Setting up a VPN between offices in 2026

Modern business requires reliable and secure communication between offices, especially in the context of constant blockages and restrictions. Setting up a VPN between offices helps solve this problem by ensuring data protection and the ability to bypass blockages. In this guide, I will share my experience in setting up a VPN, choosing protocols, and testing speed.

What is a VPN and why is it needed for offices?

A VPN (Virtual Private Network) is a technology that allows for the creation of secure connections over public networks. It encrypts transmitted data, making it inaccessible to outsiders.

Definition of VPN

A VPN creates a secure connection between devices, ensuring the confidentiality and security of transmitted information. This is especially important for businesses, as client data and financial information must be protected from leaks.

Advantages of using a VPN

Using a VPN in offices brings many advantages, such as:

• Data security: encryption protects information from unauthorized access.
• Bypassing blockages: a VPN allows you to bypass blockages on sites like YouTube, TikTok, and others.
• Remote access: employees can securely connect to the corporate network from anywhere in the world.

Bypassing blockages

In Russia, many websites and services are blocked by Roskomnadzor. Setting up a VPN between offices allows you to bypass these blockages, providing access to necessary resources. For example, using a VPN, you can access Facebook or Twitter, which often become unavailable.

Choosing a protocol for setting up a VPN

There are several protocols for setting up a VPN, each with its own advantages and disadvantages. Let's take a closer look at them.

Comparison of protocols: WireGuard, OpenVPN, IKEv2

WireGuard is a modern protocol that offers high speed and ease of setup. In my experience, its performance is significantly better than that of OpenVPN and IKEv2.

OpenVPN is the most widely used and time-tested protocol that provides a high level of security but may be slower due to complex setup. IKEv2, on the other hand, is good for mobile devices as it quickly restores the connection after a loss.

Shadowsocks and VLESS/XRay

Shadowsocks is a proxy protocol that is often used to bypass censorship. It works faster than traditional VPNs but is not as secure. VLESS and XRay are newer protocols that offer additional features and flexibility, but their setup can be more complicated.

How to choose the right protocol

The choice of protocol depends on your needs. If speed and simplicity are important to you, try WireGuard. For maximum security, OpenVPN is suitable. If you move around frequently, IKEv2 will be the best choice.

Step-by-step guide to setting up a VPN between offices

Now let's move on to the practical part — setting up a VPN between offices. I will outline the necessary steps and provide tips for each stage.

Preparing equipment

First, make sure you have all the necessary equipment: routers, servers, and computers. Ensure that the devices support the protocol you have chosen.

Setting up on Windows

To set up a VPN on Windows, follow these steps:

1. Open "Settings" and select "Network & Internet."
2. Click on "VPN" and select "Add a VPN connection."
3. Enter the required information: connection name, VPN type, and server address.
4. Save the settings and connect.

Setting up on Mac

For Mac, the process is similar:

1. Open "System Preferences" and select "Network."
2. Click on "+" to add a new connection.
3. Select "VPN" and enter the connection details.
4. Save and connect.

Setup on Android and iOS

On mobile devices, the setup is also simple:

• Download your VPN provider's app.
• Enter the connection details and save the settings.
• Connect through the app.

Setup on routers

Setting up on routers allows you to connect all devices on the network to the VPN:

1. Access the router settings through the web interface.
2. Select the "VPN" section and enter your connection details.
3. Save the changes and restart the router.

Speed testing and troubleshooting

After setting up the VPN, it's important to check the speed and ensure everything is working correctly.

How to conduct a speed test

There are many online services for speed testing, such as Speedtest.net. Just run the test before and after connecting to the VPN to see the difference.

What to do if the speed is low

If you notice that the speed is low, try the following:

• Change the server you are connecting to.
• Try a different protocol.
• Restart your device and router.

Connection issues and their solutions

If there are connection issues, check the VPN settings. Make sure all details are entered correctly and check your internet connection. If the problem persists, contact your provider.

Setting up a VPN in unstable internet conditions

Setting up a VPN can be a challenging task if you have an unstable internet connection. This often leads to connection drops and performance issues. It's important to consider several factors to minimize these problems.

First, choose a provider that offers servers in your region. This can significantly reduce latency and improve connection stability. Second, ensure that your equipment meets the requirements. Modern routers and devices handle loads better and provide higher speeds.

If you experience persistent connection issues, try using automatic failover features to a backup server if the primary becomes unavailable. Many VPN services, including NvoVPN, offer this capability.

Using a VPN on old devices

Old devices may not support modern VPN protocols or may work slower when using a VPN. I encountered this when trying to set up a VPN on an old laptop with Windows 7. In such cases, it's important to optimize the settings.

Try using less demanding protocols, such as IKEv2, or even PPTP if security is not as critical. You can also reduce encryption to lessen the load on the processor.

It's important to remember that using a VPN on old devices may lead to higher battery consumption, so keep an eye on the charge level during long connections.

Compatibility with corporate systems

When setting up a VPN between offices, it is important to consider compatibility with existing corporate systems. Some companies use specific software solutions that may conflict with the VPN.

Before setting up, be sure to check if your software supports VPN operation. For example, accounting programs or CRM systems may require special settings for proper operation through the VPN. I recommend testing each system separately after setup.

Also, don't forget to update all devices to the latest software versions. This will help avoid vulnerabilities and improve the overall security of your network.

VPN performance optimization

After successfully setting up the VPN, it is worth paying attention to its optimization. This will improve connection speed and increase stability. Here are some tips:

• Regularly update your VPN software. This not only improves security but can also enhance performance.
• Use DNS servers that work faster. For example, Google DNS (8.8.8.8 and 8.8.4.4) often provides better results.
• Check for updates for your hardware and drivers. Sometimes outdated hardware can be the cause of low speed.
