I have a linux machine with two interfaces eth0 and eth1. I am interested in sending a packet to address 1.2.3.4. I want the packet to go out eth0 if it is being sent by ProcessA. I want the packet to go out eth1 if is being sent by ProcessB. Is this possible to do with iptables? I see that CONFIG_NF_IP_OWNER has the ability to identify packets by process. I don't understand how to use iptables to change the interface. Any advice cheerfully accepted, Thanks, -jon
