ericvsmith/python-iptables: Python bindings for iptables · GitHub

Python-iptables is a pythonesque wrapper around the Linux iptables/ip6tables facility. It is meant primarily for dynamic and/or complex firewalls, where rules are often updated or changed. Python-iptables makes it possible to use Python to parse or change rules without the need to spawn processes to execute an iptables command.
