Share Docker container through local network and access to it from an another host

I try to share a container through my local network, to access this container from an another machine on the same network. I have follow tihs tutorial (section "With macvlan devices") and I succeeded to share a simple web container and access from an another host.

But the container that I want to share is a little more sophisticated, because he comminicate with other containers on the host through an internal network on the host.

I try to bind my existing container created in my docker-compose but I can't access to it. Can you help me, or tell me where I'm wrong if so please ?

This is my docker-compose :

version: "2"
services:
  baseimage:
    container_name: baseimage
    image: base
    build:
      context: ./
      dockerfile: Dockerfile.base

Create an external network assign the external network and devbox network to web. Web would then be publicly accessible via the external network public ip address and communicate with the internal services using the devbox network.

Will post working example asap
