“VPN on Raspberry Pi” actually means two different projects, and mixing them up wastes a weekend. You can either turn the Pi into your own VPN server so you can securely reach your home network from anywhere, or run a commercial VPN client on the Pi so every device on your home network routes through a paid VPN service. This guide covers both, with the tradeoffs made explicit so you pick the right one first.
Option A: Self-Hosted VPN Server (PiVPN)
This turns your Pi into a private gateway back into your own home network — useful for reaching your NAS, security cameras, or home lab securely from a coffee shop or hotel Wi-Fi. It does not give you a new public IP address to browse from or unblock geo-restricted streaming, because the traffic still exits through your home internet connection.
What You Need
- A Raspberry Pi 4 or 5 (2GB RAM is enough for VPN duty alone) — a basic Raspberry Pi starter kit with case, power supply, and a 32GB+ microSD card covers everything, around $70-90 depending on the model.
- Raspberry Pi OS Lite (no desktop needed) flashed via Raspberry Pi Imager.
- Router access to set up port forwarding.
- A domain name or free Dynamic DNS hostname (DuckDNS, No-IP) if your ISP doesn’t give you a static public IP.
Installing PiVPN
PiVPN is the standard installer for this and wraps both WireGuard and OpenVPN in one guided setup:
- SSH into the Pi and run
curl -L https://install.pivpn.io | bash. - Choose WireGuard when prompted — it’s faster and simpler to manage than OpenVPN for this use case, though OpenVPN remains available if you need it for compatibility with an older client.
- Confirm a static local IP for the Pi, then enter your public IP or DDNS hostname as the endpoint.
- Leave the default port (51820/UDP for WireGuard, 1194/UDP for OpenVPN) unless you have a reason to change it.
- On your router, forward that port to the Pi’s local IP — this step trips up more people than the software install itself, since every router’s UI is different.
- Run
pivpn addto generate a client profile, thenpivpn -qrto get a QR code you can scan directly into the WireGuard mobile app.
Manage clients afterward with pivpn -l (list), pivpn -c (connection status), and pivpn revoke (remove a device).
Option B: Commercial VPN Client on the Pi
If the goal is instead to route your whole home network through a commercial VPN — for ad blocking plus VPN in one box alongside Pi-hole, or to protect devices that can’t run a VPN app themselves (smart TVs, game consoles) — most major providers publish Linux CLI tools or OpenVPN/WireGuard config files that work on Raspberry Pi OS. Setup is provider-specific: install their CLI or import their .conf file into WireGuard/OpenVPN, then configure your router to send traffic through the Pi, or set the Pi up as a network-wide gateway.
Comparison Table
| Self-Hosted (PiVPN) | Commercial VPN on Pi | |
|---|---|---|
| Purpose | Remote access to your own home network | Privacy/geo-unblocking for all home devices |
| Exit IP | Your home IP (unchanged) | Provider’s server IP (many countries) |
| Unblocks streaming | No | Depends on provider |
| Ongoing cost | Just electricity (~$1-2/mo) | Provider subscription |
| Setup difficulty | Moderate (port forwarding, DDNS) | Easy-moderate (provider config import) |
Common Mistakes
- Forgetting port forwarding. The PiVPN install completes fine even if the router step is skipped — you won’t notice it’s broken until you try connecting from outside and it times out.
- No Dynamic DNS with a non-static IP. Most residential ISPs change your public IP periodically; without DDNS your client configs silently stop connecting.
- Skipping OS updates. A VPN server is an intentionally-exposed device — run
sudo apt update && sudo apt upgraderegularly and disable password-based SSH login in favor of keys. - Expecting geo-unblocking from a self-hosted setup. Your home IP is still your home IP; this route doesn’t spoof location the way a commercial VPN’s server network does.
FAQ
Is a Raspberry Pi fast enough to run a VPN server?
Yes — WireGuard in particular is lightweight and a Pi 4 or 5 can comfortably handle typical home-broadband speeds for a handful of simultaneous connections.
Do I need a static IP from my ISP?
No, a free Dynamic DNS hostname (DuckDNS, No-IP) works fine and is what most home PiVPN setups use.
Can I run PiVPN and Pi-hole on the same device?
Yes, this is a very common combo — PiVPN’s installer even detects an existing Pi-hole and offers to route VPN clients through it for network-wide ad blocking.
WireGuard or OpenVPN?
WireGuard for most people — it’s faster, uses less CPU, and has a simpler config format. OpenVPN is worth keeping only if a specific client device doesn’t support WireGuard.
The Verdict
A Raspberry Pi makes an excellent, cheap self-hosted VPN server for reaching your own home network securely — PiVPN gets a working WireGuard server running in under 15 minutes once the router’s port forward is sorted. But it’s not a substitute for a commercial VPN if your goal is unblocking geo-restricted content or masking your location; for that, either run a commercial provider’s client on the Pi or just use their app directly on your device.
