Overview
You can use a private NAT gateway to enable communications between cloud and on-premises networks.
The following figure shows how a private NAT gateway enables ECSs in a VPC to communicate with your on-premises data center that has been connected to the cloud using Direct Connect.
Figure 1 Networking diagram
In this example, the CIDR block of your on-premises data center is 10.0.0.0/24. The subnet of the transit VPC in the region is 10.1.0.0/24.
How networks are connected to each other
- Your on-premises data center is connected to the transit VPC using Direct Connect.
- The VPC where your services are deployed is connected to the transit VPC using a private NAT gateway.
This following figure shows the procedure.
