5.0 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below

The ufw module manages the uncomplicated firewall (ufw). It allows to control netfilter rules (via ufw_rule resource) and routes (via ufw_route resource) as well as to manage ufw related configuration files.

This module succeeds the original attachmentgenie-ufw module that is now deprecated.

The key improvements:

  • supports ufw route
  • supports ufw framework (after.rules, before.rules, etc)
  • supports purging unmanaged routes and rules

See limitations for the unsupported functionality.


What ufw affects

  • Ufw rule and route settings of managed nodes.
  • Configuration files (/etc/default/ufw, /etc/logrotate.d/ufw, /etc/rsyslog.d/20-ufw.conf, /etc/ufw/sysctl.conf).
  • Custom rule files (after.rules, after6.rules, before.rules, before6.rules).
  • Purges unmanaged ufw rules (if selected to purge).
  • Purges unmanaged ufw routing rules (if selected to purge).
  • Ufw package and service.

Setup requirements

The ufw module does not require any specific setup to be used.


Warning: UFW denies incoming traffic by default, so it locks out users unless provided a rule that allows remote management (ssh, etc).


class {'ufw':
  purge_unmanaged_rules  => true,
  purge_unmanaged_routes => true,
  rules                  => {
    'allow ssh connections' => {
      'action'       => 'allow',
      'to_ports_app' => 22,


Entries in the rules accept the same parameters as ufw_rule does.

Entries in the routes accept the same parameters as ufw_route does.

Addresses support both individual hosts ( and networks ( in ipv4 and ipv6 formats.

To specify a list of ports, separate them with a comma without whitespaces: 80,443

To specify a range of ports, separate them by a colon without whitespaces: 8080:8085

Check for the parameter descriptions.

ufw_rule simple usage

ufw_rule { 'allow ssh':
  action         => 'allow',
  to_ports_app   => 22,

ufw_rule { 'allow https on eth1':
  action         => 'allow',
  to_ports_app   => 443,
  interface      => 'eth1'

ufw_rule usage

ufw_rule controls regular, non-routing rules.

Important: The default action is reject for both ufw_rule and ufw_route. So the traffic is rejected if action parameter is omitted.

ufw_rule { 'allow ssh from internal networks':
  ensure         => 'present',
  action         => 'allow',
  direction      => 'in',
  interface      => undef,
  log            => undef,
  from_addr      => '',
  from_ports_app => 'any',
  to_addr        => '',
  to_ports_app   => 22,
  proto          => 'tcp',

ufw_route usage

ufw_route controls routing rules.

ufw_route { 'route vpn traffic to internal net':
  ensure         => 'present',
  action         => 'allow',
  interface_in   => 'tun0',
  interface_out  => 'eth0',
  log            => 'log',
  from_addr      => 'any',
  from_ports_app => undef,
  to_addr        => '',
  to_ports_app   => undef,
  proto          => 'any',




  • The module does not handle ordering. The rules are added in the order they provided.
  • It's possible to update a rule, but the update is performed through recreation which changes ordering.
  • Comment field is used as a rule/route name. Duplicate comments may cause unexpected behavior.
