When I have the following situation: a box with twon nics, one 192.168.1.1, ethernet adr aa , the other 192.168.1.2 ethernet adr bb When I do an ARP request for 192.168.1.2, both respond. aa as wel as bb But if I do another request for 192.168.1.2, and I direct it to the aa NIC, it does not respond. Unless I turn on packet_forwarding (i.e. routing). Remember, ARP is not routable, or shouldn't be, yet it is treated as such. Regards, Bas
