Setting up VPN on Windows 7 (SEVEN)
Setting up a VPN account on computers using Windows 7 is a fairly simple task. Below you will find the Windows 7 PPTP VPN setup guide followed by the Windows 7 L2TP IPSEC configuration and finally the SSTP VPN guide. When you have created the Win Seven PPTP VPN connection you can either recreate it and do some more steps to make it L2TP or SSTP or you can simply open the VPN connection properties and make small changes to switch the VPN protocol used. In most cases PPTP will work great but when you travel to countries such as China, Iran, Oman, UAE, Qatar, Saudi Arabia or even are at some US hotel you may have an issue. If you are unable to connect with one protocol due to network restrictions, try the other 2 and you should be able to connect!
It is very important to note that when creating the VPN, please do not leave it set on "Automatic." You will have to specify PPTP or L2TP IPsec or SSTP (Secure Socket Tunneling Protocol) in the VPN connection properties.
