Hi,

I know this is not specifically about Unraid, but it is related. How does Gluetun actually work?

I have set up a container stack in Unraid that includes Gluetun. For the other container in the same stack, I have specified the network like this: network_mode: service:gluetun.

From what I understand, Gluetun establishes a VPN connection to the VPN provider, gets a different public IP address, and then routes the traffic from all other containers in the stack that are configured to use Gluetun through that connection. Is that correct?

This is one of my stacks:

version: "3"
services:
  gluetun:
    image: qmcgaw/gluetun
    cap_add:
      - NET_ADMIN
    devices:
      - /dev/net/tun:/dev/net/tun
    environment:
      - VPN_SERVICE_PROVIDER=[VPN provider]
      - VPN_TYPE=wireguard
      - WIREGUARD_PRIVATE_KEY=[Password]
      - WIREGUARD_ADDRESSES=[IP]
      - SERVER_COUNTRIES=[Country]
      - SERVER_CITIES=[City]
      - SERVER_CONNECTION_PROTOCOL=ipv4
      - HTTP_CONTROL_SERVER_AUTH=basic
      - HTTP_CONTROL_SERVER_USERNAME=vpn
      - HTTP_CONTROL_SERVER_PASSWORD=[Password]
    ports:
      - 8012:8012
      - 9526:9526
      - 8666:8666
      - 7232:7232
    volumes:
      - /mnt/user/appdata/gluetun:/gluetun
    healthcheck:
      test: ["CMD-SHELL", "wget -qO- https://test.net/ | grep -q 'You are connected'"]
      interval: 10s
      timeout: 5s
      retries: 30
      start_period: 20s
    restart: unless-stopped

  qbittorrent:
    image: lscr.io/linuxserver/qbittorrent:latest
    container_name: qbittorrent
    network_mode: service:gluetun
    depends_on:
      gluetun:
        condition: service_healthy
    environment:
      - PUID=252
      - PGID=123
      - TZ=[]
      - WEBUI_PORT=8034
    volumes:
      - /mnt/user/appdata/qbittorrent:/config
      - /mnt/user/downloads:/downloads
    restart: unless-stopped
networks: {}

Is this the correct way to set it up, and how can I verify that the container is actually using the VPN?

Will this also work as a secure kill switch if the VPN connection goes down?

Regards
