Your article is really nice and thank you very much! But I am having problems using the PPTP.

(Im not good at English, if i make any mistake, Ignore it ^_^)

I follow the similar way to connection PPTP, but I don`t know the server's domain.

And when I start VPN, system let me enter the password to login sever (I had enter the password and account when i set the VPN), i can only enter them again, then I waited the feedback long time, at the last, system said: Remote server has disconnected the connection.-_-|||

I need VPN to through Internet blockade. Please help me, thank you!
