LUCY comes with a set of firewall rules build into linux (iptables) to restrict access from the network. The firewall config is restored on each reboot. The rules are stored in /opt/phishing/config/iptables.conf The script that reads iptables rules is located in /etc/network/if-up.d/iptables.
Using root access you can either edit the rules in the file, or change/remove the script that reads them on each reboot. To remove the currently applied iptables rules and clear the firewall table you need to run a command “iptables -F”
In LUCY > 3.2 you can set custom access control lists within the GUI.
