# gluetun + qBittorrent — all torrent traffic routed through ProtonVPN WireGuard
# gluetun runs as the VPN container; qBittorrent shares its network namespace (same pod)
# Port forwarding via gluetun's native ProtonVPN support (VPN_PORT_FORWARDING=on)
# — gluetun handles NAT-PMP internally, exposes port at :8000/v1/openvpn/portforwarded
