I need to route all the outgoing DNS traffic of the system via eth1 interface. Pls let me know if below IPTABLES rules is proper way ? > Hi, the "iptables -A FORWARD" authorizes or denies traffic only. There is no impact on the routing of your traffic. You want to perform a "policy based routing". Your policy is "All UDP/53 traffic must use eth1 as outgoing interface". To achieve this, have a look to iproute and the LARTC guide http://lartc.org/howto/ http://lartc.linuxsystems.it/index.php/Main_Page Regards, Yann. -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
