SYNOPSIS

ipset command name options

DESCRIPTION

FireHOL has an ipset helper. It is a wrapper around the real ipset command and is handled internally within FireHOL in such a way so that the ipset collections defined in the configuration will be activated before activating the firewall.

FireHOL is also smart enough to restore the ipsets after a reboot, before it restores the firewall, so that everything will work as seamlessly as possible.

The ipset helper has the same syntax with the real ipset command. So in FireHOL you just add the ipset statements you need, and FireHOL will do the rest.

Keep in mind that each ipset collection is either IPv4 or IPv6. In FireHOL prefix ipset with either ipv4 or ipv6 and FireHOL will choose the right IP version (there is also ipset4 and ipset6).

Also, do not add -! to ipset statements given in firehol.conf. FireHOL will batch import all ipsets and this option is not needed.

FireHOL ipset extensions

The features below are extensions of ipset that can only be used from within firehol.conf. They will not work on a terminal.

The FireHOL helper allows mass import of ipset collections from files. This is done with ipset addfile command.

The ipset addfile command will get a filename, remove all comments (anything after a # on the same line), trim any empty lines and spaces, and add all the remaining lines to ipset, as if each line of the file was run with ipset add COLLECTION_NAME IP_FROM_FILE [other options].

The syntax of the ipset addfile command is:

 ipset addfile *name* [ip|net] *filename* [*other ipset add options*]

name is the collection to add the IPs.

ip is optional and will select all the lines of the file that do not contain a /.

net is optional and will select all the lines of the file that contain a /.

filename is the filename to read. You can give absolute filenames and relative filenames (to /etc/firehol).

other ipset add options is whatever else ipset add supports, that you are willing to give for each line.

The ipset add command implemented in FireHOL also allows you to give multiple IPs separated by comma or enclosed in quotes and separated by space.

EXAMPLES

 ipv4 ipset create badguys hash:ip
 ipv4 ipset add badguys 1.2.3.4
 ipv4 ipset addfile badguys file-with-the-bad-guys-ips.txt
 ...
 ipv4 blacklist full ipset:badguys
 # example with multiple IPs
 ipv4 ipset create badguys hash:ip
 ipv4 ipset add badguys 1.2.3.4,5.6.7.8,9.10.11.12 # << comma separated
 ipv4 ipset add badguys "11.22.33.44 55.66.77.88"  # << space separated in quotes

ipsets with IP Lists for abuse, malware, attacks, proxies, anonymizers, etc can be downloaded with the contrib/update-ipsets.sh script. Information about the supported ipsets can be found at FireHOL IP Lists (http://iplists.firehol.org/)
