Can a VPN Allow You to Circumvent Regional Restrictions?

Are you having trouble accessing a website based in another state or country? Many organizations use regional restrictions, such IP-based geolocation, to prevent internet users from other states and countries from accessing all or certain parts of their website. Your own organization may have implemented such as restriction, making it impossible for you to access your own website when you are away in a foreign country. If this is the case, then VPN may be the answer you are looking for.

But first, let’s find out what IP-based geolocation means. Every device connected to a computer network, including the internet, is automatically assigned a unique address consisting of a string of numbers punctuated by full stops. This is called an IP address. IP stands for internet protocol, if you didn’t already know. Your computer’s IP address doesn’t just uniquely identify your computer on the internet, it also gives away your geographical location.

When you try to log into a website, it immediately knows where you are from by analysing your IP address. If it has implemented regional restriction, it will block you. There are several ways to circumvent the restrictions, including the use of anonymous proxies and VPN. Proxies are not very reliable and, in any case, when will you have the time to find a proxy service provider when you are visiting a foreign country?  But if your company has implemented a VPN, you will have no trouble accessing any website.

A VPN, which is short for Virtual Private Network, is a method for adding an impenetrable layer of security and privacy when connecting your office network or home network to the internet or a public network. It makes the connection between your private network and the internet so seamless that you will not experience any difference in the way you access information and resources from the way you access the information and resources on your network.

When connecting to the internet or public network, the VPN establishes a point-to-point connection using a VPN networking protocol such as PPTP, L2TP and SSL protocol. These protocols allow your network to communicate with the internet. Using these protocols, you can connect your private network with any other networks via the internet. For example, you can connect your office network with your home network.

Now to go back to the point, when you use a VPN, it reroutes all your internet traffic through itself.  This means that your IP address will become invisible to the destination server, which will treat you just like any other visitor from the area where the server is located. Thus, VPN makes it possible for you circumvent regional restrictions, such as IP-based geolocation.

What Are The Most Popular VPN Protocols?

A virtual private network (VPN) is a method that allows you to connect your private network, such as your office LAN or home LAN, securely to the internet and to each other via the internet. It creates a virtual network that shields your physical network from hackers, malware and other security hazards emanating from the internet. A VPN connects your private network to the internet by establishing a virtual point-to-point connection using a networking protocol.

 

There are several networking protocols you can choose from for your VPN. Some of the most popular are:

 

  • Point-to-Point Tunneling Protocol (PPTP)

 

A Point-to-Point Protocol (PPTP) is a set of communication rules that allow an organization to implement a virtual private network (VPN). It is supported by almost every operating system, including Windows and Mac OS. However, lack adequate encryption and authentication features make it the least secure networking protocol.

 

  • Layer 2 Tunneling Protocol (L2TP)

 

A Layer 2 Tunneling Protocol (L2TP) is a set of communication rules that is used to support a VPN. It’s called a tunneling protocol because it encapsulates a another protocol, the Internet Protocol Security (IPSec), to carry a payload over an incompatible network. The L2TP relies on IPSec to provide encryption and confidentiality as it does not provide its own.

  • Internet Protocol Security (IPSec)

Internet Protocol Security (IPSec) is a set of protocols (called a protocol suite) that used cryptographic security services to provide security to IP communications during communication sessions by authenticating and encrypting the IP packets. It is used for protecting data during host-to-host and network-to-network communication. It is a highly secure network protocol.

 

  • Transport Layer Security (TLS)

Transport Layer Security (TLS) and its predecessor, Secure Socket Layer (SSL) protocol, are the most widely used security protocols on the internet and internal networks today. Because of their exceptionally high security level, they are used when a web browser wants to send sensitive data, such as a credit card number, to a web server.  The use of TLS and SSL on a VPN makes it virtually impregnable.

 

  • OpenVPN

OpenVPN is a freely available open-source VPN protocol that is based on the SSL code. It is great for creating point-to-point and site-to-site connections. It is secure and doesn’t have any connection issues. It is also capable of traversing firewalls and network address translator (NATs). However, it requires a client to be installed as it is not natively supported by Windows, Mac OS X and mobile devices.
