Typical application
Figure 1 shows a typical use of the Motorola Cellular Gateway NC800 in a home or home office environment.
Access to the Motorola Cellular Gateway NC800 from local PCs and notebooks is either by the 802.11b/g
WLAN interface, or the Ethernet LAN interface. In this example, the PC is connected to the Ethernet LAN and
the notebook is connected via the WLAN interface.
The 802.11g WLAN interface supports an effective data transmission rate of up to 22Mbps. Note that if devices
are present on the WLAN that support 802.11b, the effective data transmission rate drops to 11 Mbps. The
Ethernet LAN interface supports data transmission rates of 10/100 Mbps.
Access from the Motorola Cellular Gateway NC800 to the Internet is achieved by using CDMA2000 EV-DO /
1xRTT technology. The Code Division Multiple Access (CDMA) antenna is placed up to six feet from the
Motorola Cellular Gateway NC800, and connects to the CDMA infrastructure via a local CDMA base station.
The CDMA2000 EV-DO supports downlink data rates of up to 2.4576 Mbps and uplink data rates of 154 kbps.

Security
The Motorola Cellular Gateway NC800 provides the following security mechanisms:
• A firewall to protect the Motorola Cellular Gateway NC800 LAN from undesired attacks over the Internet
• The capability to set up a DMZ
• Security measures to prevent eavesdropping of wireless data (including WEP / WPA-PSK encryption
and authentication)
• Multiple tunnel Virtual Private Network (VPN) pass-through operation
• Access control to configure the Motorola Cellular Gateway NC800.
The subsections below provide some introductory information regarding the security technology listed above.
More details are provided in the relevant subsections of the Detailed Motorola Cellular Gateway NC800
Configuration section as well as in the relevant Glossary entries. A full discussion of network security is beyond
the scope of this document.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 10 of 110
Note that the Setup Wizard guides you to set the Motorola Cellular Gateway NC800 up with a reasonable level
of security. If you have more stringent security requirements, the instructions in this user guide provide detailed
information on how to set up the relevant security fields.
Figure 3 illustrates the security measures provided by the Motorola Cellular Gateway NC800. This is a logical
network diagram and therefore does not necessarily correspond to the network cabling. The Ethernet LAN and
the WLAN are shown as a single logical network. No hubs or switches are shown. Logically, only the Motorola
Cellular Gateway NC800 and the computer in the DMZ are exposed to the Internet (are on the Internet side of
the firewall). Physically, the firewall is implemented on the Motorola Cellular Gateway NC800.

Figure 3. Motorola Cellular Gateway NC800 security measures shown in a logical network diagram
Firewall
The Motorola Cellular Gateway NC800 firewall protects the Motorola Cellular Gateway NC800 LAN from
undesired attacks and other intrusions from the Internet. It provides an advanced integrated stateful-inspection
firewall. The firewall:
• Maintains state data for every TCP/IP session on the OSI network and transport layers
• Monitors all incoming and outgoing packets and applies the firewall policy to each one
• Provides comprehensive logging for all rejected internal and external connection requests
• You can configure the firewall filters to set rules for port usage and to block specific IP domains and
networks.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 11 of 110
DMZ
A de-militarized zone (DMZ) has one or more computers logically located outside the firewall between a
Motorola Cellular Gateway NC800 LAN and the Internet. A DMZ prevents direct access by outside users to
private data. You can use a DMZ to set up a web server without exposing confidential data on your network. A
DMZ is also useful for people playing games that have a problem running a computer game’s protocol through a
firewall. DMZ provides the person playing games a way to expose a single host directly to the Internet and thus
overcome any problems where the firewall rules might cause packets to this computer to be blocked.
Wireless Security
To prevent unauthorized eavesdropping of data transmitted over the wireless LAN, you must enable wireless
security.
802.11b/g supports two subtypes of network authentication services: Open System and Shared key. Under
open system authentication, any wireless station can connect to the Motorola Cellular Gateway NC800 provided
that it knows the Service Set Identifier (SSID) of the Motorola Cellular Gateway NC800. If the Motorola Cellular
Gateway NC800 is broadcasting this information, then any wireless client can access the Motorola Cellular
Gateway NC800. Under Shared Key authentication the Motorola Cellular Gateway NC800 generates a random
128-bit challenge. The station returns the challenge, encrypted with a shared key—a "secret" key configured
into both the station and the Motorola Cellular Gateway NC800. The Motorola Cellular Gateway NC800 decrypts
the challenge, using a CRC to verify its integrity. If the decrypted frame matches the original challenge, the
station is considered authentic. The challenge/response handshake is repeated in the opposite direction for
mutual authentication.
By default the Motorola Cellular Gateway NC800 is set to open system authentication, which provides no
security for transmitted data. You can use either the Setup Wizard or the instructions in this guide to enable a
reasonable level of security by configuring a WEP key on the Motorola Cellular Gateway NC800. The same key
must also be configured on the wireless LAN clients (stations).
For even better security, the relatively new WLAN Protected Access Pre-Shared Key (WPA-PSK) option is also
supported by the Motorola Cellular Gateway NC800. However, in order to use WPA-PSK, you must ensure that
it is also supported on the wireless LAN clients.
A RADIUS server may also be used to do centralized authentication for WPA if PSK is not used.
You can also define a MAC access control list to restrict wireless LAN access to specified clients based on the
Client MAC address.
Virtual Private Networks
The Motorola Cellular Gateway NC800 allows multiple tunnel VPN pass-through operation to securely connect
remote computers over the Internet through the Motorola Cellular Gateway NC800. The Motorola Cellular
Gateway NC800:
• Identifies and forwards Point to Point Tunneling Protocol (PPTP) packets
• Identifies and forwards certain IPSec packets.
PPTP enables the implementation of secure, multi-protocol VPNs through private “tunnels” over the public
Internet. Through PPTP, it is possible for remote users to access their corporate networks and applications
from anywhere on the Internet. The Motorola Cellular Gateway NC800 identifies and forwards PPTP packets.
IPSec is a suite of protocols used to implement secure exchange of packets at the IP layer. VPNs using
Encapsulating Security Payload (ESP) in tunnel mode are supported. VPNs using Authentication Header (AH)
are not supported.

