Ahir em vaig passar tot el dia per entendre les noves polítiques de
filtrat del kernel 2.4. Així doncs, he decidit fer-ne un resum, pq quan
se m’oblidi ho pugui recordar ràpidament.

El resum esta al SDMS en un fitxer que es diu netfilter-nat.txt, les
keywords, per trobar ràpidament el document són: netfilter nat

  1. gShield is an aggressive, modular firewall script for iptables which features
    easy configuration through a BSD-style configuration file, optional NAT
    support, TCP-wrapper-like functionality for service access, port forwarding,
    routable protection, DMZ support, user-defined open ports, transparent proxy
    support, and more.

  2. La URL del programa és: http://www.kurd.nu/monmotha/index.php
    MonMotha’s IPTables firewall is a simple shell script written in BASH. It has
    no extra subs or functions that I define, it’s just run from top to bottom.
    Hopefully this will make it fairly easy to work with. The firewall attempts to
    make setting up a firewall on a linux system running a 2.4 Linux kernel as easy
    or easier than installing most other software The firewall is easily
    configurable by changing the options located after the initial comment block of
    the script to the desired options. Fairly sensable defaults are used in case
    someone forgets this step. Many user-oriented features such as support for
    incoming (and outgoing with the proper kernel module) active ftp, and definable
    SSH support make this firewall an excellent choice for people who want to do a
    minimum of playing and a maximum of surfing…securely. There is also no need
    to rerun the script if your IP address changes. This makes it perfect for
    dial-up users! The firewall is a self contained script (at least in it’s
    original form) and has no external configuration files, making it a simple copy
    to your bootscript directory and a possible modification to another script to
    call this. While the script was designed with a BSD-style init system
    (Slackware uses these) in mind, it should work perfectly on a system that uses
    SysV style (such as RedHat Linux).
