Multiple networks for a container inside a pod

[mrepetto94]

Sorry for posting it here but no one had an answer to this problem apparently
I'm crushing my head over the way Podman does networking.

I've the following minimal Ansible playbook:

- name: Setup Media Server Pod
  hosts: localhost
  tasks:

    - name: Run Gluetun container for AirVPN
      containers.podman.podman_container:
        name: gluetun-airvpn
        image: docker.io/qmcgaw/gluetun:latest
        state: quadlet
        quadlet_dir: ~/.config/containers/systemd/
        env:

I can't make the qbitorrent container using the vpn inside the container. But If I build the container outside the pod I can. The problem is that I would like to use this container inside the pod.