Installation Considerations
The Motorola Cellular Gateway NC800 is designed to let you access your network using a wireless connection
from virtually anywhere. Please keep in mind that the number, thickness and location of walls, ceilings or other
objects that the wireless signals must pass through may limit the range.
To maximize the Motorola Cellular Gateway NC800’s wireless range:
1. Keep the number of walls and ceilings between the Motorola Cellular Gateway NC800 and your
receiving device to a minimum – each wall or ceiling can reduce your Motorola Cellular Gateway
NC800’s range from 1-30 meters.
2. Building materials make a difference – metal or aluminum objects may have a negative effect on range.
Try to position the Motorola Cellular Gateway NC800 and computers with wireless adapters (clients) so
that the signal passes through thin walls or open doorways and not other materials.
3. Use the signal strength indicator present in most wireless adapters’ software to experiment with the
signal strength in various positions in the building where you are going to use the Motorola Cellular
Gateway NC800.
4. Keep the Motorola Cellular Gateway NC800 away (at least 1-2 meters) from electrical devices that
generate Radio Frequency (RF) noise.
For the average home or office, signal range should not be an issue. If you experience low or no signal strength
in areas of your home or office that you wish to access, consider positioning the wireless Motorola Cellular
Gateway NC800 in a location directly between the computers with wireless adapters. Additional wireless
gateways can be connected to provide better coverage in rooms or offices where the signal does not appear as
strong as desired.
LAN capacity:
The theoretical upper limit of the number of devices connected to a class C Ethernet and/or wireless LAN is
253. This upper limit is due to the IP address structure of a class C network. (Please refer to the Glossary for
more details on the IP address structure.) However, several factors should be kept in mind when designing
your network:
1. The devices on the network share the available bandwidth on the WAN link if simultaneous WAN
access is required.
2. As many as 32 wireless devices can be attached to the WLAN. However, it must be kept in mind that
each wireless client of the Motorola Cellular Gateway NC800 shares the available bandwidth on the
WLAN with all the other wireless clients on the WLAN.
3. The bandwidth on the Ethernet LAN would be shared if a device such as a hub is connected to the
Motorola Cellular Gateway NC800 to create a wired LAN with multiple devices.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 18 of 110
Connecting the Motorola Cellular Gateway NC800 to your network
The Motorola Cellular Gateway NC800 has three network interfaces, namely the WAN, LAN and WLAN
interfaces. This section describes how to connect your network devices to the Motorola Cellular Gateway
NC800 using these interfaces.
Connecting the Motorola Cellular Gateway NC800 to the CDMA Network
The following procedure is for assembling and powering up the Motorola Cellular Gateway NC800:
1. Be sure the Motorola Cellular Gateway NC800 is unplugged (not powered on).
2. Place the Motorola Cellular Gateway NC800 in a position that is close enough to the surface where the
external antenna for CDMA access will be mounted. The distance between the antenna and the
Motorola Cellular Gateway NC800 is determined by the length of the cable attached to the antenna.
3. Screw in the loose end of the cable into the antenna connector on the rear panel of the Motorola
Cellular Gateway NC800.
4. Mount the external antennas as described in the next section.
5. Plug the power cord into the power connector on the rear panel of the Motorola Cellular Gateway
NC800.
6. Plug the power adapter into the electrical outlet. This turns on the Motorola Cellular Gateway NC800.
7. Verify that the lights on the front panel cycle through the following sequence:
• The Power light turns on when AC power is connected to the Motorola Cellular Gateway
NC800 and indicates that the power supply is working properly.
• The Signal light indicates the presence of a CDMA signal. Good signal strength will make the
light appear solid green.
• The Link light turns on indicating a connection on the WAN interface.
• The Act light flashes when there is activity on the WAN link.
Mounting the external antenna
The external antenna can be mounted on a wall using suitable screws and anchors or directly on the glass of a
window using the supplied suction caps.
Window mounting the antenna directly on glass
• Clip the supplied rubber suction caps into the mounting holes of the antenna mounting bracket.
• Affix the antenna mounting bracket to the glass by gently pressing the suction cups against the glass
pane of the window until the suction cups grip the glass.
• Align the antenna alongside the mounting bracket and gently slide it down until it locks in position on the
mounting bracket.
Mounting the antenna on a wall
• Locate a suitable mounting position on a wall made of wood, concrete, masonry, or a wooden stud.
• Using the antenna mounting bracket as a template, drill 2 suitable holes for a pair of anchors and
screws to fasten the antenna mounting bracket securely onto the wall.
• Align the antenna alongside the mounting bracket and gently slide it down until it locks in position on the
mounting bracket.
Warning: The CDMA antenna must be located more than 20 cm (8 inches) from the WLAN antennas.
Warning: Before drilling holes, check the structure for potential damage to water, gas, or electric lines.

Wired Connections to the Motorola Cellular Gateway NC800 – Direct connection
The Motorola Cellular Gateway NC800 has two RJ-45 LAN connectors
available for direct connection to a computer on your network. You can use
either a straight through or a crossover cable between the computer and the
Motorola Cellular Gateway NC800 – the Motorola Cellular Gateway NC800
will automatically detect the cable configuration. Use category 5 cabling for
all Ethernet connections.
Each computer on the Ethernet LAN requires an Ethernet network interface
card (NIC) and driver software installed.
The physical wiring arrangement has no connection to the logical network
allocation of IP addresses.
Wired Connections to the Motorola Cellular Gateway NC800 – Connections via other network devices
If you need to connect to another network via another gateway or
need to expand the number of Ethernet ports by using a hub or a
switch you can connect one of these devices directly to the Motorola
Cellular Gateway NC800 using the LAN port. The port is designed to
automatically detect and handle both straight through and crossover
cables.
Wireless Connections to the Motorola Cellular Gateway NC800
Wireless communication occurs over radio waves rather than a
wire. Like a cordless telephone, a wireless LAN uses radio
signals instead of wires to exchange data. A wireless network
eliminates the need for expensive and intrusive wiring to connect
computers throughout the home or office. Mobile users can
remain connected to the network even when carrying their
laptops to different locations in the home or office.
Each computer on a wireless LAN requires an adapter for access
to the WLAN:
• For wireless laptop connections, a Motorola PCC11b
Wireless Card can be used in the PCMCIA slot.
• For wireless desktop connections, a Motorola USB11b
Wireless Adapter can be used to connect your PC USB
port.
You can connect any combination of 802.11g or 802.11b wireless clients to the Motorola Cellular Gateway
NC800.

This is the very first page that you see when the Motorola Cellular Gateway NC800’s configuration utility opens.
The settings on this page determine whether certain options on subsequent pages will be available. These
dependencies are highlighted on the relevant pages.
The default values displayed on this page will generally be sufficient. The purpose of each field is
described below in order to assist you to fill in appropriate values if you have more advanced
requirements.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 38 of 110
• Gateway Mode – If the device operates in router mode, the WAN interface is enabled and the DHCP
Server and Spanning Tree protocols can be enabled. If the device acts as an access point, it offers only
wireless and wired LAN connectivity to clients (stations). The WAN interface, the LAN DHCP Server
and the Spanning Tree Protocol are automatically disabled.
• Wireless LAN Interface – In order to utilize the Motorola Cellular Gateway NC800 wireless functions,
select Enabled. If you do not wish to utilize any wireless functions, make sure Disabled is selected.
(Note: No other wireless functions will be available unless you enable this setting.) .
• WAN Interface – The WAN interface can be enabled or disabled. If the WAN interface is disabled,
there is no access to the Internet via the cellular network. (Note: No other WAN functions on
subsequent pages will be available unless you enable this setting.)
• Firewall – If you do not want the Motorola Cellular Gateway NC800 to filter any packets you can disable
the Firewall feature entirely. The Motorola Cellular Gateway NC800 will then allow all packets to travel
through it. If the Firewall is enabled you will not be able to ping the Motorola Cellular Gateway NC800’s
WAN interface from the Internet – see the note below. You will, however still be able to ping Internet
addresses from the LAN or WLAN.
It’s a good idea to keep the firewall enabled if you are connecting to the Internet. The firewall
makes it difficult for outsiders to detect your network. It prevents outsiders from “ping-ing” your
network by blocking all ping requests originating from outside your network. Only those IP addresses
and ports that you specify are opened to traffic originating from the Internet.

