Create container (without starting it) and connect it to multiple networks.
E.g. start the docker compose without the connector container, connect the container to the host network, and the created docker compose network, then start it and see what happens.

[mStirner]

Put container on host network, use exposed frontend port. The container works as reverse proxy.
