roteamento internet debian etch

["Márcio Pedroso" <sarrafocapoeira@gmail.com>]

eu estou usando o debian etch como roteador de internet, fiz assim.... 
criei um arquivo com permição de execução dentro de /usr/local/sbin/regras
#!/bin/bash
iptables = /usr/sbin/iptables
sysctl = /sbin/sysctl
echo

echo -e "\n\n Exencutando Regras.\n"
#regras de roteamento de internet
iptables -F
iptables -F INPUT
iptables -F OUTPUT
iptables -F POSTROUTING -t nat
iptables -F PREROUTING -t nat
iptables -P FORWARD ACCEPT
iptables -t nat -A POSTROUTING -j MASQUERADE
sysctl -w net.ipv4.ip_forward=1

e no /etc/init.d/bootmisc.sh adicionei a linha 
./usr/local/sbin/regras
#!/bin/sh

mas ele nao consegue rotear o sinal...
eles "pingam" um no outro sem perda de pacotes... executei as regras de iptables diretamente no terminal e o problema persiste..