Gateway-> LAN Interface
This page is used to configure the LAN settings of the Motorola Cellular Gateway NC800.
The default values displayed on this page will generally be sufficient. The purpose of each field is
described below to assist you to fill in appropriate values if you have more advanced requirements.
• Primary LAN IP Address – You have to assign a unique static IP address to the Motorola Cellular
Gateway NC800’s LAN 1 local interface. Being static, this IP address will not dynamically change and
will be the default Motorola Cellular Gateway NC800 address for all computers connecting to this
Motorola Cellular Gateway NC800 on the LAN 1 interface or WLAN interface. The default IP address for
this Motorola Cellular Gateway NC800 is 192.168.1.1. The dotted-decimal notation must be used. The
interested reader is referred to the glossary for more detailed information on IP addressing and subnet
masks. The LAN 1 interface is the wired Ethernet port on the back panel labeled LAN 1 and is bridged
together with the WLAN interface.
• Primary LAN Subnet Mask – IP network mask of the Motorola Cellular Gateway NC800 on the LAN 1
interface, e.g. 255.255.255.0. If you are intentionally using a different subnet mask on your local
network, enter the appropriate subnet mask. The dotted-decimal notation must be used. The interested
reader is referred to the glossary for more detailed information on IP addressing and subnet masks.
• DHCP Server
o Enable – The Motorola Cellular Gateway NC800 acts as a DHCP server by assigning IP addresses
to computers on the local area network.
Important: The DHCP server setting should not be enabled if any other DHCP servers
have been setup on the LAN network.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 40 of 110
o Disable – The Motorola Cellular Gateway NC800 does not assign IP addresses to computers on
the LAN. Select this setting if another DHCP server already exists on the network or if static IP
addresses are assigned. Please note that the Motorola Cellular Gateway NC800 itself must have a
statically assigned IP address because it is acting as a gateway to the LAN network, so its IP
address must be known and not change.
• LAN DHCP (only available if LAN DHCP Server is set to Enabled)
o DHCP Starting IP Address – Specifies the start of the address range that the DHCP server will
use, e.g. 192.168.1.100. The DHCP server will only assign IP addresses within the Start - End
range. IP addresses outside the range are assumed to be static IP addresses and can be used by
computers on the network that have a reserved IP address. The maximum number of IP addresses
that can be issued is 253. These addresses should fall within the address ranges reserved for
private Internets, unless the address range specified here has been assigned to you by IANA.
Please refer to the IP address structure entry in the glossary for more detail regarding the allowable
ranges.
o DHCP Ending IP Address – Specifies the end of the address range that the DHCP server will use,
e.g. 192.168.1.150.
o Lease Time – Specifies the number of seconds DHCP leases should be valid for. The maximum
lease time can be set to 86400 seconds. A short duration (e.g. 1 hour) is recommended if there are
more users than addresses. If users need to keep their addresses while the DHCP Server is
unavailable, then the duration should be set to longer than a possible DHCP Server outage. If it is
desirable to retain IP addresses even when devices are powered down, then the duration should be
set longer than any likely period of inactivity. See also the discussion in the section describing the
Gateway-> DHCP Leases screen.
• Secondary LAN IP Address – You have to assign a unique static IP address to the Motorola Cellular
Gateway NC800’s LAN 2 local interface. Being static, this IP address will not change and will be the
default Motorola Cellular Gateway NC800 address for all computers connecting to this Motorola Cellular
Gateway NC800 on the LAN 2 interface. The default IP address for this Motorola Cellular Gateway
NC800 is 192.168.2.1. The dotted-decimal notation must be used. The interested reader is referred to
the glossary for more detailed information on IP addressing and subnet masks. The LAN 2 interface is
the wired Ethernet port on the back panel labeled LAN 2.
• Secondary LAN Subnet Mask – IP network mask of the Motorola Cellular Gateway NC800 on the LAN
2 interface, e.g. 255.255.255.0. If you are intentionally using a different subnet mask on your local
network, enter the appropriate subnet mask. The dotted-decimal notation must be used. The interested
reader is referred to the glossary for more detailed information on IP addressing and subnet masks.
Gateway-> DHCP Leases
The Motorola Cellular Gateway NC800 is acting as a DHCP server if it automatically assigns IP addresses to
the computers connecting to it. The Motorola Cellular Gateway NC800 builds up a table of MAC addresses and
the IP address assigned to it. In a sense, a MAC address is “leasing” an IP address for a period of time. The
computer requesting an IP address from the Motorola Cellular Gateway NC800 will periodically “renew” the IP
address. The Motorola Cellular Gateway NC800 will then re-assign an IP address to it – in most cases this will
be the same address that was assigned to the computer previously.
If the computer does not renew its IP lease then the DHCP lease will expire. The Motorola Cellular Gateway
NC800 is then free to re-assign the IP address to the next computer requesting an IP address.
The DHCP leases page displays the current DHCP leases table. This page is for information only. No
values can be set on this page. In order to change DHCP related fields you need to go to the Gateway
-> LAN Interface page.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 41 of 110
• Host Name – The name of the computer that requested the IP address.
• MAC Address – The MAC address of the computer that requested an IP address.
• IP Address – The IP address that was assigned to the requesting MAC address.
• Expires In – The remaining period that the IP address is reserved for the specific MAC address.

Gateway-> Universal Plug and Play
The Motorola Cellular Gateway NC800 supports the UPnP Internet Gateway Device (IGD) 1.0 specification.
UPnP defines a set of common services (protocols) that devices can use to join a network and describe
themselves and their capabilities, enabling other devices to use them without a complicated set-up or
configuration.
The default values displayed on this page will generally be sufficient. The purpose of each field is
described below in order to assist you to fill in appropriate values if you have more advanced
requirements.
• UPnP (Enabled / Disabled) – Enable or disable Universal Plug and Play on the Motorola Cellular
Gateway NC800. Disabling UPnP does not cause additional configuration to be required on the
Motorola Cellular Gateway NC800. Enabling UPnP merely has the advantage that a UPnP enabled
machine will be able to detect the Motorola Cellular Gateway NC800 on the LAN.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 43 of 110
Gateway-> LAN STP
The Motorola Cellular Gateway NC800 supports LAN Spanning Tree 802.1d specification.
The default values displayed on this page will generally be sufficient. The purpose of each field is
described below in order to assist you to fill in appropriate values if you have more advanced
requirements.
• Spanning Tree Protocol (Enabled / Disabled) – Spanning Tree Protocol, supported on most bridges
and switches, is the tried and tested method for providing path redundancy while eliminating loops in
bridged networks. Loops create never-ending data paths, resulting in excessive system overhead.
Select Enabled if you want to enable this protocol.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 44 of 110
Gateway-> Login Settings
This page is used to configure the Login settings of the Motorola Cellular Gateway NC800.
The HTTP server allows you to configure the Motorola Cellular Gateway NC800 via a web browser. Access to
the Motorola Cellular Gateway NC800 configuration is controlled via the following parameters:
• Login Username – Enter the username required to access configuration web pages. The maximum
length of the username that you can enter is 63 characters.
• Login Password – Enter the password required to access the configuration pages. The password can
be up to 63 characters in length
• Gateway WAN Port – The port number required to access the configuration pages remotely via the
WAN interface. This can be a number between 0 and 65535. Leave this field empty if you do not want
the Motorola Cellular Gateway NC800 to be configurable via the WAN interface. The default is <blank>.
If you specify a port number (for example 8080) in the Gateway WAN
Port field you can access the Motorola Cellular Gateway NC800
configuration pages from the Internet by specifying the port number
when typing the Motorola Cellular Gateway NC800’s address. For
example, if your Motorola Cellular Gateway NC800’s WAN IP
address is 192.168.10.50 then the URL that you should use to open
the configuration pages is http://192.168.10.50:8080.
.

