S4HANA SAP CAL using AWS

Dear Folks,

I have installed a S4 HANA box using SAP CAL on AWS and I have an issue that when I connect using the AWS Windows Server I can access everything including FIORI launch pad and SAP GUI.

But when I go outside AWS Windows RDP Account I am not unable to access anything either FIORI launchpad or SAP GUI for the system.

What I think is that do I need to set up a Virtual Private Gateway for the Instance with a VPC that is already working or do I need to do something else.

Please help in this as this is kind of urgent.

Regards.
