Setting up the Android side:
I was giving a try to this tutorial: https://www.blacklogic.com/setup/androidvpn.pdf
But on step 13 you're asked for username & password, which I never saw where we were supposed to define them. I imagine this is to be defined during the Win7 setup, except that I don't have that tutorial
I also found this other tutorial for a Nexus One:
How to configure a VPN connection on your Google Nexus One - Know Your Mobile
But towards the end, the author just says: "Fill in VPN details such as VPN name, VPN server, etc (the required settings will depend on type of VPN selected)"
... "THE REQUIRED SETTINGS!" That's exactly why I'm making this post now!
As for setting up the Win7 side, I found this tutorial:
But then on step 7. it says: "Enter the username and password your VPN provider gave you in the appropriate boxes"... I guess is like in the previous tutorial made by BlackLogic, because is for their clients maybe.
I also found this other one, very different: How to: Windows 7 incoming VPN from Android Damian's Blog
But there's nowhere any username and password is setup.
Can anyone help please?
