There's a professional software package installed on a standalone (non-MS exchange) Windows 7,8 desktop. I want to use my Mac notebook to network to that desktop in order to access the professional software package. The software package is used via a browser, so I assume that once I achieve the network connection, I can used the Mac's browser to operate the software that's on the Windows computer. The network connection has to be via internet, to let me access the software even from overseas via internet. It was told the Mac can network to the Windows desktop computer by opening the firewall for HTTP/port 80. I'm unfamiliar with connecting a Mac to a Windows computer for this purpose. Can someone either tell me how, or point me to whether I can get information on how to get this done? The software resides on the Windows 7/8 desktop computer, and I want to connect the Mac (via internet) to the Windows computer to make use of the software. (That's permitted under the software package's licence).
