Assume a box with 2 NIC's connected to 2 networks - 10.0.0.0/24 and 192.168.168.0/24. What determines the source IP address of a packet sent from this box to either of its attached networks? Is it eth0? How can I influence the source address of a packet destined for either network to show its source to be from that network? i.e. All packets originating on this box going to the 192.168.168.0 network show it coming from that network, and all packets destined for the 10.0.0.0 network show it coming from that network? The reason I ask is because I always assumed the packet would have a source address closest to the destination. I discovered however that this is not the case.
