I have a RDS instance (mysql) inside a VPC called vpc-a (10.0.0.0/16). This instance is private, it can only be accessed from vpc-a.
We created a stack on opsworks inside another VPC called vpc-b (10.1.0.0). We want to connect opsworks to the RDS but it doesn't work. It refuses to connect. I tried adding said subnet to the RDS security group. Also read a lot of documentation but I haven't stumbled across the answer. Any help would be greatly appreciated.
