Trying to do routing between different physical subnets that are one logical subnet is not a good thing. For the above, you would want to do bridging, not routing. 111.222.333.1 --- 111.222.333.2 (no IP) --- Switch Router NIC FreeBSD Box NIC |-- 111.222.333.0/24 There are other options like using a RFC1918 address space on one subnet if you really like to route. -- Crist J.
