ms_iptables, a simple firewall configured via json written in python

• Idea is to Configure/Apply a set of rules via iptables or other security binary and ensure that they are not applied twice.
• A contrario to another stateful firewalls (shorewall/firewalld), this wont reset your current firewall state but will try to add the rules.
• Associated docs:
  • usage
  • install
  • usage in docker context
• Attention, to provide a patch, you need to edit hacking/ms_iptables.py.in.
• Remember the companion sysctls:
  • net.ipv4.ip_forward: 1
  • net.ipv6.conf.all.forwarding: 1
