Description Don Beusee 1999-06-18 09:59:31 UTC

I have a DSL service (Covad) which requires me to set the
subnet mask to a subnet having only 5 hosts:
gateway    : 152.68.6.249
subnet mask: 152.68.6.248
IP's to use: 152.68.6.<250-254>
Unfortunately Linux does not let me set the subnet mask to
the above value.  Solaris and Windows 98 do, and it works
fine on those OS's.

Please try a subnet mask of 255.255.255.248
152.68.6.248 is not a valid subnet mask.
