# IPtables example The example is written for Ansible so it contains Jinja2 brackets for things like input NIC, output NIC and other items important for a captive portal firewall configuration. Server configurations vary so it's not applicable to any situation but it might help as guidance and it's well commented. # Script examples They're also written as Ansible templates because I copy them straight from my Ansible playbooks for deploying the captive portal. But it matters less for them, no important values to keep track of, everything is argument input.
