FireHOL role

Setup FireHOL ip blacklists.

Usage

Configure the role.

firehol_enabled: true # default: false
firehol_data_dir: /usr/share/firehol # default: /etc/firehol

And include it in your playbook.

- hosts: firehol
  roles:
  - role: firehol

Check if host ip is in applied blacklist.

sudo iptables -S FIREHOL_BLACKLIST | grep "$(hostname -I | awk '{print $1}')"
sudo iptables -S FIREHOL_BLACKLIST | grep "216.21.8.0"

Check if iptable rules work.

IP="216.21.8.0/22"
sudo iptables -C FIREHOL_BLACKLIST -s $IP -j DROP && echo "Blocked" || echo "Not blocked"

If you get the following error:

iptables v1.8.4 (nf_tables): Chain 'FIREHOL_BLACKLIST' does not exist
Try `iptables -h' or 'iptables --help' for more information.

You have to create the table manually

sudo iptables -N FIREHOL_BLACKLIST
