EC2 Networking Setup - Servers Cannot Communicate

Question

I have Googled and looked through forums to understand what I need to setup so my servers can communicate with each other, however I am unable to get anything to work.  If someone could look at these servers and tell me what I'm doing wrong that would be great.  
  
I am trying to communicate over TCP via port 27017, I've setup the security group inbound/outbound rules allowing only the servers in the SG as the source.  
  
Instance IDs:  
  
i-032868188227d40a5  
i-034df5e7a520aac87  
i-0872e200d58c83978

Answer

Figured out what the issue was.  
  
When configuring your servers to talk to each other over a specific port, you must also setup the firewall on each server.  You should add an inbound/outbound rule to each server specifying the port you would like to communicate over.  I also added the remote IP of each server respectively while creating the firewall rules.

Answer

Is it possible to get some support on this?
