Hi Isaias, thanks for you guidance.
I am aware of how dangerous is expose data in the Internet.
I have Internet access via a regular xDSL broadband modem in my house. It also have a built in router capability. I do not have firewall. I use Windows 8. Regular Internet user.
I believe VPN is for security matters. Not mandatory but I would considerer it in the future. Good to know that SAP Router configuration is not mandatory also.
My Internet public IP begins with 200* (Dynamic IP from my ISP) and my local network with 192.168* (Router/Modem). Any PC/Laptop can access my SAP ERP server inside my local network. it´s just add SAP Gui entries.
Could you please provide more details about NAT configuration for this requirement?
I would appreciate a step by step on that.
Thanks,
Flavio.
