Problema com Marcação de pacotes iptables

Boa Tarde galera, sou novo no VoL, mas já li bastante conteúdo daqui!

Minha duvida é a seguinte:
Estou configurando um firewall Squid/iptables do zero e recentemente me propus a implantar um sistema de balanceamento e Failover.
estou seguindo o Artigo abaixo muito bom por sinal:
http://www.vivaolinux.com.br/artigo/Balanceamento-de-links-+-redundancia-+-acesso-remoto-+-sites-de-...

meu firewall esta distribuido da seguinte maneira:
eth0 iface interna
eth1 iface externa link dedicado refere-se a tabela 1 na marcação
eth2 iface externa link adsl refere-se a tabela 2 na marcação


Para não ter problemas com sites seguros, utilizo a marcação do iptables.
criei as tabelas em /etc/iproute2/rt_tables

criei as marcações pelo ip rule na seguinte linha
ip rule add fwmark 1 lookup 1 prio 1
ip rule add fwmark 2 lookup 2 prio 1

apliquei a regra a baixo no iptables para marcar os pacotes com as portas 80 (http) 443 (https) 25 (SMTP) 110 (POP3) 53 (DNS).

iptables -I PREROUTING -t mangle -i eth0 -s 192.168.0.0/24 -d 0/0 -p tcp -m multiport --dports 110,23,25 -j MARK --set-mark 1
iptables -I PREROUTING -t mangle -i eth0 -s 192.168.0.0/24 -d 0/0 -p tcp -m multiport --dports 80,443,53 -j MARK --set-mark 1

porém quando abro o iptraf ainda consigo ver trafego pela interface eth2.

Agradeço muito se alguém puder me ajudar, já procurei em todo canto.

E ai companheiro

Eu tenho uma estrutura parecida em produção apos marcar o pacote pelo firewall na hora do roteamento creio que seria assim a regra

ip rule add fwmark 2 table "NOME_TABELA"


você ta colocando numero

ip rule add fwmark 1 lookup 1 prio 1

Obrigado pela atenção amigo, já tentei com o nome creio que não seja esse o problema vou postar o meu script talvez facilite a ajuda.

Desculpe a demora é que o script esta separado em dois.

Bom na duvida vou postar algumas regras da minha estrutura


Lembre-se de na configuração do arquivo /etc/network/interfaces "eu não coloquei gateway na configuração"

Obrigado vou verificar e marco o topico.
