Gluetun VPN Service#

What Was Established#

  • Gluetun is a lightweight Docker container acting as a dedicated VPN gateway for other containers.
  • Implements the sidecar pattern: dependent containers (e.g., qBittorrent, nzbget, prowlarr) share Gluetun’s network namespace via network_mode: "service:gluetun".
  • AirVPN selected as the provider over ProtonVPN/Mullvad due to superior port forwarding support required for P2P services.
  • Container-level VPN on the servarr VM is architecturally separate from the network-level UniFi VPN on Helms Deep (VLAN 2).

Deployment Context#

Gluetun runs on the servarr VM (192.168.1.112) as part of the Servarr Docker Compose stack at /docker/servarr/. It is configured via .env file in that directory.
