HOW TO MANUALLY CONFIGURE YOUR FREE VPN- VIRTUAL PRIVATE NETWORK WITH TEAMVIEWER

This tutorial is from SMART PC TRICKS,  and is wonderfully detailed, so i thought i might share it here

What is VPN? A virtual private network (VPN) is a network that uses Internet, to allow remote offices or individual users with secure access to their organization’s network just like in local area network. How to create free software VPN? Let’s start building free VPN.! The security achieved by tunneling like Layer Two Tunneling Protocol (L2TP). In VPN connections the sender encrypting data and receiver decrypting it at the receiving end thus creating a Tunnel.
Usually CISCO VPN routers are used for corporate VPN setup. We will discuss more about VPN and VPN configuration in detail on later articles.
Is it possible to create VPN without dedicated hardware like CISCO VPN router and leased line? Yes, with the help of VPN client softwares we can configure Virtual Private Network. In this article we will cover How to set up and configure free VPN using Team Viewer, they are providing VPN service.

How VPN Protects from Hackers?

By encrypting the data VPN acts as a Virtual Tunnel between sender and receiver. Only the receiver can decrypt data. A Hacker can access the encrypted data thus unable to detect original data.
For example consider

• I’m encrypting the word ‘SmartPCTricks’ using some digital algorithms and converting it in to another data like ‘*!&@^#%$’.

• Sending the encrypted data packet over internet. Only the receiver can decrypt ‘*!&@^#%$’ to actual data ‘SmartPCTricks’.

• If a Hacker try to access my network he may getting only ‘*!&@^#%$’. The encrypted data path is termed as Tunnel! 

How TeamViewer VPN Works?

We have already discussed with Team Viewer, the best Remote Desktop Software. But most of the peoples are unaware about the VPN client facility in Team Viewer.

We can create Virtual Private network via TeamViewer without any hardware (CISCO or other VPN routers).
The principle of TeamViewer Tunneling is same as normal VPN but the only difference is that the encrypting and decrypting is done in the computer itself. No hardware required for encryption and decryption. Encrypting carried by a Virtual Network Adapter and Team Viewer software.

• Computer Name\User Name (If remote PC not under a Domain) 

For example my Office computer not in the domain,
Computer Name: User-PC
My user name: User
So I provided User-PC\User.

NB: You must have a password protected user account on the remote PC
Yes, That’s it. Now we have done free VPN, you are able to access the remote PC just like in a local network. You can access file, Shared folders and Shared printers etc.
