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. H.J. 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.
