IPTEditor intends to ease the task of managing/editing iptables rules. It presents an intuitive graphical interface that organizes iptables tables as tabs of a notebook, each of which, in turn, organizes their chains in notebooks tabs. Each rules tab contains a list made up of rows (rules) or item columns ordered according to their occurrence. The items in the rows can be edited by appropriate forms, such as through dialogs for targets and criteria (modules), edit fields for network addresses, and selection boxes for actions and protocols, among others.
