I'm sorry, but are you saying you have something like: aaa.bbb.ccc.129/24 | | aaa.bbb.ccc.1/24 | | ----------------------------- | | | | aaa.bbb.ccc.2/? ... Because if you are your network is broken. The whole point of a netmask is to define your network. By defining your netmask as 255.255.255.0 you are saying that everything on the network aaa.bbb.ccc.0 is directly accessible, and anything that doesn't start with aaa.bbb.ccc isn't and therefore needs a gateway. Now if you deliberately have your box isolated from the rest of the network, you need different addressing. You could do it by subnetting aaa.bbb.ccc.0, but not when the two addresses or your segment are 128 apart, since the first bit you add to the netmask will put them on separate networks and therefore you'll get errors whenever you try to access the gateway.
