DHCP Server
The
DHCP Settings for the LAN Interface
page offers the
following input options:
Enable DHCP Server
checkbox activates the DHCP server on QX
gateway . With this checkbox enabled, QX gateway 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
Special Devices
table. 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 QX gateway 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 exceeds the
allowed IP address range defined by subnet mask (it could be up to 508).
WINS Server
defines a WINS server IP address for the QX gateway LAN users.
DHCP Advanced Settings link leads to the page where the advanced options of the QX gateway's DHCP server can be configured.
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 QX gateway’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 System Configuration Wizard .
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 QX
gateway’s LAN.
MAC Address
text fields require the MAC address of the device in
the QX IP PBX’s LAN.
Static IP Address
text fields require a fixed IP address of the
device in the QX gateway’s LAN.
Please Note:
If you leave this field empty, the device in the QX
gateway’s LAN will get the first available IP address from range
defined in the
DHCP Settings
page (see above).
