cookbook 'iptables', '= 2.0.0'
Installs the iptables daemon and provides resources for managing rules
cookbook 'iptables', '= 2.0.0', :supermarket
knife supermarket install iptables
knife supermarket download iptables
Installs iptables and provides a custom resource for adding and removing iptables rules
- RHEL/CentOS and derivatives
- Chef 12+
The default recipe will install iptables and provides a ruby script
/usr/sbin/rebuild-iptables) to manage rebuilding
firewall rules from files dropped off in
The custom resource drops off a template in
/etc/iptables.d after the
name parameter. The rule will get added to the local system firewall
through notifying the
rebuild-iptables script. See Examples below.
NOTE: In the 1.0 release of this cookbook the iptables_rule definition was
converted to a custom resource. This changes the behavior of disabling
iptables rules. Previously a rule could be disabled by specifying
You must now specify
recipe[iptables] to your runlist to ensure iptables is installed / running
and to ensure that the
rebuild-iptables script is on the system.
Then create use iptables_rule to add individual rules. See Examples.
Since certain chains can be used with multiple tables (e.g., PREROUTING),
you might have to include the name of the table explicitly (i.e., *nat,
*mangle, etc.), so that the
/usr/sbin/rebuild-iptables script can infer
how to assemble final ruleset file that is going to be loaded. Please note,
that unless specified otherwise, rules will be added under the filter
table by default.
To enable port 80, e.g. in an
my_httpd cookbook, create the following
# Port 80 for http -A FWR -p tcp -m tcp --dport 80 -j ACCEPT
This template would be located at:
my_httpd/templates/default/http.erb. Then within your recipe call:
iptables_rule 'http' do action :enable end
To redirect port 80 to local port 8080, e.g., in the aforementioned
cookbook, create the following template:
*nat # Redirect anything on eth0 coming to port 80 to local port 8080 -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
Please note, that we explicitly add name of the table (being *nat in this
example above) where the rules should be added.
This would most likely go in the cookbook,
my_httpd/templates/default/http_8080.erb. Then to use it in
iptables_rule 'http_8080' do action :enable end

NOTE: This release includes breaking changes to the behavior of this cookbook.
The iptables_rule definition was converted to a LWRP. This changes the behavior
of disabling iptables rules. Previously a rule could be disabled by specifying
enable false. You must now specify
action :disable. Additionally the cookbook
no longer installs the out of the box iptables rules. These were rules made assumptions
about the operating environment and should not have been installed out of the box.
This makes this recipe a library cookbook that can be better wrapped to meet the needs
or your particular environment.
- Definition converted to a LWRP to providing why-run support and
- The out of the box iptables rules are no longer installed. If you need these rules you'll need to wrap the cookbook and use the LWRP to define these same rules.
- Removed all references to the roadmap and deprecation of the cookbook. It's not going anywhere any time soon
- Use platform_family to better support Debian derivatives
- Converted file / directory modes to strings to preserve the leading 0
- Added additional RHEL derivitive distributions to the metadata
- Expanded excluded files in the gitignore and chefignore files
- Included the latest contributing documentation to match the current process
- Fixing File.exists is deprecated for File.exist
- [#14] Adds basic testing suite including Berksfile
- [#14] Adds basic integration/post-converge tests
- [#14] Adds default prefix and postfix rules to disalow traffic
- [COOK-4496] Added Amazon Linux support
- [COOK-3927] Substitute Perl version of rebuild-iptables with Ruby version
- [COOK-4411] - Add newling to iptables.snat
- [COOK-2213] - iptables disabled recipe
- [COOK-1883] - add perl package so rebuild script works
- [COOK-641] - be able to save output on rhel-family
- [COOK-655] - use a template from other cookbooks
- Current public release.
