How do you set up a secure FTP server using a Synology DS220j for remote file access?

12 June 2024

In today's digital landscape, managing and securing data has become crucial. The Synology DS220j Network Attached Storage (NAS) device, with its robust operating system (DiskStation Manager, or DSM), offers a seamless solution for file storage and sharing. This article provides a detailed guide on setting up a secure FTP server using a Synology DS220j, ensuring that you can easily access your files remotely.

Getting Started with Synology DS220j

The first step in setting up your secure FTP server is ensuring your Synology NAS is correctly configured and connected to your network. Begin by unboxing your DS220j and installing the hard drives. Once completed, connect the NAS to your router using an Ethernet cable and power it on.

Setting Up Synology DSM

Upon powering up, access the Synology control panel by entering the IP address of the NAS in your web browser. Follow the on-screen instructions to install the latest version of DSM. After installation, create a Synology account and log in to the DSM interface. This powerful operating system will be your primary tool for configuring and managing your NAS.

Creating Shared Folders

To organize your files, create shared folders within the DSM. Navigate to the "File Station" and click "Create" followed by "New Shared Folder." Assign a name and select permissions for the folder, ensuring you have complete control over who can access and modify the files stored within.

Setting Up User Accounts

Setting up user accounts is essential for managing access to your files. In the DSM control panel, go to "User & Group" settings. Create new user accounts with specific access rights and file permissions. This ensures that only authorized users can access the shared folders on your NAS.

Configuring the FTP Server on Synology DS220j

With the initial setup complete, you can now proceed to configure the FTP server on your Synology DS220j.

Enabling the FTP Service

To get started, navigate to the DSM control panel and select "File Services." Here, you'll find the option to enable FTP. Tick the checkbox next to "Enable FTP service" and click "Apply." This action activates the FTP service on your NAS, allowing for file transfer over the network.

Configuring FTP Settings

After enabling the FTP service, click on the "Advanced Settings" button to fine-tune your configuration. Here, you can set the maximum number of simultaneous connections, define the port number, and enable encryption options for a more secure connection. For enhanced security, enable FTPS, which encrypts the data transferred between your server and clients.

Setting Up FTP Users

Next, configure the user accounts that will have access to the FTP server. Navigate back to the "User" settings in the DSM control panel. For each user, you can specify FTP permissions, ensuring that only authorized individuals can access your files remotely. Additionally, enforce strong passwords and consider enabling two-factor authentication for an added layer of security.

Ensuring Secure Remote Access

Remote access to your FTP server requires a few additional steps to ensure security and functionality.

Configuring Port Forwarding

To access your NAS remotely, you'll need to configure port forwarding on your router. Log in to your router's web interface and locate the port forwarding settings. Forward the FTP port (default is 21) to the internal IP address of your Synology DS220j. This action opens a pathway for remote connections to your NAS.

Setting Up Dynamic DNS

Dynamic DNS (DDNS) provides a user-friendly way to connect to your NAS remotely, even if your IP address changes. In the DSM control panel, navigate to "External Access" and select "DDNS." Choose a DDNS provider and follow the instructions to configure your unique domain name. This domain will be used to access your FTP server from anywhere.

Conducting a Speed Test

Before relying on your FTP server for critical tasks, perform a speed test to ensure optimal performance. Use DSM's built-in tools or third-party applications to test the network speed and verify that your NAS can handle the desired file transfer rates. This step is vital for maintaining a smooth and efficient backup and file sharing experience.

Utilizing Synology Package Center

The Synology Package Center offers a range of applications to enhance the functionality of your NAS. Here are some packages that can complement your FTP server setup:

Synology Drive

Synology Drive transforms your NAS into a versatile private cloud. This application allows you to synchronize files across multiple devices, ensuring that you have access to your data from anywhere. It also supports file sharing and backup features, making it an excellent companion for your FTP server.

File Station

The File Station application is a powerful file management tool within DSM. Use File Station to manage your shared folders, move files, and set permissions. It offers a user-friendly interface for organizing your data and ensures that you can easily navigate through your NAS.

Video Station

If you need an efficient way to manage and stream your multimedia files, consider installing Video Station. This application allows you to organize and stream videos stored on your NAS to various devices, including mobile phones, tablets, and smart TVs. It integrates seamlessly with your FTP server, providing a comprehensive solution for multimedia file sharing.

Monitoring and Maintaining Your Synology DS220j

Once your FTP server is up and running, regular monitoring and maintenance are essential to ensure its longevity and performance.

Regular Backups

Regular backups are crucial for protecting your data against loss or corruption. DSM offers several backup solutions, including Hyper Backup and Snapshot Replication. Schedule routine backups to external drives or other network locations to safeguard your important files.

Monitoring System Health

DSM provides various tools for monitoring the health and performance of your NAS. Check the control panel regularly to monitor disk health, system logs, and resource usage. Address any warnings or errors promptly to maintain the stability of your FTP server.

Security Updates

Keep your DSM and installed packages up to date with the latest security patches and updates. Enable automatic updates in the control panel to ensure that your NAS is always protected against vulnerabilities. Regular updates are vital for maintaining a secure and reliable file sharing environment.

Setting up a secure FTP server using a Synology DS220j enables convenient and reliable remote access to your files. By following the steps outlined in this article, you can configure your NAS, enable FTP services, and secure your data effectively. With proper user account management, port forwarding, and the use of complementary applications from the Package Center, your Synology NAS will become a powerful tool for file storage, backup, and file sharing.

Remember to conduct regular backups, monitor system health, and apply security updates to maintain the integrity and performance of your FTP server. By leveraging the robust features of the Synology DS220j and DSM, you can ensure that your files are always accessible and secure, no matter where you are.
