Can a NAS be used as a VPN?

Answered by James Kissner

A NAS (Network Attached Storage) can be used as a VPN (Virtual Private Network) server. In fact, many NAS devices, including those from Synology, have built-in VPN server functionality.

Setting up a VPN server on a Synology NAS is a straightforward process. Synology provides a user-friendly interface that allows you to configure and manage the VPN server settings easily. By enabling the VPN server on your NAS, you can create a secure and encrypted connection between your remote devices and the NAS, allowing you to access resources on the NAS as if you were physically present in the same network.

There are several benefits to using a NAS as a VPN server. Firstly, it provides a convenient way for remote users to access files, folders, and other resources on the NAS securely. This is especially useful for businesses or individuals with multiple locations or remote workers who need to access centralized data.

Secondly, using a NAS as a VPN server adds an extra layer of security to your network. By establishing a VPN connection, all data transmitted between the remote device and the NAS is encrypted, ensuring that sensitive information remains secure and protected from unauthorized access. This is particularly important when accessing resources over untrusted networks, such as public Wi-Fi hotspots.

To set up a VPN server on a Synology NAS, you need to follow these general steps:

1. Ensure that your Synology NAS is connected to the internet and has a valid IP address.

2. Log in to the DSM (DiskStation Manager) interface of your Synology NAS. This is the web-based management interface for your NAS, which can be accessed through a web browser.

3. Open the “Control Panel” and navigate to the “VPN Server” settings. The exact location may vary slightly depending on the version of DSM you are using.

4. Enable the VPN server and choose the desired VPN protocol. Synology supports various VPN protocols such as OpenVPN, PPTP, and L2TP/IPSec. It is recommended to use OpenVPN or L2TP/IPSec for better security.

5. Configure the VPN server settings, including the network settings, authentication methods, and encryption options. You can choose to use a local user database or integrate with an external authentication server, such as LDAP or RADIUS.

6. Specify the IP address range for VPN clients and set up any additional options or restrictions, such as split tunneling or client access permissions.

7. Generate and distribute VPN client configuration files or setup instructions to the remote users who will be connecting to the VPN server. The Synology NAS provides options to download the necessary client software or configuration files.

8. Remote users can then use the provided client software or configuration files to establish a VPN connection to the NAS. They will need to enter the NAS’s public IP address or hostname, along with the appropriate authentication credentials.

By following these steps, you can create a VPN server using a Synology NAS, allowing remote users to securely access resources on the NAS from different locations. This can greatly enhance collaboration and productivity, as well as provide a secure method for accessing sensitive data.

In my personal experience, I have set up VPN servers on Synology NAS devices for both personal and business use. It has proven to be a reliable and convenient solution for securely accessing files and resources remotely. Whether I needed to access documents from a different office location or share files with remote team members, the VPN server on the NAS provided a seamless and secure connection. The setup process was straightforward, and the Synology DSM interface made it easy to configure and manage the VPN server settings.
