We forecast our global VPN hardware requirements will reach 500+ million devices in 2022. With the limited IPv4 address space and the mass adoption of mobile platforms and cloud computing, these figures can rise dramatically as more people use VPNs to gain cyber security and anonymity.
In the VPN market, technology experts have increasingly used VPNs, and this development has recently been driven by ISPs selling browsing histories worldwide. With VPNs, users can closely protect their online privacy and access other benefits like better security when using public internet networks.
Every year the requirements for VPN hardware go up and up. If you are shopping for a VPN router or just wondering what your needs will be in 2022, then read on.
Choosing the right hardware VPN depends heavily on your requirements and use case. This blog will help you identify some of the best VPNs for your needs.
What is OpenVPN?
OpenVPN is a VPN software and protocol that uses various techniques to secure point-to-point and site-to-site connections. It is not a VPN provider.
OpenVPN is a free, open-source protocol especially developed to create highly secure virtual private network connections. Currently, it is one of the most well-liked VPN protocols among VPN users.
OpenVPN is programmed by James Yonan and released in 2001. It is one of the open-source VPN protocols that also has its own application. Like other security protocols, OpenVPN is a standalone tunneling protocol even though you can enjoy the greatest security and benefit from the features of a virtual private network with a quality vendor.
It has built a robust reputation for being the strongest encryption protocol for many valid reasons. These include the data that it uses pre-shared keys, authentication, certification, IPv6 support, OpenSSL encryption, and it can adapt UDP and TCP to bypass the strictest firewalls and DPI.
How Does OpenVPN Work?
OpenVPN is an open-source and free software application that implements VPN techniques to create protected site-to-site connections in routed or bridged configurations. It uses a custom security protocol that uses SSL/TLS for key exchange. It can traverse network address translators (NATs) and firewalls.
OpenVPN works by using the TCP or UDP protocols to create a secure connection between two endpoints – similar to how your Internet browser uses TCP/IP to connect to a site. It is better than the default Remote Desktop Protocol because it allows you to tunnel through firewalls and proxies and uses multi-threading for robust performance.
OpenVPN allows peers to verify each other using certificates, a pre-shared secret key, or username/password. When used in a multi-client server configuration, it will enable the server to release an authentication key for every client, using signature and Certificate authority. It uses the OpenSSL encryption library broadly, as well as the SSLv3/TLSv1 protocol, and contains many security and control features.
Is OpenVPN secure to Use?
Yes, OpenVPN is one of the most secure and protected VPN protocols you can use right now.
OpenVPN is an open-source VPN protocol that has gained popularity over the years for one main reason: it’s highly secure. With 256-bit AES encryption, it would take a hacker 1 billion years to crack your connection (for comparison, PPTP uses 128-bit encryption and takes about 10 hours).
OpenVPN also provides a high level of privacy by using shared IP addresses, which means that multiple users are connected on a single server. This makes it hard to identify a specific user while they’re browsing the web.
So, how secure is OpenVPN? It’s not just secure, but there’s no better security method available right now. The only downside to OpenVPN is that it can be slower than other protocols because it uses advanced encryption methods. However, if you want security and privacy above all else, OpenVPN is the way to go.
What is better than OpenVPN?
PPTP is an easy-to-use and fast protocol, and it is a perfect choice if OpenVPN is not supported by your phone or PC. L2TP/IPSec is another excellent option if OpenVPN is not supported and security is your top priority. OpenVPN is the protocol that is recommended for desktops including Windows, Linux, and Mac OS X.
Is PPTP or OpenVPN Better?
PPTP has faster speed and is simple to set up but provides a poorly secured internet connection. On the other hand, OpenVPN offers excellent speed and powerful security, plus it is great at circumventing geo-restrictions and firewalls undetected.
Is WireGuard Better than OpenVPN?
OpenVPN and WireGuard are both great in different ways. WireGuard is newer and faster, but OpenVPN has been around for a long time and offers more security. WireGuard consumes 15% less data, handles network changes better, and appears just as secure. However, OpenVPN is more privacy-friendly and is supported by many VPN services.
OpenVPN hardware requirements
The essential thing is to buy hardware enough to handle your internet connection without hiccups. One of the most crucial hardware components for VPN is the CPU. OpenVPN heavily depends on the CPU for decryption or encryption of traffic. Other components such as network interfaces, memory, or disk are far less critical.
Here is a list for selecting VPN hardware:
- Your CPU must support AES-NI.
- OpenVPN protocol is unable to use multi-core CPUs. Make sure the single-thread performance of your CPU is powerful to encrypt or decrypt your online traffic in real-time.
- You must have 1GB minimum memory for the number of connections you need to maintain.
- OpenVPN does not need much space. 4GB should be enough for the logs and system. If you are intended to keep logs for the long term, you may consider a big hard disk.
Why is AES-NI important for VPN?
AES-NI is a new encryption instruction set baked right into the CPU that significantly speeds up cryptography tasks such as decryption/encryption for VPN or SSL. Intel initially developed AES-NI, but most modern AMD CPUs also support it now.
If you are looking for OpenVPN hardware in 2021, you must be careful to evade the low-end CPUs such as Intel J1800 or J1900 that don’t support native encryption.
Best VPNs for OpenVPN
TechNinjaPro has put together a list of best OpenVPN clients; all the VPN services implement strong OpenVPN encryption to the utmost standard and have custom VPN clients, meaning they are extremely simple to set up.
PureVPN is undoubtedly one of the best VPNs for OpenVPN. If you are looking for a quick answer on which VPN services offer strong OpenVPN encryption, TechNinjaPro has rounded up its top recommendations below.
Which router Operating System should you use for OpenVPN?
There are two significant groups of operating systems
- Linux-based: OpenWRT, IPFire
- BSD-based: pfSense, OPNsense, etc
All of these systems work perfectly with OpenVPN. OPNsense and pfSense are easier to set up and manage. OpenWRT is a bit harder to set up, but it is about 40% more performant. TechNinjaPro recommends pfSense and OpenWRT.
OpenVPN hardware appliances
TechNinjaPro has listed the OpenVPN hardware appliance recommendations below:
- APU2Do: Entry-Level OpenVPN box
- C4 OpenVPN router
- TLSense i7: the Gigabit OpenVPN router
Frequently Asked Questions
At least, you must start with 1GB of memory and add approx 1GB for every 150 connected devices.
The virtual private network gateway needs to be connected to the internet, preferably with a static IP address to map its dynamic IP address to a hostname. Configuration is easiest if the VPN gateway is also the router of its network.
The OpenVPN is free to use if you keep to the software license agreement, but the commercial OpenVPN Access Server product sold by OpenVPN Inc is not free.
OpenVPN provides the highest level of encryption and security and is recommended for safe web surfing. For this reason, most top VPN providers use it as their primary shield against cyber threats and as a key to bypassing geo-restrictions.
The OpenVPN community is proud to release OpenVPN 2.5.0, the newest version with many new features.
OpenVPN is certainly the most robust encryption protocol if you want to surf the internet anonymously and get around the most internet service providers and firewalls to access geo-restricted websites. OpenVPN is flexible and well-managed and connects a wide range of servers.
