How to Use WireGuard VPN: Detailed Guide

In February 2019, Astrill became one of the very few virtual private network (VPN) providers to offer WireGuard as part of its services. It is aimed at providing a fast connection, tighter security, and enhanced encryption with a much simpler architecture compared to IPSec and OpenVPN. 

Because the protocol uses cryptography and is easier to set up and manage, it is touted as one of the most secure tunneling protocols in virtual privacy technology.

This release reflects Astrill’s superior

security expertise and aligns with our mission to provide continuous support for our users’ advanced and diverse needs.

Here’s some more critical information to understand why WireGuard VPN is a much safer bet for various applications.

What is WireGuard VPN?

WireGuard is a simple tunneling vpn protocol used to implement VPN techniques across various configurations. It is relatively faster, more efficient, and more secure than existing protocols adopted by standard VPN providers. 

Its smaller size and simple architecture enjoy support from developers owing to the ease of peer review and auditing. The small codebase (1% of that of OpenVPN) further ensures better prevention of security attacks.

A free and open-source software application, WireGuard is promoted as an experimental code by its developers. It is for this reason that Astrill recommends its usage for non-critical applications.

The protocol offers impeccable speed and encryption due to its dependence on some of the leading technologies in the data security industry. It utilizes ChaCha20 for encryption, Poly1305 for data authentication, and Curve25519 for crucial exchange. All of this has been a result of a lengthy and thoroughly considered academic process.

How does WireGuard VPN work?

WireGuard creates an encrypted tunnel between two devices using state-of-the-art cryptography and network code. It even works when the client device’s IP address changes, thanks to its smartly developed mechanism.

For example, If you switch your network between your mobile data and your Wi-Fi, you will not have to wait for a single second for the VPN to reconnect. The connection will remain established during this switch of networks. 

Benefits of using WireGuard VPN

Ease of Use

Due to its shorter code base, and simple yet smart mechanism, it is easy to use. 

Security

It is one of the toughest and most-secure VPN protocols because of the modern cryptography implemented in its development.

Stability

It is the most stable VPN protocol that stays connected and stable even in bandwidth fluctuations that cause other VPN protocols to disconnect. WireGuard can work perfectly even in poor network connections and it even stays connected during network switching. 

Speed

Thanks to its modern cryptographic implementation and shorter code base, it works faster than any other VPN protocol. It is developed to optimize the speed and to ensure seamless bandwidth provision. 

Salient Features of the WireGuard Protocol by Astrill

Apart from its research-based solid origin, there is plenty more that WireGuard can achieve as a standard protocol. Here’s a list of some of its most salient features and how they will help you enjoy a better VPN experience.

  • High speed and latency owing to minimal architecture; this is one of the most significant factors for users when choosing a VPN
  • Smaller attack surface than other protocols; this means less vulnerability from hackers and phishers
  • A smaller codebase also means easier development and redevelopment
  • Usage of state-of-the-art cryptographic cipher suite for encryption
  • Added facility for roaming between Wi-Fi and 4G connections.

Besides, the highlight of Astrill’s support for WireGuard is that we have automated the process of key generation and execution, which is an integral part of its overall implementation. 

Typically, users of a VPN provider that offers this advanced protocol have to generate keys and upload them to the servers manually. This is partly because the protocol is still at a nascent stage of development. 

This is also one of the reasons why we do not recommend using it for applications where security is critical. But experimenting with its latency and trying out different applications to match your needs is something you can do readily with our native clients.

How to Switch ON WireGuard VPN on Astrill?

If you are an Astrill user, setting up your application client will just take a few seconds. Run the application on your preferred device and select WireGuard VPN. Ensure that you are connected by toggling the ON/OFF switch. And you are ready to experience what is touted as the future of VPN technology.

If you are running an old version of Astrill, you may need to update it. If you face any difficulties, get in touch with our support team.

How to Set Up a WireGuard VPN

WireGuard VPN is available on Astrill along with our other strong OpenWeb and StealthVPN protocols. It is compatible with Windows, Android, macOS, iOS and FireTV. 

Follow the procedures mentioned below to see how you can setup WireGuard VPN on your device:

Windows

  1. Open Astrill VPN app on your PC or Laptop.
  2. Sign-in to your account.
  3. Make sure that your VPN connection is off. Click the drop down menu the top right of your screen.
  4. Select the “WireGuard” from the list.
  5. Now click the connection toggle button to turn on the VPN connection.
  6. Once the connection is On, it means that WireGuard is active on your device. 

Android

Follow these simple steps to install WireGuard on Android:

  1. Download and install the Wireguard Android app from Google Play Store.
  2. Launch the app after installation.
  3. Click the ‘+’ icon located at the bottom of the screen.
  4. Click on ‘Import from file or Archive’.
  5. Now import the configuration file you have received from Astrill VPN. (The file may be available in the email or you can download it from the server).
  6. After completing the import, click on the toggle button located next to the name of the connection.
  7. Click Ok when the warning prompts. 
  8. Now you can use WireGuard on your Android device. 

Why is WireGuard important?

WireGuard is simple to configure and is very fast compared to previous standards. Options like IPSec and OpenVPN were huge, poorly-audited codebases that could have contained all sorts of security vulnerabilities lurking below the surface. WireGuard simplifies all of this – and offers a better final product.

FAQs

What port does WireGuard use?

The default port of WireGuard is 51820/UDP.

Is WireGuard better than OpenVPN?

Yes, WireGuard is a better and faster option as compared to OpenVPN. In fact, it is easier to set-up than OpenVPN, which means that it is better in all aspects. 

Is WireGuard multithreaded?

Yes, WireGuard is multithreaded as it can take the benefit of multiple CPU cores for optimized performance

Does Astrill support WireGuard?

Yes, Astrill VPN supports WireGuard and has this protocol integrated in all of its VPN clients for various operating systems and devices. 

Is WireGuard safe for torrenting?

Yes, WireGuard is safe for torrenting. Many people prefer P2P protocol for torrenting but Wireguard is also a great option for bandwidth-intensive activity. 

Is WireGuard secure?

WireGuard uses modern cryptography, which makes it one of the safest VPN protocols. It does not compromise server speed and does not break connection when switching between the networks, which makes it safer. 

Is WireGuard better than other protocols?

Yes! Due to its optimized cryptography the fact that it processes within Linux kernel, it is indeed a faster and safer option than other protocols.
