How to Whitelist Amazon EC2 security groups on Mongolab

Question

I am trying to Whitelist Amazon EC2 security groups (AWS only) and followed this link http://docs.mongolab.com/security/

I am getting this error "You may not define rules between a VPC group and a non-VPC group".

I searched on the internet about this and found this is an issue of EC2-Classic vs EC2-VPC. If you created your account after 2013-12-04, it supports EC2-VPC only.

So how can I add security group of amazon here. And my security group is also in us-east-1

Answer 1

That feature was only for the old "EC2 Classic" version of AWS. Now that Amazon requires everybody to use a VPC, the MongoLab security group feature doesn't work.
