    I try some tests based on your description, and I think I got a solution. Try to use host_vars

    This is a playbook:

    ---
- name: Test for lemmy
  hosts: your_hosts
  vars:
    networks:
      ext:
        ipv4: "127.0.0.1"
  tasks:
    - name: Use template
      ansible.builtin.template:
        src: test.j2
        dest: "/etc/iptables/rules.v4"
        owner: root
        group: root
        mode: "0644"

    This is a template file test.j2:

    {% for rule in rules %}
{{ rule }}
{% endfor %}

    This is a host2.yml file in a host_vars directory:

    ---
rules:
  - "-A INPUT -p tcp -s {{ networks['ext']['ipv4'] }} --dport 6000 -j ACCEPT"

    For another hosts you can create separate host files with variable rules.
