The word I have is that FreeBSD cannot run two NICs on the same subnet, which is what your included config shows. So try as you may it will not work. I also tested 4.7, 5.0 and 5.1 with similar results. Here is a snippet of an email I received on this topic: Begin Well, as long as I can tell, one can't have 2 ifaces on the same subnet on FreeBSD. This seems to be regarded as a feature by the guys who have written the code. "It's arguable that it should be done any other way, since it will put questions like what interface will be used for outgoing segments to the subnet ? etc. which will require to manually assign the arp table as log as you have the rest of the nodes of the subnet connected throu some kind of switches or to still have all outgoing connections throu a preferred interface which will require a SRC (IP+MAC) addresses of the other interface and will unnecessary complicated the hole thing". So the result will be a gain in the speed of incoming segments but more load on the system. END >What am I missing? All you are missing is the fact FreeBSD cannot handle two NICs the same subnet. OpenBSD does, NetBSD does and Linux does. Regards Bob D
