how to remote access mysql db on ec2 hub?

I'm having a bit of trubble accessing my sql remotely on my new ec2 instance. I want to syncronize a database and I can't seem to connect to it. If anyone out there could tell me what I'm missing I'd sure appreciate the help.

1 . I made a new database user=  no certificate, all permissions, hosts any

2. New firewall rule: Accept If protocol is TCP and destination port is 3306

Normaly i would expect that to work? What am I missing?

thanks!
