cloud - 如何使用 nat 网关将 Internet 绑定流量从公共子网发送到私有子网

Question

我遵循了这些说明

    1. create nat gateway in public subnet
    2. configure a route table with destination 0.0.0.0/0 and Target as NAT gateway
    3. I tried to edit Edit subnet associations and attach private subnet 

在第 3 步，我收到错误，例如 There was an error to save subnet association for Private Route test Table 2。

还有另一个错误 The NAT gateway not associated with routing table

那么如何解决呢？知道我在做什么错吗？