It is recommended to change the default username and default password for security reasons
Warning: If you specify a Motorola Cellular Gateway NC800 WAN HTTP Port anyone who knows
the Motorola Cellular Gateway NC800’s Internet IP address and password will be able to alter the
Motorola Cellular Gateway NC800’s settings.
Network
There are four pages in the Routing category:
Network-> Dynamic Routing This page contains enables and disables the RIP protocol.
Network-> Static Routing This page contains parameters that can be set to have static routing
between networks.
Network-> System Time This page allows the system time and date to be set as well as the
country settings.
Network-> VLAN This page sets the VLAN parameters which logically groups stations on
different LAN ports together.
The two screens in the routing category are mutually exclusive. If the Motorola Cellular Gateway NC800
Ethernet LAN interface is connected to a device that supports RIP, dynamic routing can be enabled on the
Network-> Dynamic Routing page. Otherwise static routes should be defined for devices on a LAN segment
that are different to the one served by the Motorola Cellular Gateway NC800 (if there is such a remote LAN
segment). This is done on the Network-> Static Routing page.
The diagram below shows an example topology where a static route would need to be defined if RIP was not
supported on the router.

In the diagram the three PCs connected to the router are located in the LAN segment with the address range
192.168.10.0 thru 192.168.10.255. The LAN segment between the Motorola Cellular Gateway NC800 and the
switch has the address range 192.168.1.0 thru 192.168.1.255. In order to route packets from the WLAN laptop
to the PC with IP address 192.168.10.10, a route to 192.168.10.0 must be defined in the Motorola Cellular
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 46 of 110
Gateway NC800. The router is a device on the Ethernet LAN of the Motorola Cellular Gateway NC800 and in
this example its address is 192.168.1.100. The following routing entry is therefore specified (refer to the next
section for a description of each field):
IP address Subnet Mask Gateway Metric Interface
192.168.10.0 255.255.255.0 192.168.1.100 1 LAN 1
If a user on the Internet wants to access the PC at 192.168.10.10, that user needs to specify the WAN IP
address of the Motorola Cellular Gateway NC800 in order to reach the PC. When the packet arrives at the
Motorola Cellular Gateway NC800, it routes it to the router which in turn routes it to the PC. The Motorola
Cellular Gateway NC800 uses its port forwarding tables to determine where to route the packet. Port forwarding
is described in the Firewall section of this document. If access from the Internet is a requirement, then the WAN
IP address of the Motorola Cellular Gateway NC800 would have to be made known to the user requiring such
access. A static IP address would therefore be preferable in such a situation.
Network-> Dynamic Routing
This page provides detailed settings for Dynamic Routing.
Dynamic Routing allows the Motorola Cellular Gateway NC800 to automatically adjust to physical changes in
the network's layout. The Motorola Cellular Gateway NC800, using the RIP v1 and v2 protocol, determines the
network packets' route based on the fewest number of hops between the source and the destination. The RIP
protocol regularly broadcasts routing information to other routers on the network.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 47 of 110
• Dynamic IP Routing – Enabled / Disabled dynamic routing of data between networks connected to the
Motorola Cellular Gateway NC800. If Disabled, no routing updates (RIP) are sent to or received from
other networks.
Network-> Static Routing
This page provides detailed settings for Static Routing.
If the Motorola Cellular Gateway NC800 is connected to more than one network, it may be necessary to set up a
static route between them. A static route is a pre-determined pathway that the IP packet must travel to reach a
specific host or network.
The Motorola Cellular Gateway NC800 supports up to 10 static routes. For every route that you want to define
you must supply the following information:
• Destination IP address – The destination IP address of the remote network or host to which to assign
a static route. If you are building a route to an entire network, be sure that the host portion of the IP
address is set to zero. For example, if the router on the remote network has an IP address of
212.100.1.1 and if you wanted to route to the entire network, rather than just to the router, you would
you would enter the IP address 212.100.1.0 as the destination IP address.
• Subnet Mask – The subnet mask indicates which portion of the destination IP Address is the network
portion and which is the host portion. If, for instance, you use a Subnet Mask of 255.255.255.0 (Class C
network) with the example shown above for destination IP, then this would indicate that the first three
numbers of a network IP address identifies this particular network, while the last number in the network
address (from 1 to 254) would identify the specific host.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 48 of 110
• Gateway IP address – IP address of the Motorola Cellular Gateway NC800 on the local network
segment to which packets destined for the remote network should be forwarded.
• Route Metric: The number of nodes that a data packet passes through before reaching its destination.
A node is any device on a network, such as switches, PCs, etc. Enter a decimal number between 0 and
15. The default value is 1.
• Route Interface – Select the appropriate interface to use when forwarding packets destined for the
remote network. Valid values are:
o LAN 1 - Destination is on the Primary LAN network.
o LAN 2 - Destination is on the Secondary LAN network.
o WAN - Destination is on another IP network. In most cases it will not be necessary to enter a routing
entry for WAN access.
It is usually not necessary to create a routing entry manually for WAN access to the Internet. WAN routing
information is obtained automatically by the Motorola Cellular Gateway NC800 when it communicates with the
ISP.
Network-> System Time
This page provides detailed settings for Time and Date settings.
This function synchronizes the Motorola Cellular Gateway NC800's date and time with a Network Time Protocol
(NTP) server or date and time supplied by the CDMA module. This functionality is necessary to time stamp
logging information.
• Set Date and Time – Manually set date and time or click the calendar icon to choose date and time.
When pressing the calendar icon, a pop-up appears as shown
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 49 of 110
• Network Time Protocol Server – The IP address of the NTP server (3 can be specified) that the NTP
client connects to. Decimal number specified in dotted notation.
• Time Zone – Select the time-zone closest to you. The Motorola Cellular Gateway NC800 uses this
information to format the current time as returned by the Network Time Protocol Server. If there is
daylight saving in the time zone specified, it will automatically be enabled. If daylight saving is not
applicable to the selected Time Zone no time adjustment will be made throughout the year.
Network-> VLAN
This page provides detailed settings for VLAN settings.
The VLAN concept logically groups stations on different LAN ports together (i.e. stations can see each other
even though they are on physically different LANs). All stations with the same VLAN identifier can "see" each
other.
Warning: The packets sent between the two PC’s are sent as VLAN tagged packets, therefore the
stations communicating over the VLAN must be able to handle VLAN tagged packets.
• VLAN ID – ID of the VLAN to enable or disable on the gateway. If enabled, the gateway will retransmit
all received tagged packets (with corresponding VLAN IDs) on both LAN1 and LAN2. If disabled, the
tagged packet will be dropped by the gateway.

WAN
There are two pages that affect the setup of the WAN interface of the Motorola Cellular Gateway NC800:
WAN-> IP Settings If the ISP specifies a static IP address for the Motorola Cellular Gateway
NC800, then that address and other related information provided by the ISP
must be filled in on this page.
WAN-> PPP Settings The ISP account information is filled in on this page.
WAN-> IP Settings
Use this page to configure the WAN interface if your ISP has assigned a static IP address to you. They will
provide most if not all information. For those fields that they do not provide information, leave the default values
in place.
Warning: The settings on this page become effective only if the WAN Interface is set to Enable on
the Gateway-> Basic Settings page.
The default values displayed on this page will be sufficient if the ISP assigns the IP address
automatically to the Motorola Cellular Gateway NC800. (A default value of 0.0.0.0 means that no IP
address is configured.) The purpose of each field is described below in order to assist you to fill in
appropriate values if the ISP specifies a static IP address for the Motorola Cellular Gateway NC800.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 51 of 110
• WAN IP Address – This is the Motorola Cellular Gateway NC800's IP Address as seen by external
users on the Internet (including your ISP). The default is 0.0.0.0 (i.e. dynamically assigned).
• WAN Subnet Mask – This is the Motorola Cellular Gateway NC800's subnet mask on the WAN
interface. The default is 0.0.0.0 (i.e. dynamically assigned).
• Default Gateway – You should enter your ISP server’s IP address here. The Motorola Cellular
Gateway NC800 will route all packets bound for the Internet to this address. Your ISP will then route the
packets onto the Internet. Please check with your ISP for the address to use here. The default is 0.0.0.0
(ie dynamically assigned).
• DNS Servers – You only need to enter one DNS server address here. If your ISP has supplied you with
more than one DNS server address you can enter them in here. The first DNS server is the preferred
DNS server meaning that DNS lookups will first be sent to this address before the alternate DNS
servers are used as backups. The default is a blank field. Up to three DNS servers can be entered.
You can test your ability to access the Internet by connecting to a well-known Internet web site such as

