How to build up a VPN Server on Your Windows OS Without Any third party Software...

Windows gives the inbuilt ability to function as VPN server, although this option is invisible. It's exploits on both Windows 7 & 8. The server uses the point-to-point tunneling protocol (PPTP.)

This could be helpful for connecting to your home network with public network, playing LAN games with someone, or securing your network on a open Wi-Fi connection – a hardly of the many reasons you might need to apply a VPN.

Boundaries:

While this is a exciting feature, it may not be the ideal path to grant VPN connections to your local network. It has several boundaries:

• You'll require the ability of forward ports from your router.
• You've to uncover Windows and a port for the PPTP VPN server straight to the Internet, which isn't idealistic from a protection point of view. You had better apply a strong password and consider utilise a port that Is not the default port.
• This Is not as simple to build up and use as software suchlike LogMeIn Hamachi and TeamViewer. Almost people will likely be better away with a additional complete software package similar those two.

Creating a VPN Server:

First gear, you have to goto the Network Connections windowpane. The smart direction to open it is to press the Windows key, type "ncpa.cpl", and hit Enter.

Now. Press the Alt key & click on the File menu that appears, and click on New Incoming Connection.

Now, select the user accounts that can connect remotely. To gain protection, you may prefer to create a fresh, restricted user account instead of allow VPN logins from your primary user account. (Click on Add someone to create a new user account). Check the user you allow has a very potent password, because a weak password could be cracked by a dictionary attack.

Do check mark on  the "Through the Internet" option to permit VPN connections over the Internet. You'll be also able to permit incoming connections over a dial-up modem, if you've a dial-up hardware.

and then pick out the networking protocols that should be enabled for incoming connections. E.g., if you don’t want that connected people have access to shared files and printers on your local network, you can uncheck the File and Printer Sharing option.

Now Click the Allow access button and Windows will set up a VPN server.

If you desire to disable the VPN server in future, you can delete the Incoming Connections item from your Network Connections windowpane.

Router Setup:

You'll now require to login @ your router’s setup page and forward port 1723 to the IP address of the computer where you set up the VPN server.

For supreme protection, you've to create a port forwarding rule that forwards random “external port” – such as 23243 – to “internal port” 1723 on your computer. This will allow you to join to the VPN server using port 23243, and will protect you from malicious programs which can scan and attempt to connect automatically to VPN servers working on the default port.

You can also consider firewall to only allow incoming connections from specific IP addresses.

Connecting to VPN Server:

Use the Connect to a network option in your Windows and enter your computer’s public IP address. Type the username and password you created to log in.

click Next and that's it.
