DHCP Settings for the VLAN Interface
DHCP Settings for the VLAN Interface
is used to establish virtual networks in the QX gateway’s LAN or to integrate the QX gateway into the corporate
network’s virtual LAN/WAN. DHCP service can be activated both on LAN or WAN interfaces. VLAN is useful in corporate companies to divide large
networks into groups and to have devices like QX gateways and IP phones in each network separated (for example, to separate networks for data and
voice transmission). Priorities may be assigned to the interfaces for packets prioritization.
With VLAN configuration, each virtual network will be characterized with a VLAN ID (tag). Packets addressed to that network will be checked towards the
ID and if the ID number defined in the incoming packets matched the corresponding network’s ID, the packets will be accepted. Otherwise, if the ID does
not match, the packets will be dropped. In the same way, if the QX IP PBX is integrated into the network that uses VLAN technology, outgoing packets
should have the ID number of the corresponding virtual network, for the remote party to accept the packets from the QX gateway.
The
DHCP Settings for the VLAN Interface
page contains a table
with all enabled VLAN interfaces created in VLAN Settings page
(see below) and the corresponding parameters (VLAN ID, IP
Address Range and WINS Server). This page contains the following
components:
Enable DHCP Server
checkbox activates the DHCP server on QX
IP PBX for VLAN. With this checkbox enabled, QX gateway will be
able to assign dynamic IP addresses to the devices in its VLAN.
Activate
functional button is used to activate DHCP service on one
of the VLAN interfaces in the list. Only one VLAN interface can
have DHCP service activated.
Edit
functional button opens a page where the corresponding
VLAN interface can be configured and controlled. This page
contains all the same components as the
page does.
link moves to the VLAN Configuration page where
virtual LAN/WAN interfaces may be created.

DNS Settings
The
DNS Settings
page provides the option of setting up a name
server for the QX gateway. It offers the following components:
The
Nameserver Assignment
radio buttons are as follows:
•
The
Dynamically by provider
selection automatically
configures the assignment of the name server address from
the provider party.
•
Fixed Nameserver address
is a manually selected name
server. The
Nameserver
text field requires the IP address
of an external name server. The
Alternative
Nameserver
text field requires the IP address of the secondary name
server. The
Alternative Nameserver
is used if the main
name server cannot be accessed.

DNS Server Settings
The
DNS Server
on the QX gateway provides the services to the hosts in the QX gateway’s LAN. With this service, QX gateway returns the correct IP
address to the requested domain name, so that any device in the LAN can be accessed by its hostname or alternative alias name.
The
DNS Server Settings
page is used to configure DNS server settings on the QX gateway and to define a list of aliases for the devices in the QX gateway’s
LAN. This page contains the following components:
