Create VPN using Python – Online privacy has become a key concern with the increase in digital transactions. Most people use the internet to shop, pay for utilities and subscriptions, and check their bank balances. All these processes involve sharing sensitive data, which could end up in the wrong hands. Intelligence organizations and internet service providers (ISPs) gather and use your data to create targeted ads. On the other hand, hackers want to steal the data to profit from it.

VPNs offer an effective solution for ensuring privacy and protecting your data. There are numerous VPN servers which guarantees online privacy, maximum coverage, and high-speed connectivity. It is important to choose a VPN server that meets all your needs.

This article will discuss how to code a VPN using Python. But first, let’s understand what a VPN is and how it works.

VPN: What It Is and How It Works

A Virtual Private Network (VPN) is a protected connection from a device to a network over the internet. It allows users to send and receive data over public and shared networks while maintaining privacy. A VPN will protect the user from interference, snooping, and censorship.

A VPN masks your IP address by redirecting traffic through a customized server managed by a VPN host. The VPN server, like VeePN, becomes your data source. This means third parties and your ISP cannot monitor what data you receive and send or what sites you visit. VPN servers also encrypt your online traffic, making it unusable if someone gets it.

VPNs have different types and numerous providers. Before choosing one, it is important to weigh them thoroughly. Most versions provide free trials, which allow you to test various features before you buy.

How Do I Create My Own VPN Network?

Python programming language is popular, and you can use it to create VPNs. But why use Python?

Python has numerous applications, including scientific computing, web development, systems administration, and data analysis. It also provides a free Python VPN Library that allows you to create a VPN with only basic technical know-how. Python is an open-source platform that offers all the tools you need to create a VPN.

Pros and Cons of Creating Your Own VPN

Creating your own VPN shifts your trust in a VPN company to a cloud service provider. Though it has benefits, it has its drawbacks too.

Pros

• Cost-effective: Creating your own VPN is cheaper than relying on a VPN server. VPN providers charge a monthly subscription. Furthermore, if you are using multiple servers, the VPN company will charge every location separately, and the cost will increase quickly.
• Disposable VPNs: Homemade VPNs use a cloud service instead of a VPN provider. This allows you to delete an entire session and make it appear as if it never existed.

Cons

• Censorship: Some countries have invested heavily in firewalls and have all cloud service providers on their radar. As a result, your VPN-assigned IP address will likely be blocked. You may need a VPN company to bypass the censorship.
• Unblocking streaming services: Homemade VPNs won’t work for you if you love streaming. Major streaming platforms block most cloud services.

How Do I Create My Own VPN Code?

Though you don’t need to be a developer, you need basic technical skills to create a Python VPN. Here’s how to code a VPN in Python.

Step 1: Select the Right Python VPN Library

Different types of VPNs are available, each with its unique features. Before coding one in Python, you need to research and determine which library meets your needs. Below are the most popular libraries:

• PyVPN: This library is specifically designed for writing Python VPNs. It is easy to use and comes with all the functions you need.
• OpenVPN Client: Though this library is more complicated than PyVPN, it has all the functions you need to code a functional Python VPN. It is also easy to use.
• Cisco IOS SSL VPN: Cisco developed this library and designed it specifically for building TLS or SSL-secured VPN tunnels between networks and Cisco devices. It is more complex and requires advanced skills in networking concepts. But it is a good option if you want a full network-level VPN to run from your router.
• PsychoPy: This library has a few benefits over the others, such as greater flexibility, and is more user-friendly.

Step 2: Install the Python VPN Library

You must install the library and create a VPN object to code a VPN in Python. The object handles all the information you need to build and manage your connection.

Then you must build a VPN instance class, which requires these two arguments:

• A server of IP address
• A port number that the VPN should use

You can pass optional arguments to specify certain VPN parameters, like whether to encrypt.

Step 3: Configure Your VPN Settings

You need to configure the VPN object with the right settings. Call the VPN object’s constructor using these parameters:

1. Your VPN name. E.g., ABC-VPN
2. The server’s IP address. E.g., 192.168.1.123
3. The server port, E.g., 1234
4. Your preferred encryption type. E.g., IKEv2 or IPSec
5. Password for connecting to the VPN.

Step 4: Connect the Python VPN to the Designated VPN Server

This step is the answers to, “How to connect VPN with Python.”

To connect with the VPN server, open a terminal window and key in this command:

python  -m 192.168.1.123  -p 1234

The command will launch the VPN server on port 1234. Enter the VPN credentials and press “Enter”.

Step 5: Test the VPN Connection

Open a terminal window and key this command to test your VPN connection.

ip   addr   show   etho   tunnel1

Then, use the ifconfig command to set up your PC to use the VPN server’s IP address. Type this command.

ifconfig tun0 10.8.0.2 pointopoint 10.8.0.1 netmask 255.255.255.252

Finally, use a ping tool to check if the computer can access the VPN server.

Conclusion – Create VPN using Python

VPNs are essential tools for protecting your online privacy. You can read honest reviews before using reputable VPN providers like VeePN or create your own VPN. This article provided a step- by-step guide on how to code a VPN with Python.
