1. Help - Win98/2000 and CIDR

Hi all,

I really need some help. I'm trying to configure a client's workstations to
use a SDSL line via a Lucent DSL Router. The client has been assigned a /26
network starting at 63.22.51.64 . My problem is that when I try to configure
devices with addresses 63.22.51.71 and above they are unable to see beyond
the router. The device I configured as 63.22.51.71 can't even see
63.22.51.65. I'm using the same netmask for all of the workstations
(255.255.255.192).  I was told by the DSL provider that the contiguous
addresses up to 63.22.51.126 were usable? Is that correct? No further
subnetting is required as the small LAN only has 40 workstations, correct?

Examples:
Router  ip= 63.22.51.65   netmask=255.255.255.192
Mail Server ip=63.22.51.66  netmask=255.255.255.192  - sees router and
beyond
WStations ip=63.22.51.67 to 63.22.51.70 with netmask=255.255.255.192 see
router and beyond
WStation ip=63.22.51.71 netmask=255.255.255.192 - doesn't see router

I've tried this with addresses up to 63.22.51.74 with no luck getting
outside the router. Are there issues regarding address boundaries that I
should be aware of here? If so, can anyone tell me the boundaries that I
need to 'jump' over?
Or, should I be using another netmask for the devices above 63.22.51.70? If
so, how will they be able to see the router in order to get out to the
internet?

  Thanks in advance for any help. It's greatly appreciated.
