VPN on NAS: Protect Your Synology & QNAP Network Storage (2026)

A NAS (Network Attached Storage) is your personal cloud — files, backups, photos, and media accessible from anywhere. But exposing a NAS to the internet without a VPN is a security risk. A VPN on your NAS means:

• Secure remote access: Access your files from anywhere through an encrypted tunnel
• Protected downloads: Torrent and download traffic is encrypted
• No port forwarding needed: VPN eliminates the need to open ports on your router
• ISP privacy: Your ISP can't see what you download or access on your NAS

Synology DSM has built-in VPN Server and VPN Client packages:

As VPN Server (access your NAS remotely)

1. Install "VPN Server" from Package Center
2. Enable OpenVPN or L2TP protocol
3. Export the configuration file
4. Import on your phone/laptop to connect remotely

As VPN Client (protect NAS traffic)

1. Install "VPN Client" from Package Center
2. Add your VPN provider's OpenVPN configuration
3. Enter credentials
4. Enable auto-reconnect
5. Route specific apps through VPN (Download Station)

QNAP QTS has similar capabilities:

1. Install QVPN Service from App Center
2. Configure as VPN Client with your provider's OpenVPN config
3. Enable kill switch (block traffic if VPN drops)
4. Route Download Station through VPN

For maximum flexibility, run VPN in a Docker container:

• gluetun — Popular Docker container that routes other containers' traffic through VPN
• Works on any NAS that supports Docker (Synology, QNAP, TrueNAS)
• Container-level kill switch
• Supports WireGuard and OpenVPN

1. NordVPN — Extensive OpenVPN config files, fast speeds, 6,400+ servers
2. Proton VPN — Open-source, port forwarding (useful for NAS), WireGuard configs
3. Mullvad — WireGuard configs, privacy-focused, flat pricing
