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.
