Description

This module allows you to handle firewall rules using hiera declarations

Setup

Beginning with firewallmanager

Basically all you need to start using it is to include the firewall manager class

include 'firewallmanager'

Usage

Basically you will define the open ports you need on hiera files like this

Usual example

frwRule::ports:
  '10058':
    'tcp': 'allow'
  '54663':
    'tcp': 'allow'
    'udp': 'allow'
  '54664':
    'tcp': 'allow'
  '54953':
    'tcp': 'allow'

A more advanced rule set is also supported

frwRule::rules:
            -
              port: '8080'
              protocol: 'tcp'
              action: 'accept'
              source: '10.252.7.0'
              sourcemask: '24'
              destination: '0.0.0.0'
              destinationmask: '0'
            -
              port: '80'
              protocol: 'tcp'
              action: 'accept'
              source: '10.252.7.0'
              sourcemask: '24'
              destination: '0.0.0.0'
              destinationmask: '0'
