2.5  DHCP Server Configuration

Go to the Configuration → DHCP server section in Kerio Administration Console. Open the Scopes tab to create an IP scope for hosts to which addresses will be assigned dynamically (the Add → Scope option). The following parameters must be specified to define address scopes:

Now add a reservation for the network printer. The address you reserve need not necessarily belong to the scope described above, however, it must belong to the specified network (in this example the 192.168.1.3 address is reserved). You need to know the hardware (MAC) address of the printing machine to make the reservation.

Hint

Do not make the reservation manually unless you know the MAC address of your printing machine. Run the DHCP server and connect the machine to the network. An IP address from the formerly defined scope (see above) will be assigned to the printing machine. In the list of leased addresses, mark this IP address and click on Reserve.... This opens a dialog for IP address reservation with the corresponding MAC address already predefined. Change reserved IP address to the desired one (192.168.1.3), edit the description and click on OK. Restart your printing machine. The appropriate IP address will be assigned to the printing machine by the DHCP server after the restart.

Notes:

  1. Do not enable (allow) the DHCP server unless all desired scopes and reservations are made or unless you need to determine a client's MAC address (see above).

  2. You can also use another DHCP server to detect settings of your network equipment automatically. Set the firewall computer's internal IP address (192.168.1.1) as the default gateway and DNS server in parameters for this range on the DHCP server.
