I am hosting a VPN server on my windows computer. However when I try to connect to it, I cannot figure out what the "Shared Secret Key" that it wants is and where I can find it. I have tried searching for this in countless places. Please tell me where I can find it and where I can create it. Thanks!
Windows version: Windows 8.1 Pro (going to update to Windows 10 Pro soon)
Here are all I get to see in the "Properties":
I am connection to the VPN on my Mac (OS X El Capitan 10.11.3 Beta) The wireless router I am using is the Apple Airport Extreme. I also port forwarded the necessary ports for an outgoing VPN connection.
