Imagine the following situation: NIC0 10.0.0.1/24 NIC1 10.0.0.2/24 The kernel gets a packet from 10.0.0.3. Where should the reply would be send from? NIC0 or NIC1? Situation #2 NIC0 10.0.0.1/24 NIC1 10.0.0.2/24 NIC2 192.168.0.1/24 The kernel gets a packet for 10.0.0.3. Where this packet should be forwarded to? So, FreeBSD does not accept such IP configurations, to keep things sane. Other operating systems accept such configurations, but you have to be careful and you have to know what you are doing, in order to prevent self foot-shooting. Of course there are valid ways to achieve the same results without the foot-shooting factor. Using aliases with /32 mask is one. What's wrong with IP_alias/32?
