SSH forward local port to remote AWS RDS instance

The scenario:

We have connectivity to remote server (EC2 instance) REMOTE_EC2_HOST over SSH.
Connectivity to AWS RDS MySQL instance RDS.ENDPOINT.rds.amazonaws.com from remote server only (due to security group/firewall settings).

# forward requests from 127.0.0.1:6400 -> RDS.ENDPOINT.rds.amazonaws.com:3306
# add [-f] switch to background ssh process
$ ssh -vvvN \
	-L 6400:RDS.ENDPOINT.rds.amazonaws.com:3306 \
	-i /path/to/rsa/private/key \
	USERNAME@REMOTE_EC2_HOST

# connect to MySQL on 127.0.0.1:6400
$ mysql --host 127.0.0.1 --port 6400 --user MYSQL.USER --password
