The world is a scary place. The digital space is even more frightening. Security and privacy of our data have never been more critical. So many transactions today are carried out online from banking to shopping to catching up with friends. This has significantly increased our vulnerability to online threats. For example, when you visit a website on the internet, the website can use your IP address to ping your exact location and learn your identity. You can use a VPN to prevent this from happening and guarantee your security and privacy.
VPN stands for Virtual Private Network which is programming that secures and encrypts a connection over a public network. With VPN, you can send and receive data safely between your computer and the internet. The VPN routes your data through its servers before sending it to the website you are visiting so that no one is able to determine your identity and location. The data is carried through a secure VPN tunnel in an encrypted state to protect it from unauthorized hacker sniffing.
Apart from online security, there are many other benefits of using a VPN router, including bypassing censorship and access to region-restricted content, among others.
What’s a VPN Router?
VPN pass-through functionality is supported by most standard Wi-Fi routers. A VPN user on a remote computer can install software on their remote device and initiate a VPN connection with their home or company’s network from any location. With a standard router, however, you must install the VPN software on every device before you can use it to connect to your VPN network. Once one remote device has logged in to the system, the connection cannot be shared with other devices on that network.
A VPN router, on the other hand, has a VPN installed directly into it. It has firmware that can handle VPN connections, meaning it establishes a secure connection for the entire site at the hardware level. With a VPN router, you can connect all your devices to your VPN network without having to make individual software installations. All connected devices-computers, smartphones, tablets, and smart TVs- can simultaneously receive continuous network access.

What is a VPN Protocol?
In addition to selecting the best VPN for your home or business needs, you must also choose the best VPN protocol for your needs. A VPN protocol is basically a set of encryption standards and transmission protocols that VPN providers use to give their clients secure and stable VPN client-VPN server communications.
There is a range of VPN protocols available in the market today, and one of the most popular protocols is L2PT. It has no known vulnerabilities, and its double encryption provides users maximum security over the internet.
Everything about L2TP VPN
An L2TP VPN is a VPN service that provides access to L2TP protocol. It is common for VPN providers to offer L2TP in combination with IPSec to secure the data and traffic of their clients.
As its name suggests, Layer 2 Tunneling Protocol (L2TP) is a computer networking protocol used to tunnel L2 traffic over an IP network. It features the best of both Cisco’s’ Layer 2 Forwarding (L2F) and Microsoft’s Point to Point Tunneling Protocol (PPTP) and improves on them. The primary purpose of L2TP is supporting Virtual Private Networks.
By itself, L2TP does not offer any encryption. As such, it is usually paired with IPSec utilizing a process called double encapsulation. One encapsulation sets up the PPP connection and the second encapsulation contains the IPSec encryption. This double encapsulation adds an extra layer of encryption, making the L2TP protocol more secure than PPTP. Double encapsulation with IPSec enables L2TP to use encryption keys of up to 256-bit. The downside to improved security is that L2TP-IPSec is much slower and more resource-intensive than PPTP.
The L2TP is made up of two components, the L2TP Network Server (LNS) which authenticates and terminates the PPP stream and the L2TP Access concentrator (LAC) which physically terminates a call.
How does L2TP protocol work?
The L2TP protocol has two endpoints on the internet –the LAC and the LNS. Tunneling on the protocol begins when a connection is initiated between these two endpoints. After the connection has been established, a PPP link layer is enabled, encapsulated, and carried across the network.
Once you, the end-user, have initiated the PPP connection with the ISP and the LAC has accepted this connection, the PPP link is established. A free slot within the network tunnel is then assigned, followed bypassing of the request on to the LNS.
A virtual PPP interface is finally created when the connection has been fully authenticated and accepted. Link frames can now be freely passed through the tunnel and approved by the LNS which proceeds to remove the L2TP encapsulation and processes them as regular frames.
Encryption: L2TP protocol does not provide secure encryption on its own. L2TP/IPSec protocol supports up to 256-bit session keys, but this varies according to the algorithms in use. It works with 3DES or AES algorithms for improved encryption
Port Configuration: It uses Protocol 50, UDP 500 for key exchange, UDP 1701 for configuration, and UDP 4500 NAT
VPN Speeds: On its own, L2TP is very fast, but while using data encapsulation for improved security, speeds are relatively lower compared to Open VPN and PPTP
Compatibility: Most devices and operating systems
Advantages of using the L2TP protocol
- Provides high data security when paired with IPSec
- L2TP/IPSec is supported and readily available in all operating systems and modern devices
- The protocol supports multithreading for improved performance
- For users with VPN authentication, the protocol provides the best authorization policy
- It is an industry-standard in the business sector
- There is no overhead cost after implementation making it very cost-effective
- It is flexible, reliable and scalable meaning it is available on both desktop and mobile operating systems
- Setting up is relatively easy and painless
Drawbacks of using the L2TP protocol
- It has to be paired with IPSec to provide proper internet security
- Its double encapsulation feature makes it slower and more resource-intensive compared to other VPN protocols
- NAT firewalls can block L2TP unless the protocol is further configured to bypass them. This makes configuration on devices that run on NAT routers quite difficult
- Allegations have been made about its weakened state as a result of interference by the NSA although hard proof has not been provide
How to set up an L2TP VPN router?
The L2TP protocol is natively supported on Mac OS and windows, but it can run on multiple platforms. The whole setup process, regardless of the platform, is relatively painless. There are step-by-step guidelines on how to set up an L2TP VPN on the various operating systems. For example, on Windows and Mac OS devices where the protocol is natively supported, setting up L2TP involves following clearly laid down steps in the Network Settings to establish and configure the connection.
How to install an L2TP VPN on your router?
Installing an L2TP VPN on your router is relatively easy if you follow the instructions provided by your VPN provider. Before you begin the installation process, make a note of your default, internet settings in case you wish to revert to them later.
Each installation process differs depending on the VPN provider, but the essential first steps are:
- Launch your internet browser on your mobile device or computer connected to the router’s network.
- Find your server address and account credentials to log in to your router network
- On the home screen, select the ADVANCED tab to set VPN service setting
- Configure your TP-Link router by following instructions from your provider.
