Don't know if you still need this today. AWS offers port forwarding and some other stuff, with EC2 instances, for free now. I haven't used this method of locking down SSH in a very long time.

Not sure how much that relates to my situation here, but I wanted to change the SSH port which I initially use to connect to the EC2 instance.

Otherwise when I see the sshd logs, I see many people/bots lurking in. Just too many attempts to get in.
