Save the connection for future use, name it “Bastion-EC2”.

Destination: :5432 (assuming you are connecting to a Postgres DB listening on 5432, if SQL server this should be 1433).

Choose an open port on your local machine (ie.

Under SSH->Tunnels, you will now create a tunnel through the EC2 machine to the RDS machine:.

Select the PPK file as the private key for authentication.

Under Host Name, set IP Address: 127.0.0.1 and Port: to be the same port configured as the local port in the SSH tunnel from the previous step (in our example that would be 6000).

This connection itself will then setup another SSH tunnel that will run through the EC2 connection and map a local port on the Host to the RDS server endpoint and port. This second connection will sit on top of Putty Connection #2 and leverage the SSH tunnel setup within it to connect to the EC2 machine.

Leave this connection open while you move on to configure the next connection.Ĭreate Putty Connection #2 from the Host to the EC2 machine.

Click “Open” and you should be connected to the Bastion host machine, login with “ec2-user” (if the Bastion host is running Amazon Linux).

Save the connection so you can use it for future use, name it “Bastion-EC2”.

In the above, I have mapped the local port 6000 to the EC2 at 172.31.25.107 at remote port 22.

Destination port: Input :22 and click Add.

Source port: Choose a local port which is not being used on your machine, for example 6000.

Check the box marked “Allow Agent Forwarding”.

PPK file as the private key for authentication

Open Putty, under Host Name, put the public IP address of your Bastion host, and specify Port 22.

Steps to Creating SSH Tunnels with Putty Create Putty Connection #1 from the Host to the Bastion The Bastion serves a jump box that intercepts the forwarded data and then pushes it on to the downstream system. In our example, we will connect to the Bastion host over SSH and then through that Bastion host we will create a SSH tunnel from our local ports to the remote EC2/RDS machines. The SSH tunnel created by PuTTY will forward data sent to these local ports to the remote IP/port and then return back the response. To connect to EC2/RDS machines, you will use a concept called SSH tunneling.Īn SSH tunnel is a way to create a secure connection from a local computer to a remote one over a SSH connection done by mapping a local port on your machine to a remote IP address/port combination.

A Windows machine running the PuTTY client and the pgAdmin client.You will also need the RDS endpoint/user/password that you want to connect to (in our case we are using a PostgreSQL DB running on port 5432)

Not only will this article show you how to create a SSH terminal connection to an EC2 machine, but it will also show you how you can setup pgAdmin to connect and administer a RDS hosted PostgreSQL database without having to expose the RDS instance on a public subnet! Pre-requisites: In this post, I will quickly walk through the steps necessary to create the SSH tunnels necessary to access an EC2 machine and a RDS database sitting on internal subnets in AWS from a Windows terminal using the PuTTY tool (henceforth referred to simply as “Putty”). Accessing AWS resources, such as a Linux EC2 machine or a PostgreSQL database hosted on RDS, from your local development machine can be a little bit tricky, since these resources are generally recommended not to be exposed to the Internet and involves a technique called SSH tunneling.
