FIAIF is  an  Intellegent  Firewall. The Goal of  FIAIF  is to
provide  a  highly  customizable  script  for  setting  up  an
iptables based firewall.

Unlike  many  other scripts,  FIAIF  can  be truly  customized
allowing multiple  interfaces (or  rather zones). There  is no
limit  on  the number  of  zones.  All configuration  is  done
through configuration files. No  need to understand the script
behind it all.

The script makes heavy use  of state-full firewalling, and all
RELATED and ESTABLISHED packets are accepted on all chains. If
you which  to block  something out,  do not  accept it  in the
first place.

The script is written in BASH.  Though this is not the optimal
program to use, it means that you do not need to install extra
interpreters  on your  firewall.  This allows  you  to have  a
minimalistic installation on your firewall.

Install this package if your machine is ever on the internet.
