Use a new stanza like this for each new interface you want to add to an existing interface, you really don't need to be playing with route.

iface eth0:1 inet static

       address nn.nnn.18.175
       netmask 255.255.255.128
       network nn.nnn.18.128/25
       broadcast nn.nnn.18.255
       gateway nn.nnn.18.129

In the above example your chanding the routing information to an interface eth0:1 and eth0:2 that dosen't actually exist.

apartment it is.
