thias/ipset — version 0.1.0 Jul 3rd 2019



Manage IP sets in the Linux kernel. Support in Red Hat Enterprise Linux has been introduced in the RHEL 6.2 kernel (run modinfo ip_set to check).

  • ipset : Main definition to create and manage IP sets.
  • ipset::iptables : Definition to manage IP set related iptables rules.
  • ipset::base : Base class for the common parts.
  • ipset::params : Base class for distribution specific parameters.

Once you have your IP sets in place, you'll want to manage iptables rules which make use of those IP sets.

This module is mostly a hack. The proper way to implementing IP sets would be to create a clean system service script which would be run before iptables.


Create a new my_blacklist IP set from a custom file :

file { '/path/to/my_blacklist.txt': content => "\n10.0.0.2\n" }
ipset { 'my_blacklist':
  from_file => '/path/to/my_blacklist.txt',

Insert an iptables REJECT rule on-the-fly which ses the my_blacklist IP set :

ipset::iptables { 'my_blacklist':
  chain   => 'INPUT',
  options => '-p tcp',
  target  => 'REJECT',

Similar, but logging 80/tcp traffic from the raw table's PREROUTING chain :

ipset::iptables { 'my_blacklist-log':
  table   => 'raw',
  chain   => 'PREROUTING',
  ipset   => 'my_blacklist',
  options => '-p tcp --dport 80',
  target  => 'LOG --log-prefix "MyList: "',
