• Edit your /etc/ssh_config file locally on your Mac and add these lines:

Host any_name_for_this_connection
        User ec2-user
        HostKeyAlias any_name_for_this_connection.www.website.com ( can be anything )
        HostName 54.164.25.211 ( host of NAT or server that you can SSH into )
        LocalForward 1025 10.0.1.43:22 ( local port to enable connection through | internal AWS IP of private server )
        IdentityFile ~/.aws/private_key.pem

Host another_connection_name
        User ec2-user
        HostKeyAlias another_connection_name.ec2.internal
        HostName localhost
        Port 1025
        IdentityFile ~/.aws/private_key.pem

• when connecting via terminal:
  1. Create the connection on port 1025 through the server you can SSH into: ssh -C any_name_for_this_connection
  2. Connect to the private server: ssh another_connection_name
• When connecting via a text editor like Coda or TextWrangler
  1. Create the connection on port 1025 as above.
  2. Then set the host in your text editor to localhost on port 1025.