range of 0 to 2347.
• Fragmentation Threshold – This value indicates how much of the Motorola Cellular Gateway NC800’s
resources are devoted to recovering packet errors. The value should remain at its default setting of
2346. If you have decreased this value and experience high packet error rates, you can increase it
again within the range of 256 to 2346, but it is likely to decrease overall network performance. Only
minor modifications of this value are recommended.
• DTIM Interval – This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A
DTIM field is a count-down field informing clients of the next window for listening to broadcast and
multicast messages from the Motorola Cellular Gateway NC800. When the Motorola Cellular Gateway
NC800 has buffered broadcast or multicast messages for associated clients, it sends the next DTIM
with a DTIM Interval value. Clients of the Motorola Cellular Gateway NC800 hear the beacons and
awaken to receive the broadcast and multicast messages. This value should remain at its default value
of 3 but the valid range is 1 to 255.
• Beacon Interval – Specify a Beacon Interval between 1 and 65535 milliseconds. The default of 100
milliseconds is the recommended value. Beacons are packets broadcast by the Motorola Cellular

Wireless LAN-> MAC Restriction
This page provides more advanced settings for allowing and disallowing specific MAC addresses of wireless
LAN points.
This feature allows you to prevent users on the LAN network from using the Motorola Cellular Gateway NC800's
resources based on their MAC addresses.
A MAC address is a 12-digit code assigned to a unique piece of hardware for identification. The MAC address
component is fixed and is independent of the component's IP address. This means that you can block a specific
component irrespective of the component's IP address.
Warning: The settings on this page become effective only if the Wireless LAN Interface is set to
Enable on the Gateway-> Basic Settings page.
The default values displayed on this page will generally be sufficient. The purpose of each field is
described below in order to assist you to fill in appropriate values if you have more advanced
requirements.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 58 of 110
The Motorola Cellular Gateway NC800 supports up to 20 MAC filtering entries.
• MAC Filter Mode
o Disabled - Filtering is ignored. All packets are allowed through.
o Allow – Only the specified MAC addresses are allowed through. This is the most secure method,
but requires you to add each MAC address individually. It has the advantage that all unknown MAC
addresses are blocked.
o Deny – The specified MAC addresses are blocked. Use this method to block specific users.
• MAC Addresses – The MAC addresses to block/allow for users on the LAN. MAC Addresses must be
in the format XX:XX:XX:XX:XX:XX where XX are Hexadecimal digits.
Important: If the MAC address list is empty you must set the MAC Filter Mode to Disabled or
Deny. An empty MAC address table does not allow WLAN workstations to communicate with the
Motorola Cellular Gateway NC800 if the MAC Filter Mode field is set to Allow
Wireless LAN-> WEP Security
This page allows you to configure the Motorola Cellular Gateway NC800's WEP Security settings.
Warning: The settings on this page become effective only if the Wireless LAN Interface is set to
Enable on the Gateway-> Basic Settings page.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 59 of 110
802.11b/g supports two types of WEP security services: Open System and Shared key. Under open system
authentication, any wireless station can connect to the Motorola Cellular Gateway NC800 provided that it knows
the SSID of the Motorola Cellular Gateway NC800. If the Motorola Cellular Gateway NC800 is broadcasting this
information, then any wireless client can access the Motorola Cellular Gateway NC800. Under Shared Key the
Motorola Cellular Gateway NC800 generates a random 128-bit challenge. The station returns the challenge,
encrypted with a shared key—a "secret" key configured into both the station and the Motorola Cellular Gateway
NC800. The Motorola Cellular Gateway NC800 decrypts the challenge, using a CRC to verify its integrity. If the
decrypted frame matches the original challenge, the station is considered authentic. The challenge/response
handshake is repeated in the opposite direction for mutual authentication.
WEP data encryption is a weaker encryption method than that used by WPA-PSK. Either 64-bit or 128-bit keys
can be specified. If either WEP Data Encryption or Shared-Key Authentication is required, one or more WEP
encryption keys must be provided. Note that WEP data encryption can be provided even if shared-key
authentication is not required and vice versa.
• Authentication. - Selects the WEP authentication method.
o Open – all stations are granted access. The default value is Open.
o Shared Key – stations possessing the WEP key are allowed access.
o 802.1X – 802.1X is used to perform authentication using a RADIUS server and WEP key
distribution.
Warning: 802.1x Authentication method requires RADIUS server configuration.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 60 of 110
• Network Re-auth interval – The interval in seconds at which the Motorola Cellular Gateway NC800
distributes a new WEP key. This parameter is valid only if WEP Authentication = 802.1X. The default
value is 36000.
• WEP Encryption
o Enabled – data packets are WEP-encrypted.
o Disabled – WEP encryption is performed.
If WEP Authentication = 802.1X, then WEP Encryption = Enabled.
The default is Disabled.
• Network Key (1 – 4) – Enter up to four different network keys. Only one is in use as determined by the
"Current Network Key” setting. You can choose between 128-bit or 64-bit WEP encryption. Both allow
you to specify up to four keys, but only the selected “Current Network Key” is used. If you are using
64-bit WEP encryption, then the key must be exactly 10 hexadecimal or 5 ASCII characters in length. If
you are using 128-bit WEP encryption, then the key must be exactly 26 hexadecimal or 13 ASCII
characters in length. Valid hexadecimal digits are “0”-“9” and “A”-“F”. This is only valid if WEP
authentication is not Open, or WEP encryption is enabled. Default is blank for all keys.
Note: When Authentication is set to 802.1X, only Network Keys 2 or 3 can be used.
• Current Network Key – The secret key selected for encrypting outbound traffic and/or authenticating
clients. Decimal number between 1 and 4. This is only valid if WEP authentication is not Open, or WEP
encryption is enabled. Default is 1.
Note: When Authentication is set to 802.1X, only Network Keys 2 or 3 can be selected.
Warning: The security settings on the WLAN adapters on the workstations or laptops need to be
set up to match the security settings on the Motorola Cellular Gateway NC800. The wireless links
between the workstations/laptops and the Motorola Cellular Gateway NC800 need to be restarted
after the security settings have been changed.
Wireless LAN-> WPA Security
This page allows you to configure the Motorola Cellular Gateway NC800's WPA Security settings.
Warning: The settings on this page become effective only if the Wireless LAN Interface is set to
Enable on the Gateway-> Basic Settings page and Authentication is set to Open on the Wireless
LAN-> WEP security.
The Motorola Cellular Gateway NC800 supports WLAN Protected Access (WPA), WPA2 (an extension of WPA,
based on 802.11i) and WPA Pre-Shared Key (WPA-PSK) authentication methods. WPA, WPA2 and WPA-PSK
are all more secure than WEP. The encryption methods that can be used are Temporal Key Integrity Protocol
(TKIP) or Advanced Encryption Standard (AES) or both. AES is more secure, but is only supported by newer
WLAN devices.
If the authentication method is WPA-PSK, a pre-shared key is entered into the Cellular Gateway NC800, and an
external RADIUS server is not needed. If the authentication method is not WPA-PSK, an external RADIUS
server is required to perform authentication and key distribution.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 61 of 110
• WPA Authentication– Enables or Disables WPA/WPA2 authentication method.
• WPA Pre-authentication
o Enabled: Allows a WPA2 client to pre-authenticate with the Gateway toward which it is moving,
while maintaining a connection to the Gateway it's moving away from.
o Disabled: Pre-authentication is disabled.
• WPA Encryption
o TKIP - Temporal Key Integrity Protocol
o AES - Advanced Encryption Standard
o TKIP+AES - both enabled
• WPA-PSK Authentication
o Enabled – Authentication is by possession of a pre-shared key.
o Disabled – Authentication requires the use of a higher-layer authentication method supported by a
remote authentication server (RADIUS server).
• WPA Pre-Shared Key – Sets the WPA Pre-Shared Key (PSK). The key must be between 8 and 63
ASCII characters or 64 hexadecimal digits. Valid hexadecimal digits are “0”-“9” and “A”-“F”. This
parameter is valid if WPA PSK Authentication is Enabled.
• Network Re-auth Interval – The interval, in seconds, at which the gateway will request the WLAN
client to re-authenticate itself.
• Network Key Rotation Interval – The interval, in seconds, at which a new group key (GTK) is
distributed. A value of 0 means there is no periodic GTK distribution.
Warning: The security settings on the WLAN adapters on the workstations or laptops need to be
set up to match the security settings on the Motorola Cellular Gateway NC800. The wireless links
between the workstations/laptops and the Motorola Cellular Gateway NC800 need to be restarted
after the security settings have been changed. WPA-PSK can only be used on the Motorola
Cellular Gateway NC800 if the clients support it.

