_SERIAL_,
Erros indicados referentes a tabelas inexistentes, altere seu script para algo deste jeito:
#!/bin/bash
/sbin/iptables -F # limpa todas as regras OUTPUT, INPUT
/sbin/iptables -t nat # limpa todas as regras contidas na tabela NAT
echo 1 > /proc/sys/net/ipv4/ip_forward # ativando ip_forward
/sbin/modprobe iptable_nat # inserindo o modulo do NAT
/sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # mascarando saída

Agora vai funcionar perfeitamente,

Atenciosamente,

Roberto Vianna
