d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	26 The firewall module lets you manage firewall rules with Puppet.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	29
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	30 PuppetLabs' firewall module introduces the `firewall` resource, which is used to manage and configure firewall rules from within the Puppet DSL. This module offers support for iptables and ip6tables. The module also introduces the `firewallchain` resource, which allows you to manage chains or firewall lists and ebtables for bridging support. At the moment, only iptables and ip6tables chains are supported.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	32 The firewall module acts on your running firewall, making immediate changes as the catalog executes. Defining default pre and post rules allows you to provide global defaults for your hosts before and after any custom rules. Defining `pre` and `post` rules is also necessary to help you avoid locking yourself out of your own boxes when Puppet runs.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	45
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	46 Firewall uses Ruby-based providers, so you must enable [pluginsync](http://docs.puppetlabs.com/guides/plugins_in_modules.html#enabling-pluginsync).

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	48 ### Beginning with firewall
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	49
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	50 In the following two sections, you create new classes and then create firewall rules related to those classes. These steps are optional but provide a framework for firewall rules, which is helpful if you’re just starting to create them.
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	51
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	52 If you already have rules in place, then you don’t need to do these two sections. However, be aware of the ordering of your firewall rules. The module will dynamically apply rules in the order they appear in the catalog, meaning a deny rule could be applied before the allow rules. This might mean the module hasn’t established some of the important connections, such as the connection to the Puppet master.
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	53
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	54 The following steps are designed to ensure that you keep your SSH and other connections, primarily your connection to your Puppet master. If you create the `pre` and `post` classes described in the first section, then you also need to create the rules described in the second section.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	56 #### Create the `my_fw::pre` and `my_fw::post` Classes
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	57
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	58 This approach employs a whitelist setup, so you can define what rules you want and everything else is ignored rather than removed.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	60 The code in this section does the following:

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	62 * The 'require' parameter in `firewall {}` ensures `my_fw::pre` is run before any other rules.
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	63 * In the `my_fw::post` class declaration, the 'before' parameter ensures `my_fw::post` is run after any other rules.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	65 The rules in the `pre` and `post` classes are fairly general. These two classes ensure that you retain connectivity and that you drop unmatched packets appropriately. The rules you define in your manifests are likely to be specific to the applications you run.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	67 1. Add the `pre` class to `my_fw/manifests/pre.pp`, and any default rules to your pre.pp file first — in the order you want them to run.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	202
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	203 There are two kinds of firewall rules you can use with firewall: default rules and application-specific rules. Default rules apply to general firewall settings, whereas application-specific rules manage firewall settings for a specific application, node, etc.
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	204
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	205 All rules employ a numbering system in the resource's title that is used for ordering. When titling your rules, make sure you prefix the rule with a number, for example, '000 accept all icmp requests'. _000_ runs first, _999_ runs last.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	207 Note: The ordering range 9000-9999 is reserved for unmanaged rules. Do not specify any firewall rules in this range.

d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	211 You can place default rules in either `my_fw::pre` or `my_fw::post`, depending on when you would like them to run. Rules placed in the `pre` class will run first, and rules in the `post` class, last.
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	212
d9352a684e62 Mass update of modules to remove deprecation warnings IBBoard <dev@ibboard.co.uk> parents: diff changeset	213 In iptables, the title of the rule is stored using the comment feature of the underlying firewall subsystem. Values must match '/^\d+[[:graph:][:space:]]+$/'.