Firewall
The firewall on the Motorola Cellular Gateway NC800 is a security software system that enforces an access
control policy between the Internet and the Motorola Cellular Gateway NC800 LAN. A firewall determines which
information passes in and out of the network.
There are five pages in the Firewall category:
Firewall-> Permanent Port Forwarding If external users from the Internet need to have access to certain
services on the LAN connected to the Motorola Cellular Gateway
NC800, then the relevant ports and the addresses of the devices
providing those services are specified on this page.
Firewall-> Application Port Forwarding Some services provided to external users from the Internet need to
use different ports for inbound and outbound traffic. The relevant
ports and the addresses of the devices where these applications are
running are specified on this page.
Firewall-> MAC Address Filtering If certain devices on the LAN must be prevented from accessing the
Motorola Cellular Gateway NC800, then their MAC addresses can be
specified on this page.
Firewall-> Port Filtering If access to the Internet must be restricted, then the relevant
information is entered on this page.
Firewall-> DMZ Host If a DMZ host is provided, its IP address is specified on this page.
Firewall-> Permanent Port Forwarding
This function allows external users from the Internet to have WAN access to public services on the LAN
network. These public services are specialized Internet applications such as Web servers, FTP servers and e-
mail servers. These types of requests from the external users are forwarded by the Motorola Cellular Gateway
NC800 to the appropriate computer on the LAN network.
No port forwarding takes place unless at least one entry exists in the port forwarding table. Any incoming packet
that does not match the port numbers on the incoming WAN interface is dropped.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 65 of 110
You can specify up to 10 port forwarding entries:
• Protocol – Select TCP or UDP for the protocol to be forwarded.
• WAN Port Start – The start of the range of port numbers at the incoming WAN interface. To configure a
single port number, leave the starting or ending port number empty. Decimal numbers between 0 and
65535.
• WAN Port End – The end of the range of port numbers at the incoming WAN interface. To configure a
single port number, leave the starting or ending port number empty. Decimal numbers between 0 and
65535.
• LAN IP Address – The IP address of the server on the LAN to forward the packet to. Decimal number
specified in dotted notation.
• LAN Port Start – The start of the range of port numbers at the outgoing LAN interface. Decimal
numbers between 0 and 65535.
• LAN Port End – The end of the range of port numbers at the outgoing LAN interface. To configure a
single port number leave the starting or ending port number empty. Decimal numbers between 0 and
65535.
• Enabled – Tick this box to activate the entry.
Port forwarding is an advanced function. No changes should be made to the settings without a thorough
understanding of the relevant networking concepts.
Any PC exposed to the Internet using the Permanent Port Forwarding feature should have its DHCP
client functionality disabled and should have a new static IP address assigned to it. This is because its
IP address may change when using the DHCP function.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 66 of 110
Firewall-> Application Triggered Port Forwarding
Some programs, such as Internet games and videoconferencing, require multiple ports for data transmission.
Data transmitted using File Transfer Protocol (FTP), for example, is sent from your computer via one port and
related data (e.g. an acknowledgement of receipt of data) returns via another port. These multiple port
transmissions may cause problems with network address translation (NAT) because the NAT service
anticipates that packets related to data sent via one port will return to the same port.
If you are having trouble running a particular program on your network, you may need to establish application-
triggered port forwarding for that program. Essentially, application-triggered port forwarding tells the Motorola
Cellular Gateway NC800 how to direct traffic across networks.
To configure port forwarding for a specific program, you must specify the protocol that the application uses, the
outbound port from which data associated with that particular protocol should be sent, and the inbound port or
ports to which related data will return. When the Motorola Cellular Gateway NC800 receives a data packet from
the wide area network that uses the specified protocol, it sends the packet to the client on your network that is
currently using the program.
The inbound ports that you specify will open only when data is sent from the corresponding outbound port.
These ports will close again after a certain amount of time has elapsed with no data sent to the inbound port.
You can specify one port or a range of ports.
You can only establish application-triggered port forwarding for programs that use the Transmission Control
Protocol (TCP) or User Datagram Protocol (UDP).
To identify the protocol that a program uses and the ports to which the data should be sent, consult the
documentation for that program.
The Motorola Cellular Gateway NC800 additionally allows Inbound port(s) to be mapped to the actual
application inbound ports. These mapped ports are configured in the To Port fields.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 67 of 110
You can specify up to 10 Application Triggered port forwarding entries.
• Outbound Protocol – The outbound protocol (TCP or UDP) used by the application.
• Outbound Port Start – The start of the range of outbound port numbers used by the application. Valid
values are 0 – 65535.
• Outbound Port End – The end of the range of outbound port numbers used by the application. To
configure a single mapped port number leave the starting or ending mapped port number empty. Valid
values are 0 – 65535.
• Inbound Protocol – The inbound protocol (TCP or UDP) used by the application.
• Inbound Port Start – The start of the range of port numbers on which responses can be received. Valid
values are 0 – 65535.
• Inbound Port End – The end of the range of port numbers on which responses can be received. To
configure a single UDP port number, leave the starting or ending inbound port number empty.
• To Port Start – The start of the range of application port numbers to which the inbound ports are
mapped. This mapping is optional. Valid values are 0 – 65535.
• To Port End – The end of the range of application port numbers to which the inbound ports are
mapped. This mapping is optional. To configure a single mapped port number leave the starting or
ending mapped port number empty. Valid values are 0 – 65535.
• Enabled – Tick this box to activate the entry.
Port forwarding is an advanced function. No changes should be made to the settings without a
thorough understanding of the relevant networking concepts.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 68 of 110
Any PC exposed to the Internet using the Application Triggered Port Forwarding feature should have
its DHCP client functionality disabled and should have a new static IP address assigned to it. This is
because its IP address may change when using the DHCP function.
Firewall-> MAC Address Filtering
If you want to block specific users from accessing the Motorola Cellular Gateway NC800 via the LAN interface
then you can use the MAC Address Filtering feature.
A MAC address is a 12-digit code assigned to a unique piece of hardware for identification, like a social security
number. The MAC address component is fixed and is independent of the component's IP address. This means
that you can block a specific component irrespective of the component's IP address.
The Motorola Cellular Gateway NC800 supports up to 20 MAC filtering entries.
• MAC Filter Mode
o Disabled – No MAC filtering is done.
o Allow – Allow only the specified MAC addresses access to the LAN interface. This is the most
secure method, but requires you to add each MAC address individually. It has the advantage that all
unknown MAC addresses are blocked.
o Deny – Prevent the specified MAC addresses from accessing the LAN interface. Use this method to
block specific users.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 69 of 110
• LAN MAC Filters – You can specify a list of up to 20 MAC addresses that will be filtered according to
the MAC Filter Mode. MAC Addresses must be in the format xx:xx:xx:xx:xx:xx where xx are
Hexadecimal digits.
If the MAC address list is empty you must set the MAC Filter Mode to Disabled or Deny. An empty
MAC address table does not allow LAN workstations to communicate with the Motorola Cellular
Gateway NC800 if the MAC Filter Mode field is not set to Disabled or Deny.
Firewall-> Port Filtering
This function blocks specific internal users (on the LAN side) from accessing the Internet (on the WAN side).
TCP and/or UDP packets are filtered on any combination of the following:
• The source IP address
• The destination port number (UDP or TCP)
• Day of the Week
• Time of the Day
You can specify up to 10 TCP/UDP packet filters.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 70 of 110
• LAN IP Address Range – The IP address range of LAN users to block. To configure a single IP
address leave the first or second entry empty. To block TCP/UDP ports for all LAN users type * in the IP
address fields. Dotted-Decimal notation must be used.
• Protocol – The protocol type (TCP or UDP) for this LAN IP Address Range.
• Destination Port Range – The start and end port numbers of the range of ports to block for LAN users.
Decimal numbers between 0 and 65535 only.
• From Day – Select the day of the week to activate the filter.
• To Day – Select the day of the week to deactivate the filter (the filter is still active for this day, but not
from the next day onwards).
• From Hour – Select the hour of the day to activate the filter.
• To Hour – Select the hour of the day to deactivate the filter (the filter is still active for this hour, but not
from the next hour onwards).
• Enabled – Tick this box to activate the entry.
Firewall-> DMZ Host
This feature allows a single computer on your local network to be exposed to all users on the Internet allowing
unrestricted two-way communication. The host computer therefore exists in a demilitarised zone (DMZ) and
bypasses all the firewall security. You may want to expose a single computer to allow certain applications such
as internet-gaming and video conferencing using for example Microsoft’s NetMeeting.
DMZ hosting forwards all the ports (TCP and UDP) at the same time to one specified computer.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 71 of 110
• DMZ IP Address – The only setting required is the IP address of the computer to expose to the
Internet. The exposed computer will receive all data packets that are sent to the Motorola Cellular
Gateway NC800’s WAN IP address. Leave this blank if you do not want to specify a DMZ Host. Decimal
number specified in dotted notation.
Important: DMZ Hosting is an Advanced function. No changes should be made without a
thorough understanding of networking concepts.
Warning: Any Internet user who knows this address can connect to the exposed computer. There
are methods to scan for open ports on the exposed computer so using this feature is a security
risk.
Any PC exposed to the Internet using the DMZ Host feature should have its DHCP client functionality
disabled and should have a new static IP address assigned to it. This is because its IP address may
change when using the DHCP function.

