UFW

Install UWF (Uncomplicated Firewall) and create (or remove) rules.

Requirements

Debian Bullseye / Bookworm with the package python-pycurl and python-software-properties installed.

Role Variables

Set the default policy:

ufw_default_policy:
  - { direction: "incoming", policy: "deny" }

Add or remove rules:

ufw_rules_to_create: []
ufw_rules_to_delete: []

Both ufw_rules_to_create and ufw_rules_to_delete accept a list of dictionaries, like so:

ufw_rules_to_create:
  - direction: in
    from_ip: 1.2.3.4
    from_port: 5678
    interface: eth0
    proto: tcp
    rule: allow
    to_ip: 5.6.7.8
    to_port: 1234

Example Playbook

- hosts: servers
  roles:
     - role: f500.ufw
       ufw_rules_to_create:
         - { to_port: 22 }
         - { to_port: 80 }
         - { to_port: 443 }
