Gluetun Transmission Issue

Hello,

Double-check the network_mode Configuration : Ensure that the network_mode: "container:gluetun" line is correctly placed under the other docker compose file service and that there are no typos or formatting issues.

Logs for Clues : Checking logs can often provide insights into what might be going wrong. You can view the logs for both containers using:

I do not provide any support for anything to do with torrents.

Instead of Transmission you can setup another docker compose:

version: '3.8'

services:
  test-container:
    image: alpine
    container_name: test-container
    network_mode: "container:gluetun"
    command: 
      - sh
      - -c
      - |
        apk add --no-cache curl &&
        while true; do sleep 3600; done
    restart: unless-stopped

Testing External IP Address

To check the external IP address seen by the test-container (which should be the IP address provided by your VPN service via gluetun), run:

docker exec test-container curl -s http://ipecho.net/plain; echo

Testing DNS Resolution

You might also want to verify that DNS resolution is working correctly through the VPN. You can do so by resolving a well-known domain name to its IP address:

docker exec test-container nslookup google.com

or using curl to access a website:

docker exec test-container curl -sI https://www.google.com | head -n 1
