Synology VPN Server: Complete Setup Guide for Secure UK Home Networks
Published on
Setting up a Synology VPN server on your Network Attached Storage (NAS) device is an excellent way to securely access your files and services from anywhere. Whether you’re working remotely or streaming media at home, a self-hosted VPN on Synology DSM provides encrypted tunnels without relying on third-party providers. This guide walks you through the process, tailored for UK users mindful of data privacy under GDPR.
Synology NAS devices, like the DS220+ or DS920+, come with built-in support for VPN servers via the free VPN Server package. It’s straightforward, cost-effective, and gives you full control over your data.
What is a Synology VPN Server?
A Synology VPN server turns your NAS into a VPN endpoint, allowing devices to connect securely over the internet. It uses protocols like OpenVPN, L2TP/IPSec, or PPTP to create encrypted connections.
- Key benefits:
- Access home network resources remotely (files, printers, cameras).
- Bypass geo-restrictions for UK streaming services when travelling.
- Enhanced privacy without logging from commercial VPNs.
- No recurring fees after initial NAS purchase.
However, it requires port forwarding and a static IP or dynamic DNS, which introduces some security considerations compared to commercial VPNs.
Requirements for Synology VPN Server Setup
Before diving in, ensure you have:
- Synology NAS running DSM 7.0 or later.
- Admin access to DSM Control Panel.
- Router supporting port forwarding (e.g., BT Smart Hub).
- Static public IP or DDNS service (Synology offers free DDNS).
- Client devices with VPN software (built-in on Windows, macOS, iOS, Android).
Pro tip: Use a UPS for power backup to prevent disruptions.
Step-by-Step Synology VPN Server Installation
1. Install the VPN Server Package
- Log into DSM web interface (find your NAS IP via Synology Assistant).
- Open Package Center > Search for “VPN Server” > Install.
- Launch the app from the main menu.
2. Enable VPN Protocols
Synology supports multiple protocols:
- OpenVPN (recommended for security): Best encryption, works on all devices.
- L2TP/IPSec: Native support on mobiles, easier setup.
- PPTP: Avoid due to vulnerabilities.
In VPN Server > OpenVPN tab:
- Check Enable OpenVPN.
- Set UDP port (default 1194).
- Enable **Dynamic IP address” for clients.
- Export config file (.ovpn) for clients.
For L2TP/IPSec:
- Enable and set a pre-shared key (PSK).
- Note username/password from Users tab.
3. Configure Users and Permissions
- Go to User & Group in DSM Control Panel.
- Create or edit users for VPN access.
- Assign permissions to shared folders.
- In VPN Server > Privilege, grant VPN access to specific users.
4. Set Up Port Forwarding on Your Router
Access your router (e.g., 192.168.1.1):
- Forward external UDP 1194 to NAS internal IP:1194 (OpenVPN).
- For L2TP, forward UDP 500, 1701, 4500.
UK note: Check with your ISP (BT, Virgin Media) for CGNAT issues; use DDNS if dynamic IP.
5. Set Up Dynamic DNS (DDNS)
- DSM > Control Panel > External Access > DDNS.
- Add Synology’s free service (e.g., yourname.synology.me).
- Enable and verify.
Connecting to Your Synology VPN Server
OpenVPN Clients
- Download .ovpn file from Synology.
- Windows: Use OpenVPN GUI.
- macOS: Tunnelblick.
- Mobile: OpenVPN Connect app.
- Import config, enter credentials, connect using DDNS:1194.
L2TP/IPSec Clients
Built-in:
- iOS: Settings > VPN > Add L2TP > Server: DDNS, PSK, username/password.
- Android: Similar in Settings.
- Windows: Network Settings > Add VPN.
Test connection from mobile data.
Troubleshooting Common Synology VPN Issues
- Can’t connect: Check port forwarding with canyouseeme.org. Verify firewall in DSM > Control Panel > Security.
- Slow speeds: Use wired Ethernet on NAS; optimise MTU in OpenVPN settings.
- No internet on VPN: Enable Allow clients to access server’s LAN only? Toggle off; set DNS to 8.8.8.8.
- CGNAT: Contact ISP or use a commercial VPN instead.
Security Best Practices for Synology VPN
- Keep DSM and VPN Server updated.
- Use strong, unique PSKs and user passwords.
- Enable 2FA via DSM.
- Monitor logs in VPN Server > Log tab.
- Avoid exposing unnecessary ports; consider WireGuard (DSM 7.2+ beta).
