I am trying to setup a VPN connection on Windows Server 2008 R2, there is nothing special about the configuration since this is just a test VPN and it is the same steps I used to do it a few weeks ago. I just want to setup a VPN -PPTP to test connect to my home from outside.
However, today I was hit with the error, please see the screenshot. I have been trying troubleshoot but I am totally having no clue now.
The error in the screenshot is from I tried to create a VPN connection from a windows 7 machine in the same network. I also tried on Mac but no luck.
But in the last minutes I tried to create a VPN connection on its own machine(windows 2008R2 which I have installed VPN) and it works(connected), but what is the point since I can't connect from outside. Therefore, please help me out. Thank you very much in advance.
