DHCP Server konfigurieren

Adresspool definieren:

class "virtualbox"
{
  match if binary-to-ascii(16,8,":",substring(hardware,1 ,2)) == "08:00";
}

Eigenen Adressraum für virtuelle Maschinen festlegen:

pool
{
   allow members of "virtualbox";
  range 192.168.1.200 192.168.1.220:
}

 Unbekannte Geräte ausschließen

subnet 192.168.178.0 netmask 255.255.255.0
{
option routers x.x.x.x;
range 192.168.178.50 192.168.178.150;
deny unknown-clients;

}


subnet 192.168.1.0 netmask 255.255.255.0
{
option routers x.x.x.x;
range 192.168.1.50 192.168.1.150;
option host-name = concat("intruder", binary-to-ascii(10,8,"",substring(leased-address,3,1)));
allow unknown-clients;

}
