Hello Managers and Gurus,

  I'll need to redefine our network to work with a subnet-mask, We need
to expand our net to another building. The problem is I never did it before.

  I'm planning to brake our 254 IPs on 8 subnets with 30 IPs each, planing
future expansions, it will give me a subnet like 255.255.255.224 right ?

  But my probs. are: We have an DECbrouter 90T1, with is our Internet
gateway. it's configured with the IP 200.250.8.30... when I tried to change
the mask of them to use 3 bits (224) it dont permit (error Bad mask), but if
I change the IP to 200.250.8.33 it works. But with "33" the router are
sent to another subnet (all my hosts are under the address 30).

  What I can do ??? and another point, on the second router (wich will
link to the other building) I can make something like this:

  subnet mask: 255.255.255.224 another hosts
                                      | | | |
  Internet ---> router <------------+-+-+-+-+----> 200.250.8.4
             200.250.8.30 | router
                                 Alpha Server 200.250.8.65
                                 200.250.8.1 |
                                                       |
                                                   200.250.8.66
                                                     router
                                                       |
                             subnet 200.250.8.64 <-----+

   Will this works ??? I need to had a good chance of success before try
it!!, I will down all the network to reconfigure IPs and my users dont
like to stay without our computers :)

   Another question: Where I can found the old mails (or at least the
summaries) of this list ?

                                 Thanks in advance,

                                               Antonio.

PS.: I will SUMMARIZE.
PS2: sorry for my poor english :)
