You don't need to expose ports to reach your NAS remotely. We compared five VPN approaches — from zero-config mesh to full self-hosted — and picked the best for every type of NAS owner.
WireGuard-based mesh VPN with zero-config NAT traversal and a generous free tier — install it and your NAS is reachable from anywhere without port forwarding.
The fastest modern VPN protocol with total control over keys and infrastructure — ideal for advanced users who want no third-party dependency.
Layer-2 overlay makes your remote NAS appear on the same local network — perfect for Synology/QNAP setups needing LAN-broadcast protocols.
The moment you forward a port on your router to expose a Synology, QNAP, or TrueNAS box to the internet, you've painted a target on it. Botnets scan for open NAS dashboards around the clock, and even a strong password won't protect you from zero-day exploits in the NAS firmware itself. The safer path is a virtual private network — an encrypted tunnel that lets your devices reach the NAS without opening anything to the public.
The good news: you no longer need to be a network engineer to set this up. Modern mesh VPNs handle NAT traversal automatically, self-hosted WireGuard is faster than ever, and zero-trust solutions bring enterprise-grade access control to home setups. The best choice depends on where you fall on the convenience-to-control spectrum.
We compared five approaches across the criteria that matter most for NAS owners:
Tailscale is a mesh VPN built on WireGuard that requires zero configuration. Install the client on your NAS (or a device on the same network) and on your remote laptop or phone, log in with the same account, and every device can see every other device — no port forwarding, no static IPs, no firewall rules.1
For NAS owners, this is the path of least resistance. Tailscale's NAT traversal is excellent, meaning it works even behind carrier-grade NAT where traditional VPNs fail. The free tier covers up to 100 devices for personal use, which is far more than any home setup needs.1 If you run a Synology NAS, there's a community package available; TrueNAS users can install it in a jail or container.
The trade-off is that Tailscale's coordination server is managed by the company. Your encryption keys are yours, but the mesh routing metadata passes through their infrastructure. For most people, that's an acceptable trade for the convenience. If it's not, look at the self-hosted options below.
WireGuard is the protocol underneath Tailscale, but you can run it directly — no third party involved. It's an extremely simple yet fast and modern VPN protocol using state-of-the-art cryptography, and it runs on virtually every platform: Linux, Windows, macOS, BSD, Android, and iOS.2
The appeal here is total control. You generate your own keys, configure your own endpoints, and nothing routes through anyone else's servers. WireGuard's codebase is small enough to audit in an afternoon, and its performance is the benchmark against which every other VPN protocol is measured.2
The cost is setup complexity. You'll need to configure keys, manage peer lists, and handle NAT traversal yourself — which typically means running a WireGuard server on a device with a public IP or setting up a relay. For advanced users who already manage their own infrastructure, this is the gold standard. For everyone else, Tailscale wraps the same protocol in a layer of convenience.
ZeroTier takes a different approach: it creates a Layer-2 overlay network, meaning your remote devices appear to be on the same Ethernet segment as your NAS.3 This matters for NAS setups that rely on LAN-broadcast protocols — Bonjour, mDNS, SMB discovery, or any service that expects devices to be on the same subnet.
For Synology and QNAP owners who want their remote machine to behave exactly as if it were plugged into the home switch, ZeroTier is the most seamless option. It's free for up to 25 devices, which covers most home and small-business setups.3 The peer-to-peer mesh means traffic flows directly between devices when possible, with a relay fallback for tricky NAT situations.
The Layer-2 model does add a small amount of overhead compared to WireGuard's Layer-3 tunneling, but in practice the difference is negligible for file access and media streaming. If you've ever struggled with a mesh VPN where your NAS "isn't on the same network," ZeroTier solves that problem directly.
PiVPN is a single installation script that deploys WireGuard or OpenVPN on a Raspberry Pi or any Debian-based Linux box sitting next to your NAS.4 If you already have a Pi on your network (and many NAS owners do), this is the fastest way to stand up your own VPN server without touching WireGuard's configuration files by hand.
The script handles key generation, firewall rules, and client profile creation. You run it once, add clients with a one-word command, and scan the generated QR codes on your phone or import profiles into your laptop's VPN client.4 It's community-driven and completely free.
PiVPN still requires port forwarding on your router (one port, to the Pi), so it doesn't solve the NAT-traversal problem the way Tailscale or ZeroTier do. But if you have a public IP or a dynamic DNS setup and want full self-hosted control without the manual WireGuard learning curve, PiVPN is the sweet spot.
Twingate replaces the traditional VPN model with zero-trust network access. There are no open ports — the Twingate connector sits inside your network and establishes an outbound connection to Twingate's infrastructure, so your network remains invisible to the internet.5 Access is identity-based: you define which users can reach which resources, and authentication happens per-connection rather than granting blanket network access.
For NAS owners who share access with family members, contractors, or a small team, this is a meaningful upgrade over a flat VPN. You can grant someone access to the NAS file share without giving them a route to your router's admin panel. The free tier supports up to 5 users and 5 resources, which is enough for a household or very small office.5
The managed model means you're trusting Twingate with access policy, and the free tier has limits that a growing small business will eventually outgrow. But for users who want enterprise-grade access control without tuning VPN protocols, it's the most polished option here.
| Criteria | Tailscale | WireGuard | ZeroTier | PiVPN | Twingate |
|---|---|---|---|---|---|
| Port forwarding needed? | No | Yes (or relay) | No | Yes | No |
| Setup difficulty | Very easy | Hard | Easy | Easy (if you have a Pi) | Easy |
| Self-hosted? | No (coordination server) | Yes |
Tailscale and ZeroTier win on ease and NAT traversal — neither requires you to touch your router. WireGuard and PiVPN win on control and independence from third parties. Twingate wins on access policy and security model. On raw speed, WireGuard's protocol core is the fastest across all options, though the differences are small in practice.2
All five are free to start with, so there's no cost to trying more than one. The things actually worth buying here are time and peace of mind — whichever option gets your NAS off the public internet fastest is the right one for you.
