Looking to route Docker container traffic through your own VPN? We compare four self-hosted solutions — WireGuard, Headscale, Gluetun, and OpenVPN — across performance, setup complexity, and network topology to help you pick the right one for your homelab or production setup.
If you run Docker containers at home — whether it's a media server, a home automation hub, or a development environment — you've probably wondered how to connect to them securely from outside your network. Or maybe you want certain containers to route their traffic through a VPN provider without exposing your whole machine. A self-hosted VPN is the answer.
The challenge is picking the right one. The landscape breaks down into a few distinct categories: simple high-performance tunnels, mesh networks for multi-host setups, container-specific outbound gateways, and the old reliable for restrictive networks. Here's how they compare.
| Feature | WireGuard | Headscale | Gluetun | OpenVPN |
|---|---|---|---|---|
| Performance | ~4 Gbps+ | ~2-3 Gbps | Depends on provider | ~200-600 Mbps |
| Setup Complexity | Low | Medium | Low | Medium-High |
| Topology | Point-to-point | Mesh (via Tailscale) | Outbound gateway | Hub-and-spoke |
WireGuard is the modern standard for VPN performance. Its kernel-level implementation in Linux delivers throughput that can saturate gigabit connections with ease — benchmarks show it outperforming OpenVPN by 5-10x in most scenarios.1 In Docker, you can run it as a lightweight sidecar or standalone container with minimal configuration.
When to pick it: You need a fast, simple tunnel to access your Docker services from a few remote clients (phone, laptop, another server). You're comfortable with a few config files and don't need automatic mesh routing.
Headscale is an open-source implementation of Tailscale's control server. It gives you a WireGuard-based mesh network where every node can talk to every other node directly, with automatic NAT traversal using DERP relays when needed.1 This is a game-changer if you have Docker hosts spread across different networks (home, cloud VPS, friend's server).
When to pick it: You have multiple Docker hosts in different locations and want them to communicate as if they were on the same LAN. The mesh topology means you don't need to configure port forwarding or maintain a central VPN server.
Gluetun is not a VPN server — it's a VPN client that runs as a Docker container and lets other containers route their outbound traffic through it. You connect it to a commercial VPN provider (Mullvad, NordVPN, ProtonVPN, etc.), then use Docker's network_mode: "service:gluetun" to route specific containers through that tunnel.1
When to pick it: You want only certain containers (like qBittorrent or Sonarr) to appear to come from a VPN IP, while leaving your other containers on your regular connection. It's the cleanest way to isolate VPN traffic in Docker.
OpenVPN is the old guard. It's slower than WireGuard — typically topping out around 200-600 Mbps depending on CPU and cipher choice — but it runs over TCP port 443, which means it works through almost any firewall or corporate proxy that blocks everything else.1
When to pick it: You're connecting from a restrictive network (hotel, office, certain countries) that blocks UDP or non-standard ports. OpenVPN over TCP 443 will get through where WireGuard won't. It's also the safest bet if you need to support legacy clients.
You can also combine them. A common pattern: use Gluetun for outbound container traffic, and run WireGuard or Headscale alongside it for inbound remote access. They don't conflict.
