I'm in trouble on setting up a MySQL RDS.

From my EC2 instance, I can connect fine, but from my laptop, I get an error 2003 (timeout).

  • My RDS instance is configured to be publicly accessible.
  • My security group has rule inbound and outbound to allow all traffic everywhere (

Should I configure something on my VPC or Internet Gateway?

As your database is publicly accessible, the firewall would be the problem here. So, check your LAN's firewall settings. Also, let me give you documentation and a forum link which I think would be useful.
