DHCP Settings for the LAN Interface 
The  DHCP Settings page provides the option of enabling a DHCP server and controlling the Bizfon user’s LAN settings. Therefore, Bizfon LAN 
users will automatically be provided with the following settings using the configured parameters: 
• 
IP addresses 
• 
NTP (corresponds to the Bizfon’s IP address) 
• 
WINS server 
• 
Nameserver (corresponds to the Bizfon’s IP address) 
• 
Domain name 
 
The DHCP Settings page offers the following input options: 
Enable DHCP Server checkbox activates the DHCP server 
on Bizfon. With this checkbox enabled, Bizfon will be able to 
assign dynamic IP addresses to the devices in its LAN. 
Give leases only to hosts listed in the static MAC 
address binding table
 checkbox enables the DHCP 
services only for the devices listed in the table below. With 
this checkbox selected, no DHCP services will be provided 
to the other devices.  
IP Address Range defines a range of IP addresses that will 
be assigned to the Bizfon LAN users. The IP range must be 
at least 6, otherwise the error message “Address Range too 
small” will prevent it from being saved. The error message 
“Address Range too large” will appear if the IP range is 
greater than 254. 
WINS Server defines a WINS server IP address for the 
Bizfon LAN users.

The Special Devices table on this page allows you to set a static IP address binding on the MAC address of the device in the Bizfon’s LAN. When 
this table is configured, the devices with defined hostnames and MAC addresses will always get the same LAN IP address from the DHCP server. 
Otherwise, devices not listed in this table will get dynamic LAN IP addresses. This table is also displayed in the 
 
Add functional button opens an Add Host page where a 
new static MAC address binding can be defined. The page 
consists of the following components: 
Hostname text field requires the hostname of the device in 
the Bizfon’s LAN. 
MAC Address text fields require the MAC address of the 
device in the Bizfon’s LAN. 
Static IP Address text fields require a fixed IP address of 
the device in the Bizfon’s LAN.

View DHCP Leases leads to the page where the DHCP leased LAN IP addresses are listed. 
The  DHCP Leased IP Addresses page includes a list of 
the leased host addresses that are part of the Bizfon’s 
LAN. For these hosts, Bizfon acts as a server supplying 
them with a unique IP address. It displays a read-only table 
describing all the leased IP hosts and their parameters. 
The table contains the following columns: 
IP address - host IP address, assigned by Bizfon.  
MAC address - host MAC address, provided by the host 
itself. 
Lease Start - date and time when the leased IP address 
has been activated. 
Lease End - date and time when the leased IP address 
has been or will be deactivated. 
Binding State – indicates the state of the DHCP lease. 
Hostname - hostname, provided by the host itself.
