	Não, voce tem que deixar instalado o pacote iptables e ipchains. Na hora de
executar a firewall você carrega os modulos do kernel referentes ao iptables ou
ipchains.

## firewall.iptables ###
!/bin/sh
# Load Modules
echo "Loading kernel modules ..."
/sbin/depmod -a
# core netfilter module
/sbin/modprobe ip_tables
# the stateful connection tracking module
/sbin/modprobe ip_conntrack
# filter table module
/sbin/modprobe iptable_filter
# mangle table module
/sbin/modprobe iptable_mangle
# nat table module
/sbin/modprobe iptable_nat
# LOG target module
/sbin/modprobe ipt_LOG
# This is used to limit the number of packets per sec/min/hr
/sbin/modprobe ipt_limit
# masquerade target module
/sbin/modprobe ipt_MASQUERADE
# filter using owner as part of the match
/sbin/modprobe ipt_owner
# REJECT target drops the packet and returns an ICMP response.
/sbin/modprobe ipt_REJECT
# This target allows packets to be marked in the mangle table
/sbin/modprobe ipt_mark
# This target affects the TCP MSS
/sbin/modprobe ipt_tcpmss
# This match allows multiple ports instead of a single port or range
/sbin/modprobe multiport
# This match checks against the TCP flags
/sbin/modprobe ipt_state
# This match catches packets with invalid flags
/sbin/modprobe ipt_unclean
# The ftp nat module is required for non-PASV ftp support
/sbin/modprobe ip_nat_ftp
# the module for full ftp connection tracking
/sbin/modprobe ip_conntrack_ftp
# the module for full irc connection tracking
/sbin/modprobe ip_conntrack_irc

## firewall.ipchains ###
#! /bin/sh
/sbin/depmod -a
# Modulo do IPChains.
/sbin/modprobe ipchains
# Modulo para tratamento do FTP.
/sbin/modprobe ip_masq_ftp
# Modulo para tratamento do ICQ.
/sbin/modprobe ip_masq_icq
# Este msdulo suporta masquerading do RealAudio usando UDP.
/sbin/modprobe ip_masq_raudio
# Suporta o masquerading do IRC
/sbin/modprobe ip_masq_irc