Appendix B: Troubleshooting
This section discusses possible problems and outlines possible solutions.
1. I cannot access the Motorola Cellular Gateway NC800’s web-based Configuration utility.
It is recommended, but not required, that you configure the Motorola Cellular Gateway NC800 via a
computer that is directly connected to the Motorola Cellular Gateway NC800’s LAN interface.
• Check that the Motorola Cellular Gateway NC800 is properly installed and is powered ON.
• Check that there is a network connection between the Motorola Cellular Gateway NC800 and the
computer that is being used to configure the Motorola Cellular Gateway NC800.
o Check that the computer is connected to the Motorola Cellular Gateway NC800, either directly or
via another network path for example via a hub or a switch.
o Check that the computer’s Ethernet adapter is working correctly.
Ensure that the drivers for the network adapters are installed correctly.
Check the status of the network connection. It should say “connected” or indicate the speed
of the connection e.g. 10 Mbps or 100 Mbps.
o Check that the PC’s IP address is in the same range and subnet as that of the Motorola Cellular
Gateway NC800.
o Try to ping the Motorola Cellular Gateway NC800 to make sure that it is responding. Open a
command console window (Go to Start -> Run. Type in cmd (if you are using Windows 98 / ME
type in command). When the console window opens, type in ping 192.168.1.1. If you have
changed the IP address of the Motorola Cellular Gateway NC800 then use that address instead.
The Motorola Cellular Gateway NC800 should respond with four replies.
• Check the Security Level set on the Browser. Depending on the browser, a High Security Level might
prevent Javascripts from being executed on the PC. On the browser configuration, set the Internet
Security to Low and ensure that Javascripting is enabled.
A quick way to check a network
connection is to use the ping
command. Type in ping
xxx.xxx.xxx.xxx where xxx is the IP
Address that you want to test. The
command then sends test packets to
the destination address. If there exists a
network connection to the address, you
should see four replies.
Be sure to use the correct IP address.
2. How do I check that my LAN Ethernet adapter is working
correctly?
• Select Control Panel from My Computer. Go to Network
Connections and double-click on the Ethernet Adapter.
• If your network card is working correctly:
o The Status will be Connected.
o The Sent and Received byte counter will increase as
data is sent and received via the network adapter.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 88 of 110
3. I cannot establish a wireless connection to the Motorola Cellular Gateway NC800.
Please consult the user guide of your computer’s WLAN adaptor when configuring any of the
settings discussed below.
• Check that you are using the same SSID and channel number as the Motorola Cellular Gateway
NC800. If either one is not the same then the wireless data packets will be ignored by the Motorola
Cellular Gateway NC800.
• If the Motorola Cellular Gateway NC800 is set to use WEP encryption then ensure that the wireless
adapter on the client is also set accordingly. Make sure the encryption level (i.e. whether a 64-bit or
128-bit key is used) is set to the same level on both the client and the Motorola Cellular Gateway
NC800. Also check that the encryption keys are the same.
4. My wireless LAN connection is being dropped intermittently.
• Please refer to the Installation Considerations section for more information on how to optimally
position wireless network devices.
• Check the antenna orientation on the Motorola Cellular Gateway NC800.
• Check to see if other electronic equipment is not interfering with the wireless data transmissions.
• Use the laptop or workstation’s signal strength indicator to see what the signal strength is at the current
location. It could be that the signal strength is just too low for a reliable connection. In this case you
need to move the wireless adapter closer to the Motorola Cellular Gateway NC800 for increased signal
strength.
5. The network is configured correctly, but the Motorola Cellular Gateway NC800 is not responding
• Check to see if any of the lights (LEDs) on the Motorola Cellular Gateway NC800 are flickering at all.
• If the is no flickering for an extended period of time then you can try to reset the Motorola Cellular
Gateway NC800 by pressing the Reset button at the back of the Motorola Cellular Gateway NC800. Do
not hold the Reset button in, only press it once and release it again. This will reset the Motorola Cellular
Gateway NC800.
6. I do not know the IP address / User name / Password of the Motorola Cellular Gateway NC800
anymore.
In some cases, the IP address / User Name / Password of the Motorola Cellular Gateway NC800 may not be
known anymore, making it impossible to connect to the web-based Configuration Utility.
• After you have tried all other methods of trouble shooting, you can restore the Motorola Cellular
Gateway NC800’s factory default settings.
o Locate the Reset button on the back of the Motorola Cellular Gateway NC800.
o Press the Reset button and hold it down for 10 seconds.
o Release the Reset button.
o The Motorola Cellular Gateway NC800 will reboot and all the settings will be set according to the
factory default settings.
o You will have to redirect any open web browser to the Motorola Cellular Gateway NC800’s default
IP address: 192.168.1.1, using the default user name (admin) and password (admin).
7. When using DHCP on the LAN interface, the IP address that my computer receives is not correct.
• Ensure that there is no other DHCP server active on the same LAN segment that the Motorola Cellular
Gateway NC800 is located on. If more than one DHCP server is active on your network you could see
that some computers receive IP addresses from the first DHCP server and the rest of the computers
from the next. This will cause major network problems and should be avoided by only having ONE
DHCP server active on a network.
• Check that the Motorola Cellular Gateway NC800’s DHCP starting and ending DHCP IP address
ranges are correct.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 89 of 110
8. I cannot connect to the Internet via the Motorola Cellular Gateway NC800.
• If your Cellular Carrier or ISP is using PPP, then check that the WAN-> PPP Config settings are
configured correctly.
• Try to ping the WAN Interface port IP address.
• Try to ping your ISP’s default Motorola Cellular Gateway NC800 – check to see if the modem’s activity
lights are flickering when you do this.
• Try to ping a well-known Internet IP address such as www.motorola.com.
9. I need to access the Motorola Cellular Gateway NC800’s configuration remotely.
To access the Motorola Cellular Gateway NC800’s web-based configuration utility from the Internet you need to:
• Under Gateway-> Login Settings specify a Gateway WAN Port.
• A good value to use is 8080.
• To open the web-based utility, open a browser to http://<IP>:8080 where <IP> is the IP address of the
Motorola Cellular Gateway NC800’s WAN Interface.
• You get the WAN Interface IP address from the WAN->IP Settings pages.
• When prompted, type in the same username and password that you would normally use when opening
the web-based configuration utility.
10. I do not see the full 54 Mbps throughput when using the wireless interface.
As with any wireless protocol, 802.11g has overhead associated with it that limits performance. While signaling
data rates of up to 54 Mbps may be achieved, like most shared media (e.g. Ethernet) throughput will be
significantly less.
There are two scenarios for 802.11g performance. In an environment with only 802.11g clients, throughput of up
to 23 Mbps is expected. This performance is equal to that of 802.11a, although 802.11g is usually available over
a greater range - distance - from the Motorola Cellular Gateway NC800. The second scenario is when 802.11b
clients are present. RTS/CTS flow control (a signaling technique used by the 802.11 standard) must be used to
allow 802.11b clients to recognize and establish communications with 802.11g access points. This leads to
delays in transmission and drops peak throughput to about 10 Mbps. 802.11g performance is still well in excess
of the maximum measured speeds of 4-5 Mbps for 802.11b.
The use of RTS/CTS is important because it provides determinism to the wireless network, ensuring a minimum
bandwidth for each user. Like Ethernet, 802.11 LANs normally use a "carrier sense media access" mechanism
to signal transmission without asking for permission from the network. As the network becomes highly loaded,
collisions occur more frequently, and the network can become saturated with packet retransmission attempts
that eventually make it impossible for any data to get through. RTS/CTS provide a more formalized flow-control
mechanism that avoids this problem.
For optimal throughput keep the following in mind:
• Refer to the section on “Installation Considerations” for information on how to optimally
position the Motorola Cellular Gateway NC800.
• Do not connect more than 32 wireless clients to the Motorola Cellular Gateway NC800.
Rather spread the wireless clients over more than one Motorola Cellular Gateway NC800.
• Try to keep the number of 802.11b wireless clients to a minimum. The Motorola Cellular
Gateway NC800 is compatible with 802.11b clients, but this degrades the overall wireless
performance of the network. If at all possible, try to use only 802.11g wireless adapters in
your network.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 90 of 110
11. I need to set a static IP address on a PC.
The Motorola Cellular Gateway NC800 provides a DHCP server that automatically assigns IP numbers to PCs
on the network. Sometimes, you need to assign a specific IP address to a computer e.g. when you want to
configure a DMZ Host.

