+# UFW rules management using Ansible
+
+Since ufw is part of the community.general collection, ensure it's installed on the Ansible control machine:
+
+```sh
+ansible-galaxy collection install community.general
+```
+
+It is by default installed and enabled with ALLOW rules for SSH, HTTP and HTTPS on all images generated for this homelab.
+
+The tasks are defined in `ansible/roles/common/tasks/ufw.yml`.
+
+It is called by `ansible/playbooks/common.yml`.
