Ae segue tambem um pequeno script de firewall
-----------------------------------------------------------------------------------------------------------------------------------
#### Ativa o roteamento
echo "1" > /proc/sys/net/ipv4/ip_forward
#### Limpa as regras
iptables -F
iptables -X
iptables -F -t nat
iptables -X -t nat
iptables -F -t filter
iptables -X -t filter
#### Mascara a conexao
iptables -t nat -A POSTROUTING -s 10.1.1.0/24 -d 0/0 -j MASQUERADE
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -d 0/0 -j MASQUERADE
#### Proxy Transparente - Redireciona todo o trafego da porta 80 pra porta do squid
iptables -t nat -A PREROUTING -s 10.1.1.0/24 -p tcp --dport 80 -j REDIRECT --to-port 3128
iptables -t nat -A PREROUTING -s 192.168.0.0/24 -p tcp --dport 80 -j REDIRECT --to-port 3128

Ae não tive ainda a oportunidade de estar testando o squid 2.6, testa ai então as configurações e depois avisa a gente pra ve se deu certo
