(ASCEND) Ascend TNT and large IP-Pools



Hello everybody,

we have a problem with our new Ascend TNT, which we couldn't solve so
far. Perhaps someone of you has an idea.

We have two "classes" of IP-addresses - for commercial customers and
for non-commercial customers. They are handled differently in our
network and they are distinguished by their IP-addresses.

So in our TNT we want to have two IP-Pools, like this (the
IP-addresses are just examples):

pool-base-address 1 = 192.168.0.1
assign-count 1 = 1022

That would be the network 192.168.0.0/22, or in other words:
Network:   192.168.0.0
Netmask:   255.255.252.0
Broadcast: 192.168.3.255

pool-base-address 2 = 172.16.0.1
assign-count 2 = 1022

And this would be the network 172.16.0.0/22, or in other words:
Network:   172.16.0.0
Netmask:   255.255.252.0
Broadcast: 172.16.3.255

With this configuration (which works perfectly for us) it is possibly
for a dialin user to be assigned the IP-address 192.168.1.255/22 or
192.168.1.0/22 which are absolutely correct IP-addresses. But
addresses of that kind are troblesome with Windows Clients and
througout the internet because many routers/servers do not expect
addresses like those.

So I am looking for a solution to exclude those .0 and .255 addresses
from the two pools. But I didn't find anything so far. And our
reseller said he has no idea neither. :-(

Oliver.
