[LUG.ro] Problema con iptables

[Jeremías _]

Estoy implementando un Proxy con Squid y quería agregarle una config de iptables para los puertos problemáticos
la config es la siguiente:

-----------------------------------------------------------------------------------------

iptables -F
iptables -X
iptables -Z
iptables -t nat -F
iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -t nat -P PREROUTING ACCEPT
iptables -t nat -P POSTROUTING ACCEPT
iptables -t nat -A POSTROUTING -s 192.168.14.0/24 -o eth0 -j MASQUERADE
iptables -t nat -A PREROUTING -s 192.168.14.0/24 -d ! 192.168.14.0/24 -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -A INPUT -s 192.168.14.0/24 -i eth1 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 993 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 110 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 465 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 25 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 80 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 443 -j ACCEPT

iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p tcp --dport 53 -j ACCEPT
iptables -A FORWARD -s 192.168.14.0/24 -i eth1 -p udp --dport 53 -j ACCEPT

echo 1> /proc/sys/net/ipv4/ip_forward

Ahora... Una vez ejecutado esto obtento estos errores:

Lo que supongo es que me falta algo o el apt-get install iptables iptables-dev (estoy usando Debian) no me instaló todo.
Agradecería al menos una guía. Muchas gracias

Pago cerveza en agradecimiento con picada!!!
