DHCP
The DHCP page is used to adjust the DHCP settings used by the router. The DHCP settings are then assigned to any device
connecting via DHCP and assign a dynamic IP address to each device.
You can manually set the DHCP Start and End Range, the DHCP Lease Time, the default Domain Name Suffix, the Primary and
Secondary DNS Server addresses, the Primary and Secondary WINS Server addresses, as well as the NTP Server address, the
TFTP Server address and Option 150/Option 160 (VoIP options) settings.

After entering the applicable details, click “Save”.
You can also assign a particular IP address to a specific device every time that device makes a DHCP request as follows:

LAN Advanced Setup
The LAN Advanced Setup page features options to enable or disable such router features as 802.1d Spanning Tree, LLTD, IGMP
Proxy, UPnP, Router Advertisement and PPPoE Relay.
Figure 16 - LAN - Advanced Setup
NAME
DESCRIPTION
802.1d Spanning Tree
Spanning Tree Protocol is designed to prevent loops when switches and bridges are
interconnected. Use this option to enable or disable the Spanning Tree function.
LLTD
This option allows the
router to be discovered by machines using Microsoft’s Link Layer
Topology Discovery protocol.
IGMP Proxy
Enables the router to learn about multicast group membership information.
UPnP
Universal Plug and Play is set of networking protocols that allows devices to automatically
establish working configurations when connected.
Router Advertisement
Enables the router to send a multicast router advertisement from each of its multicast
interfaces, announcing the IP address of that interface. Hosts can then discover the IP
addresses of those interfaces by listening for these router advertisements.
PPPoE Relay
This enables the router to discover services offered by PPPoE Access Concentrators
reachable via Ethernet by the PPPoE Host.

WAN
The WAN page allows you to configure the optional WAN Ethernet port. Select the WAN connection type suitable for your
environment and configure parameters according to the selected connection type. In order to access this page, you must first set
Ethernet port 1 to WAN Mode from the Status screen.
DHCP (Auto config)
The 4G100W 4G LTE WiFi Router when connected to the internet will be assigned a WAN IP address from the Internet Service
Provider. Leave everything as default unless instructed by your Internet Service Provider.
STATIC (fixed IP)
If your WAN connection uses a static IP ad
dress, please select “STATIC (fixed IP)”
as the WAN Connection Type and enter the
required information in the fields provided as shown below.

respective fields.

WAN Failover Settings
The WAN Failover Backup feature of the 4G100W is designed to provide a backup Mobile broadband Internet connection in case
your primary connection should fail. To use this feature, you will need both an Ethernet WAN connection (from an xDSL
modem/ISDN/Satellite etc) and a Mobile broadband Internet WAN connection.
Figure 19 - WAN - Failover Settings
There are 4 possible WAN Failover Connection types described in the table below.
CONNECTION TYPE
DESCRIPTION
WAN Only
The WAN failover feature is completely disabled and the router uses the WAN connection as the
internet connection only. The MBB (mobile broadband) functionality is disabled.
MBB Only
The WAN failover feature is completely disabled and the router uses the MBB (mobile broadband)
connection as the internet connection only. The WAN connection will not be used.
WWAN Failover if WAN Link Down
The router uses the WAN connection as the primary connection and the MBB (mobile broadband)
connection as a backup connection. When the WAN network cable is physically unplugged the
router will start using the MBB (mobile broadband) connection.
WWAN Failover with WAN Ping
The router uses the WAN connection as the primary connection and the MBB (mobile broadband)
connection as a backup connection. When none of the specified servers respond to a ping request
the router will start using the MBB (mobile broadband) connection. The 4G100W sends ping
requests to a specified Internet Host to verify whether the (WAN) Internet connection is online and
functioning. The Fail Count specifies how many successive ping attempts can fail before the
4G100W fails over to the MBB (mobile broadband) Internet connection while the Success Count
specifies how many ping attempts must succeed in order to reset the Fail counter.
Figure 20 - WAN Failover - Connection Types
In addition, when one of the MBB failover modes are enabled the MBB (mobile broadband) connection can be set to:
Always On
–
Although the router does not use the MBB (mobile broadband) connection when the WAN connection is
available, the MBB connection will always be online as a backup connection. This allows the router to fail over quickly to
the existing MBB connection.
Dial when Required
–
The router dials the MBB (mobile broadband) connection only when it is required, that is when the
WAN connection drops out. The router will also automatically disconnect the MBB connection if the connection becomes
unnecessary, that is if the WAN connection is restored.

Routing
Static
The Static Route page is used to add or delete static routes. Static routes can be used to facilitate communication between devices
on different networks.
Figure 21 - Static Route Settings
Adding Static Routes
Enter the required values in the fields (as shown above) for route being added.
Click the “Add” button.
Please note: You must increment the “Route no” by 1 for each route in the “Route no” field otherwis
e that route will be
