Comment:
drop historic information about modem/ISDN support, undocumented anyway.

  The reason that there can only be one main server in each school network is that the main server provides DHCP, and there can be only one machine doing so in each network. It is possible to move services from the main server to other machines by setting up the service on another machine, and subsequently updating the DNS configuration, pointing the DNS alias for that service to the right computer.
  
  In order to simplify the standard setup of Skolelinux, the Internet connection runs over a separate router, called gateway. See the [[https://wiki.debian.org/DebianEdu/Documentation/Buster/Requirements#Internet_router|Internet router]] chapter for details how to set up such a gateway if it isn't possible to configure an existing one like needed. 
- 
- It is possible to set up Debian with both a modem and an ISDN connection; however, no attempt is made to make such a setup work out of the box for Skolelinux (the setup needed to adjust the default situation to this should be documented separately).
