   >From what I found, I came up such a configuration:

   1. A 486 PC running Linux with an ethernet card.
   2. A Combinet EVERYWARE 1000 Card.
   3. IPfirewall software.

   I think that should be all I need. One thing I am not sure is how
   hard to set up the Combinet EVERYWARE 1000 Card to run PPP over it.
   BTW, We will have an ISDN Centrex with 2 B-channels. Is there
   anything I should know about my choices?

   Thanks.

I Just did this for our Elementary School. First off ... be VERY careful
with that Combinet card. Don't get it unless your ISP _guarantees_ it'll
work that way you want (which implies Combinet hardware at the ISP).

Take a look in http://whited.rvusd.k12.ca.us/technical for a view of
our installation.
