3. Create Volumes and Shared Folders: After DSM installation, create volumes and shared folders to organize your data effectively. Navigate to the Control Panel and click on “Shared Folder” to create and manage your shared folders.
4. Network Settings: Go to Control Panel > Network and configure your network settings. Ensure your NAS is connected to a stable network with a static IP address for consistent remote access.

Enabling FTP Service on Synology DS218+

Once your NAS is set up, the next step is to enable and configure the FTP service. Here’s how to do it:

1. Access Control Panel: Log in to DSM and open the Control Panel.
2. Enable FTP Service: Navigate to File Services > FTP. Check the box to enable FTP service. You will see options to configure FTP, SFTP, and FTPS. For secure remote file access, it is recommended to enable FTPS.
3. Configure FTP Settings: Set the port number (default is 21) and specify the maximum number of connections. You can also set up passive mode to facilitate connections through NAT/firewall.
4. Apply Security Settings: Enable encryption by checking the “Enable FTP over SSL/TLS” option. This ensures that the data transferred between the server and clients is encrypted, enhancing security. Click “Apply” to save your settings.

Creating and Managing User Accounts

To control who can access your FTP server, you need to create and manage user accounts. Here’s what you need to do:

1. Create User Accounts: Go to Control Panel > User & Group. Click “Create” to add new users. Fill in the necessary details such as username, password, and email.
2. Assign Permissions: Set appropriate permissions for each user. Navigate to the Permissions tab and assign access rights to the shared folders. This ensures that users can only access the folders they are authorized to.
3. Set Quota Limits: To manage storage effectively, you can set quota limits for each user. This controls the amount of storage space a user can consume.
4. Configure FTP Access: Go to the “Application” tab and ensure that FTP permissions are enabled for each user. This step is crucial for users to be able to access the FTP server.

Enhancing Security for Your FTP Server

Securing your FTP server is paramount to protect your data from unauthorized access. Here are some critical steps:

1. Enable Firewall: In DSM, go to Control Panel > Security > Firewall. Create firewall rules to allow only specific IP addresses or ranges to access your FTP server.
2. Use Strong Passwords: Ensure that all user accounts have strong, unique passwords. Avoid using common passwords that can be easily guessed.
3. Enable Two-Factor Authentication (2FA): Enhance security by enabling 2FA for DSM login. This adds an extra layer of security by requiring a verification code in addition to the password.
4. Set Up Security Advisor: Utilize the Security Advisor tool in DSM to scan your system for potential security risks and get recommendations to improve your NAS security.
5. Regular Updates: Keep your DSM and all installed packages updated. Regular updates ensure that security vulnerabilities are patched timely.

Remote Access and Mobile Integration

To facilitate remote file access, you can configure remote access settings and integrate mobile devices with your Synology NAS. Here are the steps:

1. QuickConnect: Use Synology’s QuickConnect service for easy remote access. Go to Control Panel > QuickConnect, enable it, and follow the instructions to set up your QuickConnect ID.
2. Dynamic DNS (DDNS): If you prefer using a domain name, set up DDNS. Navigate to Control Panel > External Access > DDNS and configure your preferred DDNS service.
3. Mobile Apps: Install Synology’s mobile apps such as DS file, DS video, DS audio, and DS photo on your mobile device. These apps allow you to access and manage your files, videos, audio, and photos remotely.
4. VPN Setup: For an extra layer of security, set up a VPN server on your Synology NAS. Go to Package Center, install the VPN Server package, and configure the settings. Connecting through a VPN ensures that your data is encrypted and secure during transit.

Setting up a secure FTP server on your Synology DS218+ for remote file access involves several critical steps, from initial configuration to advanced security setup. By carefully following these steps and leveraging the robust features of the Synology DiskStation Manager (DSM), you can ensure that your data is both accessible and secure.

The Synology DS218+ is an excellent choice for creating a secure FTP server due to its powerful hardware, user-friendly DSM, and extensive support for various file-sharing protocols. Whether you are a business aiming to enhance productivity or an individual needing reliable remote access to your files, a well-configured Synology NAS will meet your needs while keeping your data secure.
