In this guide I will show you how to connect your Windows (all versions) PC/laptop to any VPN service that’s using the L2TP/IPSec protocol. L2TP over IPSec is a relatively common and secure protocol and most VPN service providers and workplaces will support it.

Before we start the connection setup process, you will need to find out the following details (best have them written down or printed). If you are connecting to a paid VPN service, just login and your details and settings will be there. If you are connecting via a workplace, please contact your Network Administrator and ask them for the following details:

Required Info

• Your VPN username
• Your VPN password
• The server name or IP address (ie. contoso.com or 102.562.243.12)
• The pre-shared key (PSK)
  (PSK will be a series of characters like a password)
• Optional or required encryption
• The password protocol (PAP, CHAP, MSCHAP or EAP)

Once you have this info you can then watch the video above or follow the text guide below.
