Enter all the fields as described above in the PPTP setup. You will just see one added feature i.e. You will have to enter a Secret. The secret will also be provided to you by your VPN Service Provider. That will be unique to a VPN Service Provider for providing L2TP Connection.

Its for you to connect to a VPN Server.

  • Will a VPN on a Iphone allow you to go on facebook on China? The VPN i use is this www.freecanadavpn.com. It sets up and works and has the VPN sign on the top. But if i travelled to china would it allow me to go on Facebook, youtube… On the iphone connecting to a local Wi-Fi network? When i connect it doesn't tell me to like select a different location or IP address. So i'm not sure if this just works as a hotspot shield or if it actually allows you to go on facebook in china.
