Configuration of network services Figure 9.8 DHCP server — IP scopes exceptions Example: In 192.168.1.0 subnet you intend to create two scopes: from 192.168.1.10 to 192.168.1.49 and from 192.168.1.61 to 192.168.1.100. Addresses from 192.168.1.50 to 192.168.1.60 will be left free and can be used for other purposes. Create the scope from 192.168.1.10 to 192.168.1.100 and click on the Exclusions button to define the scope from 192.168.1.50 to 192.168.1.60. These addresses will not be assigned by the DHCP server. Parameters In the Address Scope dialog, basic DHCP parameters of the addresses assigned to clients can be defined: • Default Gateway — IP address of the router that will be used as the default gateway for the subnet from which IP addresses are assigned. IP address of the interface the network is connected to. Default gateway of another network would be useless (not available to clients). • DNS server — any DNS server (or more DNS servers separated with semicolons). We recommend you to use the <strong>Kerio</strong> Control’s DNS module as the primary server (first in the list) — IP address of the <strong>Kerio</strong> Control host. The DNS module can cooperate with DHCP server (see chapter 9.1) so that it will always use correct IP addresses to response to requests on local host names. • WINS server • Domain — local Internet domain. Do not specify this parameter if there is no local domain. This parameter is not used for specification of the name of Windows NT domain! Advanced Click on this button to open a dialog with a complete list of advanced parameters supported by DHCP (including the four mentioned above). Any parameter supported by DHCP can be added and its value can be set within this dialog. This dialog is also a part of the Address Scopes tab. 136
9.2 DHCP server Figure 9.9 DHCP server — DHCP settings To view configured DHCP parameters and their values within appropriate IP scopes see the right column in the Address Scope tab. Note: Simple DHCP server statistics are displayed at the right top of the Address Scope tab. Each scope is described with the following items: • total number of addresses within this scope • number and percentage proportion of leases • number and percentage proportion of free addresses Figure 9.10 DHCP server — statistics (leased and free IP addresses within the scope) Lease Reservations DHCP server enables the administrator to book an IP address for any host. Reservations can be set in both scope configuration modes, manual and automatic. The act of adding a reservation in the automatic mode does not switch to manual mode. To make the reservation click on the Add → Reservations button in the Scopes folder. 137
