You can also restrict the route scope of internet gateway to use a smaller range instead of 0.0.0.0/0. i.e., on connecting through SSH to machine B from machine A, the machine B should automatically SSH and connect to the MySQL RDS instance (machine C). SSH is a standard for secure remote logins and file transfers over untrusted networks. The following example uses the MySQL Workbench client to connect to the bastion host: How do I resolve problems connecting to my Amazon RDS DB instance? mysql -h 127.0.0.1 -P 3307 --enable-cleartext-plugin --user=${IAMDBUSER} --password=${TOKEN}.
