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.

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
