuration files or environment variables and decrypted during use to ensure security
为什么使用SNAT？ 对公网NAT网关来说，一些弹性云服务器不仅需要使用系统提供的服务，还需要访问外网以获取信息或下载软件。但是，给弹性云服务器分配公网IP需要消耗稀缺资源（如IPv4地址），增加额外的成本，并有可能增加虚拟环境遭受攻击的几率。因此，多个弹性云服务器共享同一公网IP是一种可行的
主机通过公网NAT网关访问外网，请问公网NAT网关的带宽是多少？在哪里设置？ 公网NAT网关的SNAT功能通过绑定弹性公网IP，实现云主机私有IP到公网IP的转换。云主机通过公网NAT网关访问外网时，其带宽大小和您购买弹性公网IP时选择的带宽大小有关。 带宽大小调整操作请参考修改带宽大小。 父主题： SNAT规则
