captive.whump.shanti-portal/docs/examples/iptables

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.
