In essence, this will cause your SSH client to listen for connections on a configured port, and forward connections received on that port to an SSH server (what you have referred to as the proxy). In order to establish a connection to your RDS database from within your organization's network, you'll need to configure SSH port forwarding on your local machine. You only need to create an SSH tunnel for development/testing purposes. You are working in a development environment that requires access to an RDS database ![]() The "proxy" you are referring to between your machine and the AWS RDS instance is a EC2 gateway server Ī local, development instance of the database does not exist within your organization The following instructions assume a particular use case:
