for either IPv4 and/or IPv6 protocols. It's just a bash script depending
on procfs, sysfs and iptables, ip commands.
Often a functionality of allowing and filtering packets spans multiple
chains and can not be limited to a single rule therefore this script's
approach is to combine (not necessarily multiple) rules into an easy
understandable, comprehensive name. Maybe it can be called an abstract
iptables function or call. A full firewall is then assembled by a set
of these calls like:
A new static base firewall setup can be created by simply calling make in
the source folder but be aware that once is started it
utilizes iptables immediately, meaning it changes the firewall rules of
the host it has been run on. (YOU HAVE BEEN WARNED!)
If you don't intend to use it but wanna see what it does an appropriate
environment is recommended eg. a VM to avoid interference with your running
setup. For a detailed manual page see the ipturntables.8 file.
