DHCP
DHCP (Dynamic Host Configuration Protocol) allows clients to obtain TCP/IP configuration at
start-up from a server. This LTE Device has a built-in DHCP server capability that assigns IP
addresses and DNS servers to systems that support DHCP client capability.
DNS
DNS (Domain Name System) maps a domain name to its corresponding IP address and vice
versa. The DNS server is extremely important because without it, you must know the IP address
of a computer before you can access it. The DNS server addresses you enter when you set up
DHCP are passed to the client machines along with the assigned IP address and subnet mask.
6.1.1.2 About UPnP
How do I know if I'm using UPnP?
UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each
UPnP compatible device installed on your network will appear as a separate icon. Selecting the
icon of a UPnP device will allow you to access the information and properties of that device.
Cautions with UPnP
The automated nature of NAT traversal applications in establishing their own services and
opening firewall ports may present network security issues. Network information and
configuration may also be obtained and modified by users in some network environments.
When a UPnP device joins a network, it announces its presence with a multicast message. For
security reasons, the LTE Device allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
6.2 The LAN Setup Screen
Click
Network Setting > Home Networking
to open the
LAN Setup
screen. Use this screen to
set the Local Area Network IP address and subnet mask of your LTE Device and configure the
DNS server information that the LTE Device sends to the DHCP client devices on the LAN.

DESCRIPTION
LAN IP Setup
IP Address
Enter the LAN IP address you want to assign to your
LTE Device in dotted decimal notation, for example,
192.168.1.1 (factory default).
IP Subnet Mask
Type the subnet mask of your network in dotted
decimal notation, for example 255.255.255.0 (factory
default). Your LTE Device automatically computes the
subnet mask based on the IP address you enter, so do
not change this field unless you are instructed to do so.
DHCP Server State
DHCP
Select
Enable
to have your LTE Device assign IP
addresses, an IP default gateway and DNS servers to
LAN computers and other devices that are DHCP
clients.
If you select
Disable
, you need to manually configure
the IP addresses of the computers and other devices on
your LAN.
When DHCP is used, the following fields need to be
set.
IP Addressing Values
IP Pool Starting
Address
This field specifies the first of the contiguous addresses in
the IP address pool.
Pool Size
This field specifies the size, or count of the IP address pool.

DNS Server 1-3
Select
From ISP
if your ISP dynamically assigns DNS
server information (and the LTE Device's WAN IP address).
Select
DNS-Proxy
to have the LTE Device send its own
address to the LAN clients for them to use as the DNS server.
Select
User-Defined
if you have the IP address of a DNS
server. Enter the DNS server's IP address in the field to the
right. If you chose
User- Defined
, but leave the IP address
set to 0.0.0.0,
User-Defined
changes to
None
after you click
Apply
. If you set a second choice to
User-Defined
, and enter
the same IP address, the second
User-Defined
changes to
None
after you click
Apply
.
Select
None
if you do not want to configure DNS servers.
You must have another DHCP sever on your LAN, or else
the computers must have their DNS server addresses
manually configured. If you do not configure a DNS server,
you must know the IP address of a computer in order to
access it.

6.3 The Static DHCP Screen
This table allows you to assign IP addresses on the LAN to specific individual computers based
on their MAC Addresses.
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address
is assigned at the factory and consists of six pairs of hexadecimal characters, for example,
00:A0:C5:00:00:02.
6.3.1 Before You Begin
Find out the MAC addresses of your network devices if you intend to add them to the
Static
DHCP
screen.
Use this screen to change your LTE Device's static DHCP settings. Click
Network Setting >
Home Networking > Static DHCP
to open the following screen.

DESCRIPTION
Add new static
lease
Click this to add a new static DHCP entry.
#
This is the index number of the entry.
Status
This field displays whether the client is connected to the LTE Device.
Host Name
This field displays the client host name.
MAC Address
The MAC (Media Access Control) or Ethernet address on a LAN (Local
Area Network) is unique to your computer (six pairs of hexadecimal
notation).
A network interface card such as an Ethernet adapter has a hardwired
address that is assigned at the factory. This address follows an industry
standard that ensures no other adapter has a similar address.
IP Address
This field displays the IP address relative to the # field listed above.
Reserve
Select the check box in the heading row to automatically select all check
boxes or select the check box(es) in each entry to have the LTE Device
always assign the selected entry(ies)'s IP address(es) to the
corresponding MAC address(es) (and host name(s)). You can select up
to 128 entries in this table.

6.4 The UPnP Screen
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically
join a network, obtain an IP address, convey its capabilities and learn about other devices on the
network. In turn, a device can leave a network smoothly and automatically when it is no longer
in use.
Use the following screen to configure the UPnP settings on your LTE Device. Click
