Perguntas & Respostas

Bom kara eu uso esta regra no meu arquivo de firewall

#Liberando smtp e pop3
/usr/sbin/iptables -A FORWARD -p TCP --dport 25 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p TCP --sport 25 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p UDP --dport 25 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p UDP --sport 25 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p TCP --dport 110 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p TCP --sport 110 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p UDP --dport 110 -j ACCEPT
/usr/sbin/iptables -A FORWARD -p UDP --sport 110 -j ACCEPT
e no squid as acl tem que estar com as portas 25 e 110 liberadas tb

espero ter ajudado
