Configuration de serveur DHCP

You will now need to inform the connection scripts in order to be authenticated by your ISP. They must have provided you with all the necessary information.

Interface que devrait écouter le DHCP : eth0

This field holds the name of the Interface connected to the LAN. Only those computers which share the same sub-network with that address will get a response from the DHCP server.

Début de l'étendue IP : 65
Fin de l'étendue IP : 254

Those fields contain the IP addresses range allowed for client DHCP hosts. The example given is for class C sub-network. Make sure that in the range, you do not include the first IP (0 in that case) nor the last (255) which are reserved. Note that the first addresses are generally reserved for static IP hosts, while last ones are used by DHCP servers.

Intervalle de temps par défaut (21600 = 6h) 21600
Intervalle de temps maximale (43200 = 12h) 43200

The assignment of an IP to a host is always limited in time. When the client does not set the needed leasing period, the server will intervene and reassign an IP to the host each "Default time interval". However, a client's request for a specific leasing period inferior to the "Max time interval" will be honored. Otherwise, an IP will be reassigned automatically after that "Max time interval".
