To connect to your rds you'll need to have a security group as well a VPC setup.  

  • Click on RDS > select Db > Connectivity and security
  • Click the VPC link
  • There is a section called IPv4 CIDR.  (This is what you need!)

Under EC2

  • Click Ec2 > select instance > Security Groups
  • Inbound > edit Custom TCP Rule > Port > Source = VPC Ipv4 CIDR
