Windows Built-In VPN (Windows, Free)

Windows has a built-in VPN client. Surprised? Many people are. It's not a heavily advertised feature, but it covers many people's needs. Before exploring other client solutions, it's worth pulling up the quick launch box in the Windows start menu and typing "VPN" to start the configuration process. In Windows versions prior to Windows Vista, the built-in VPN client received a fair amount of criticism for lacking features and supported protocols. Since Vista and especially in the Windows 7 implementation, it's grown significantly and unless you need a feature or standard that isn't implemented you may not need to install anything at all.

En otros tutoriales se explica cómo configurar la red en GNU/Linux (Ubuntu 11.10) y Mac OSX... Y con este  para windows 7 ya tendríamos una red VPN PPTP en los principales sistemas.

Procedimiento Pulsar sobre el icono de nuestra red, en este caso de cable, y a continuación sobre“Abrir centro de redes y recursos compartidos“.

En la ventana que se ha abierto, presionamos sobre “Configurar una nueva conexión o red“.

VPN: Asistente

Una vez iniciado el asistente de configuración nos dará la opción de elegir entre diversos tipos de conexión, en nuestro caso tendremos que seleccionar “Conectarse a un área de trabajo“.

A continuación tendremos que elegir el modo de conexión, es decir, si queremos que establezca una conexión directamente con el servidor de la VPN o si por el contrario queremos que use la conexión activa, de modo que seleccionamos “Usar mi conexión a Internet (VPN)“.

En este punto tenemos que establecer los parámetros de la red, empezando por la dirección del servidor y un nombre que nos permita diferenciar la conexión VPN que estamos configurando del resto de conexiones existentes. El resto de opciones las dejamos sin marcar.

Por último nos pide que insertemos nuestro nombre de usuario y contraseña de la VPN, en caso de conectarnos a una red con dominio, normalmente en entornos empresariales, tendrías que escribirlo también, no es nuestro caso así que lo dejamos en blanco.

A continuación el asistente conectará con la VPN para verificar que todo está correctamenteconfigurado.

VPN: Conectar y Desconectar

Por último, para saber que estamos conectados a la VPN o bien para desconectarnos de la misma, tan sólo tendremos que pulsar de nuevo sobre el icono de la red para que aparezca la conexión. Para desconectarnos sólo tendremos que pulsar sobre la misma y a continuación sobre el botón “Desconectar“.

How to Set Up PPTP VPN Server in Windows 7

How To Set Up A VPN Server On Windows 7 by Aatif Khan

Virtual Private Networks (VPN) are an important tool in remote connectivity, especially in corporations and professional organizations, but their usage may vary from instance to instance. In any case, VPNs allow a user to access a remote network’s resources with ease, and has the potential to make life a lot easier for the end user should it be used properly.

With Windows 7, setting up a VPN server on your PC that can be accessed from anywhere on the internet is pretty simple, yet most people are neither aware of the benefits nor know the process. In this article, I’ll guide you throughhow to set up a VPN server on Windows 7 without using any extra software or applications.

Assumptions

Before I go into detail on how to set up a VPN server, here are a few assumptions that this guide makes:

• Your internet connection utilizes a router, on which you have port forwarding permissions
• You know your way around your router’s user interface setup, because they vary with make and model
• You understand and acknowledge any potential security risks involved with using VPNs
• Administrator access on the machine where you’re trying to setup the VPN server

How to set up a VPN server

The process is not that complicated. Let’s begin.

Navigate to Windows Control Panel, and select Network and Internet. You then need to access the Network and Sharing Center, bringing you to a screen showing all your network information and configured connections. On this window, select ‘Change adapter settings’ from the left sidebar.

Clicking this will bring you to a new window listing all your network connections, however many you may have. In this window, the top menu bar is usually hidden (as with all of Windows 7), so press Alt to bring it forth, and navigate toFile > New Incoming Connection.

A wizard shall now start which will help you set up a VPN server on your PC. In the first screen, you define who shall be able to access your network – it can be anyone from you to your spouse or children – but it’s generally a good idea to give your administrator account access to connect via VPN as well.

Hit Next and you will be telling your computer how people will connect to the VPN. Usually there is only one option available, “Through the internet” but in my case you can see an additional one which is a virtual modem.

The final page will determine what kinds of machines can access the VPN – including Macs and Unix servers – so it’s best to leave the default setting as it is here.

Complete the wizard, let it populate the VPN settings and wait till you’ve given with a final name for this incoming connection. This name would usually resemble your PC’s network name, but make a note of it as this information will be required to establish connectivity with the VPN.

Connecting to your VPN

Next, you need your PC’s IP address and the default gateway. If that information is not already available, the easiest way to obtain it is using “ipconfig” command in Windows’ command prompt interface. See the screenshot below.

Finally, you need to add VPN’s communication port to your router’s settings. To do that, log in to your router and navigate to port forwarding settings (there are no standard instructions because every router’s interface varies from others). You need to create a new forwarding to port 1723 which is by default the port that VPNs use to connect. Also, this port needs to be pointed to your PC’s IP address that was obtained through ipconfig command. Save your settings and reboot the router once.

That completes the entire tutorial on how to set up a VPN server on your Windows 7 computer. Depending on your machine and hardware, you may require a couple of reboots more both on your PC and router, but that’s about it. Your VPN server is up and ready for any client computer to communicate with.
