nat gateways

Network Address Translation (NAT) plays a crucial role in managing network resources, particularly in the cloud where resources must often be maintained and manipulated dynamically. NAT gateways allow for this flexibility, enabling private subnet instances to connect to the internet or other services while preventing unwanted direct connections from the outside. This step-by-step guide will focus on how to configure cloud NAT gateways using Bash, one of the most widespread and powerful scripting languages available on Linux systems. Whether you are setting up your NAT configurations on Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure, automation through Bash scripting can significantly streamline the process.
