How to access BSP externally

Hi Experts,

I'm new working with BSP, I've developed a BSP application that is already working on my browser, I've configured the parameter 'host_name_full' withing the system using the transaction RZ10 and I've modified the file 'hosts' in C:WINDOWSsystem32driversetc. The application can be viewed within the LAN of the enterprise; I would like to know: How can I access this application from outside my VLAN, like a normal Internet URL?

Thanks for your help,
