Hotel and café Wi-Fi networks are prime interception points for anyone on the same network. A portable VPN router setup tunnels all your device traffic through an encrypted endpoint you control — here's the best software stack for building one.
Fastest throughput, lowest battery drain on portable hardware, and state-of-the-art cryptography. Every other pick in this stack depends on or benefits from WireGuard.
One-command install of a WireGuard or OpenVPN server on a Raspberry Pi or VPS. Handles key generation, client profiles, and firewall rules automatically — no manual config needed.
Best-value VPS for hosting your travel VPN — under $5/month, exceptional CPU, EU and US datacenters. Pair with PiVPN and WireGuard for a personal encrypted tunnel from anywhere.
Travel security isn't just about HTTPS. Hotel and café Wi-Fi networks are prime interception points — anyone on the same network can potentially inspect, redirect, or tamper with unencrypted traffic. A portable VPN router setup lets you tunnel all device traffic through an encrypted endpoint you control, from anywhere in the world.
The approach we recommend is a self-hosted stack: a fast VPN protocol running on a cheap virtual server, deployed with a one-command installer, and optionally paired with a Docker-based gateway for commercial VPN flexibility. Here's how each piece fits together.

Every modern travel VPN setup starts with WireGuard. It's an extremely simple yet fast VPN that utilizes state-of-the-art cryptography, aiming to be faster, simpler, leaner, and more useful than IPsec — and considerably more performant than OpenVPN.1
For travel specifically, WireGuard's minimal codebase means lower CPU overhead and less battery drain on portable hardware. The protocol uses modern elliptic-curve cryptography (Curve25519, ChaCha20, Poly1305) by default, and its lean design translates to noticeably faster throughput on constrained devices like a Raspberry Pi or low-end travel router.
WireGuard vs OpenVPN: OpenVPN remains the most compatible and widely supported open-source VPN protocol, with massive community support and high configurability.5 However, it carries significantly more overhead. For a travel setup where you're routing through a budget VPS or a pocket-sized router, WireGuard's efficiency advantage is decisive. The one scenario where OpenVPN wins: restrictive networks that block WireGuard's UDP traffic but allow OpenVPN tunneled over TCP port 443.5
Setting up a VPN server manually — generating keys, configuring firewall rules, managing client profiles — is tedious. PiVPN solves this with a simplified installation script that makes deploying WireGuard or OpenVPN on a Linux server or Raspberry Pi effortless, optimized for low-power hardware with automated configuration.2
One command gets you a working WireGuard server with sensible defaults. PiVPN handles key generation, client profile management, and firewall configuration. You can run it on a Raspberry Pi at home (if you have a static IP or dynamic DNS) or — our preference for travelers — on a cloud VPS for a reliable, always-on endpoint.
Your VPN server needs to live somewhere with a stable IP, decent bandwidth, and low latency to your travel destinations. Hetzner's CX21 cloud server is widely regarded as the best value-for-money provider in Europe and North America for self-hosting, with exceptional CPU performance and low cost per GB of RAM at under $5/month.3
Pair the Hetzner CX21 with PiVPN and WireGuard, and you have a personal encrypted endpoint with no logs, no subscription beyond the VPS cost, and full control over the configuration. EU and US datacenter locations mean you can choose a server geographically close to your travel region for minimal latency.
Self-hosted vs Commercial VPN: A self-hosted WireGuard server on Hetzner gives you a dedicated IP and full control — no provider logging policies to trust, no shared server congestion. The trade-off is that you have one exit point. If you need server hopping across dozens of countries, a commercial VPN provider makes more sense — and that's where Gluetun comes in.
Gluetun is a specialized VPN client in a thin Docker container designed to act as a gateway, allowing other containers to route their traffic through a VPN provider using WireGuard or OpenVPN.4 It features DNS-over-TLS and supports multiple VPN providers, making it ideal as a travel router's VPN client.
If you're running a travel router with Docker support (like a GL.iNet device or a mini PC), Gluetun lets you connect to a commercial VPN provider's server network while adding DNS-over-TLS for encrypted DNS resolution. This is the flexible alternative to self-hosting: you get the provider's geographically distributed exit nodes, kill-switch functionality, and DNS leak protection — all containerized and portable.
WireGuard is our default recommendation, but travel networks are unpredictable. Some older hotel networks and restrictive corporate environments block WireGuard's UDP traffic entirely. OpenVPN is the fallback: the most compatible and widely supported open-source VPN protocol, highly configurable and an industry standard with massive community support.5
OpenVPN can run over TCP port 443 — the same port as HTTPS — making it extremely difficult for restrictive networks to block without breaking normal web traffic. PiVPN supports both protocols, so you can deploy WireGuard as your primary tunnel and keep an OpenVPN configuration ready for when WireGuard gets blocked.25
Worth a mention for travelers who want security without the setup: Tailscale is a mesh VPN built on WireGuard, free for personal use, offering zero-config peer-to-peer connectivity ideal for travel scenarios where you need secure access to your home network.6
Tailscale isn't a traditional VPN router — it's a mesh overlay that connects your devices directly. It's excellent for accessing a home NAS or self-hosted services while traveling, but it doesn't give you a single encrypted exit point for all traffic the way a self-hosted WireGuard server does. Think of it as a complement, not a replacement.
The recommended setup for most frequent travelers:
This stack gives you a personal encrypted endpoint with no logs, no subscription beyond a few dollars a month, and full control — the things actually worth buying for travel security.
