How to Access a Synology NAS Remotely Without QuickConnect

QuickConnect is handy, but it routes your traffic through Synology's own relay servers and that comes with real downsides: slower speeds, occasional downtime, and a dependency on Synology's infrastructure staying online. If you'd rather access your NAS remotely without handing your connection over to a third party, there are two solid alternatives: Synology's own VPN Server package, or a mesh VPN tool like Tailscale. This guide walks through both, plus how to map your NAS as a network drive in Windows once you're connected, how to fix the most common reasons remote access breaks, and how these methods compare to approaches for accessing other NAS brands remotely.

Expect to spend 30 to 60 minutes setting this up properly, depending on which method you choose. Tailscale is the quicker, more beginner-friendly option. Synology's VPN Server takes a bit more patience but gives you a traditional VPN setup.

What You'll Need

• A Synology NAS running a reasonably current version of DSM
• Admin access to your NAS and (for the VPN Server route) your router
• A Synology account, or a free Tailscale account
• A Windows PC for the drive mapping steps
• Your NAS's local IP address (check this in DSM under Control Panel > Network)

Step 1: Decide Which Method Suits You

Before diving in, it helps to know what you're choosing between.

1. Synology VPN Server turns your NAS into a VPN endpoint using OpenVPN or L2TP/IPSec. Once connected, your laptop behaves as if it's on your home network, so you can reach the NAS, other devices, and share folders normally. It requires port forwarding on your router, which is the fiddliest part.
2. Tailscale creates a private mesh network between your devices using WireGuard under the hood, without needing port forwarding at all. It's generally the easier and more reliable choice for most households, which is why we'd call it the best way to access your Synology NAS remotely if you don't want to deal with router configuration.

Step 2: Set Up Synology VPN Server (Option A)

If you'd rather stick with Synology's own tools, here's how to get VPN Server running.

1. Open Package Center in DSM and install VPN Server.
2. Launch VPN Server, go to OpenVPN, and tick "Enable OpenVPN server".
3. Leave the default settings unless you have a reason to change them, then click Apply.
4. Click Export Configuration to download a zip file. You'll need this later on your client device.
5. Go to Privilege in VPN Server and tick the box for each user account you want to allow VPN access.
6. On your router, forward the OpenVPN port (usually UDP 1194) to your NAS's local IP address. Every router's interface looks different, but you're looking for "Port Forwarding" or "Virtual Server" in the settings.
7. If your ISP doesn't give you a static IP, set up a DDNS hostname in DSM under Control Panel > External Access > DDNS, so you've got a consistent address to connect to from outside.
8. On your Windows PC, install an OpenVPN client (OpenVPN Connect is a common free choice), import the configuration file from step 4, and connect using your NAS username and password.

Once connected, your PC should be able to reach the NAS using its local IP address, just as if you were at home.

If you've never set up port forwarding before, or you want to compare this to other VPN approaches like WireGuard on your router, our guides on setting up WireGuard on an ASUS router and WireGuard on TP-Link and Omada routers cover similar router-side steps in more detail.

Step 3: Set Up Tailscale (Option B)

Tailscale skips the port forwarding entirely, which makes it a good fit if your router's interface is confusing or you don't have admin rights to it.

1. Create a free account at tailscale.com.
2. On your NAS, open Package Center, search for Tailscale, and install it.
3. Open the Tailscale package, click Log in, and follow the browser prompt to authorise your NAS on your Tailscale account.
4. Once authorised, your NAS appears in your Tailscale admin console with its own private address (usually something starting with 100.x.x.x).
5. On your Windows PC, download and install the Tailscale app, then log in with the same account.
6. Your PC and NAS are now on the same private network, wherever either of them physically is.

Tailscale is built on WireGuard, the same technology covered in our WireGuard config files explained piece, so if you're curious how the encryption works under the hood, that's a good follow-up read. If you're also weighing it up against NordVPN's Meshnet feature, our article on whether NordVPN can access your home network explains how that compares.

Step 4: Map the NAS as a Network Drive in Windows

Once you're connected via either method, mapping the NAS to a drive letter means you can browse your files in File Explorer just like a local disk.

1. Open File Explorer and right-click This PC in the left sidebar.
2. Select Map network drive.
3. Choose a drive letter from the dropdown (anything free will do).
4. In the folder field, type \\ followed by either your NAS's Tailscale IP address or its local IP address (if using OpenVPN), then the share name, for example \\100.101.102.103\homes.
5. Tick Reconnect at sign-in if you want this to persist.
6. Click Finish, then enter your NAS username and password when prompted.

The drive should now appear in File Explorer every time you're connected, whether you're at home or remote.

Step 5: Test the Connection From Outside Your Home Network

Don't assume it works until you've tested it properly.

1. Disconnect your PC from your home Wi-Fi and connect to mobile data or another network entirely, such as a cafe's Wi-Fi.
2. Connect via your VPN method (OpenVPN client or Tailscale).
3. Try opening the mapped drive in File Explorer, or ping the NAS's address from Command Prompt.
4. If files load and transfer normally, you're done.

Testing from a genuinely separate network matters, because some issues only show up once you're off your home router's Wi-Fi.

Common Mistakes to Avoid

• Forgetting to forward the right port, or forwarding it to the wrong local IP address if your NAS's address has changed since you last checked.
• Not setting up DDNS, which means your home IP address change breaks the connection without warning.
• Using the NAS's external DDNS address for drive mapping instead of its VPN-assigned address, which won't work once you're tunnelled in.
• Leaving default admin accounts enabled with weak passwords, which is a real security risk once you've opened any kind of remote access.
• Skipping the away-from-home test, so you only discover a misconfiguration when you actually need remote access and it fails.

Conclusion

Learning how to access your NAS remotely with Synology doesn't have to mean relying on QuickConnect. Whether you choose Synology's own VPN Server for a traditional setup or Tailscale for something quicker to configure, both get you proper, private access to your files without routing through anyone else's relay. Once it's set up and mapped as a network drive, reaching your files from anywhere becomes as routine as opening a folder on your desktop.

FAQ

Why can't I access my Synology NAS remotely?

The most common causes are an incorrect port forward, a changed local IP address on the NAS, your ISP blocking certain ports, or your router not supporting the configuration you've set up. Double-check your NAS's local IP hasn't changed, and confirm the port forward points to the right address.

Is Tailscale safe to use with a NAS?

Yes, it's built on WireGuard, which is a well-regarded, modern VPN protocol. Your traffic travels directly between your devices in most cases rather than through a third-party server, and Tailscale doesn't see your file contents.

Can I access my Synology NAS remotely from Windows without installing extra software?

Not reliably without some form of VPN or remote access tool, since Windows doesn't connect to NAS shares over the open internet by default. You need either QuickConnect, Synology's VPN Server with a client, or a tool like Tailscale running on both ends.

Do I need a static IP address for this to work?

Not necessarily. For Synology VPN Server, setting up DDNS through DSM solves the changing IP problem without needing a static address from your ISP. Tailscale doesn't need a static IP at all, since it handles device addressing itself.

Is QuickConnect actually bad, or just slower?

It's not unsafe, but it relies on Synology's relay servers when a direct connection isn't possible, which can mean slower transfer speeds and occasional interruptions if those servers have issues. For regular access to large files, a direct VPN connection is usually a better experience.

What if I don't want to touch my router settings at all?

Tailscale is your best option, since it doesn't require port forwarding. If you want to explore other router-free remote access methods too, our beginner's guide to accessing your home network remotely covers a few more approaches worth comparing.
