VPN SERVER MAC UPGRADE
On a side note, provided that windows 10 works, my plan is to upgrade to the pro version but I don't want to spend the money if I'm just going to roll back to windows 7 because VPN doesn't work. There must be something that changed between the way that windows 10 and windows 7 handles vpn security.īefore someone says this is a Mac problem, it worked flawlessly for months with windows 7 and broke immediately after the upgrade. I've checked all of the registry changes that I had originally made in windows 7 and they are all still intact. Because I have the home premium version of windows I don't have access to secpol.msc but I was able to make the necessary changes directly in the registry and get The VPN connection to work great in windows 7.Īfter upgrading to windows 10, the vpn connection no longer works.
