Traefik on nas only reach the dashboard

Traefik Traefik v3 (latest)

I'm on a NAS and try to create a way to connect my docker services at home. Cause I have no Domain I control I do not work with ssl.

At moment the only domain that work is traefik itself:

labels:
      - "traefik.enable=true"
      - "traefik.http.routers.traefik.service=traefik"
      - "traefik.http.routers.traefik.rule=Host(`traefik.l.myhome`)"
      - "traefik.http.services.traefik.loadbalancer.server.port=8080"
      - "traefik.docker.network=traefik"

If I do it the same for other docker container and try to open their domain I only get a bad gateway error.
If on portainer and I go into container cli, I could ping their ip adress from the traefik network.

same bad gateway if I try to connect the synology config page

dynamic_conf.yml

http:
  routers:
    nas:
      rule: "Host(`synology.l.myhome`)"
      service: nas
  services:
    nas:
      loadBalancer:
        servers:
          - url: http://192.168.99.14
          - port: 5000

If on portainer and I go into container cli, I could not ping this ip adress.

Share you full Traefik static and dynamic config, and Docker compose file(s) if used.

Enable Traefik debug log (doc) and Traefik access log in JSON format (doc).

Clearly describe which network connections work and which do not (using ping).
