I am trying to connect to SAP GUI in Eclipse but I am getting a timeout during allocate message. I think it has something to do with the connection. I am running the SAP GUI using AWS EC2 instance. When I set my security group to all traffic - 0.0.0.0/0 in AWS, I was able to connect, but we are not allowed to because it will be flagged. How will I know which specific IP do I need to add in my security group? Thanks and apologies if my question is confusing.
