##Setup

###What windows_firewall affects:

  • windows firewall profile and policy.
  • windows firewall rules.

###Beginning with windows_firewall

The windows_firewall resource allows you to manage the firewall profile state and their policy.

class { 'windows_firewall': 
    profile_state => 'on',
    in_policy     => 'BlockInbound',
    out_policy    => 'AllowOutbound',
    rule_key      => 'windows_networks',
    purge_rules   => true,
}

Windows_firewall loads rules from hiera stored as hashes using key defined in 'rule_key'.

Rules can be defined using json or yaml data resource. Below is a json example:

{
  "windows_networks": {
    "Rule 1": {
      "description": "This is rule 1.",
      "remote_addresses": "10.1.2.3,10.7.8.9",
      "local_ports": "1000,1010"
    },
    "Rule 2": {
      "description": "This is rule 2.",
      "remote_addresses": "10.4.5.6-10.4.5.150",
      "local_ports": "2000-2500"
    },
    "Rule 3": {
      "description": "This is rule 3.",
      "remote_addresses": "10.1.100.1/24",
      "local_ports": "3030",
      "interfaces": "Ethernet"
    }
  }
}

###Tools

####tools\generate_rule_definitions.ps1 Powershell script for generating JSON baseline rules from pre-existing enabled advfirewall rules on a Windows system.

####hieradata\base_windows_rules.json A pre-generated json hiera resource to get started.
