Can I specify which subnet will use which gateway as its default?
是否可指定哪個子網路將用哪個閘道作為其預設閘道？
Yes. You may create a default route for each subnet. The default route can direct traffic to egress the VPC via the Internet gateway, the virtual private gateway, or the NAT gateway.
是。您可以為每個子網路建立預設路由。預設路由可以引導流量透過網際網路閘道、虛擬私有閘道或 NAT 閘道從 VPC 傳出。