organization’s network. Each machine that can connect to the Internet needs a unique IP
address. When an organization sets up its computer users with a connection to the Internet,
an IP address must be assigned to each machine. Without DHCP, the IP address must be
entered manually at each computer and if computers move to another location in another
part of the network, a new IP address must be entered. DHCP lets a network administrator
supervise and distribute IP addresses from a central point and automatically sends a new
IP address when a computer is plugged into a different place in the network. DHCP uses
the concept of a “lease” or amount of time that a given IP address will be valid for a
computer. The lease time can vary depending on how long a user is likely to require the
Internet connection at a particular location. It’s especially useful in education and other
environments where users change frequently. Using very short leases, DHCP can
dynamically reconfigure networks in which there are more computers than there are
available IP addresses. DHCP supports static addresses for computers containing Web
servers that need a permanent IP address. DHCP enables the automatic reuse of unused
IP addresses. The Motorola Cellular Gateway NC800 contains a built-in DHCP server that
assigns private IP addresses to clients.
Directional
antenna
An antenna that concentrates transmission power into a direction, thereby increasing
coverage distance at the expense of coverage angle. Directional antenna types include
yagi, patch and parabolic dish.
Diversity
antennas
Two identical antennas located a small distance apart to reduce multipath distortion and
improve wireless reception. Properly placed diversity antennas improve Motorola Cellular
Gateway NC800 wireless reception.
DNS The Domain Name System is the Internet system for converting domain names to IP
addresses. A domain name is a meaningful and easy-to-remember “handle” for an Internet
address. A DNS server contains a table matching domain names such as
Internetname.com to IP addresses such as 192.169.9.1. When you access the world-wide
web, a DNS server translates the URL displayed on the browser to the destination website
IP address. The DNS lookup table is a distributed Internet database; no one DNS server
lists all domain name to IP address matches.
Domain name A unique name, such as motorola.com, that maps to an IP address. Domain names are
typically much easier to remember than are IP addresses.
Dotted-
decimal
notation
Method of representing an IP address or subnet mask using four decimal numbers called
octets. Each octet represents eight bits. In a class C IP address, the octets are
network.network.network.host. The first three octets together represent the network address
and the final octet is the host address. In the Motorola Cellular Gateway NC800 LAN default
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 96 of 110
configuration, 192.168.100 represents the network address. In the final octet, the host
address can be from 2 to 254. See IP Addresses.
download To copy a file from one computer to another. You can use the Internet to download files
from a server to a computer.
downstream In a CDMA network, the direction of data received by the computer from the Internet.
driver A software program that allows a computer to use and communicate with equipment or
peripherals installed on the computer. For example, network interface cards (NICs) require
drivers to allow the computer to communicate with the network through the NIC.
DSSS Direct Sequence Spread Spectrum is an IEEE 802.11b RF modulation protocol. It combines
a data signal at the sending station with a higher data rate bit sequence, which many refer
to as a chip sequence (also known as processing gain). A high processing gain increases
the signal's resistance to interference. The minimum processing gain that the FCC allows is
10, and most products operate under 20.
DTIM Delivery Traffic Indication Message.

endpoint A VPN endpoint terminates the VPN at the gateway so that computers on the Motorola
Cellular Gateway NC800 LAN do not need VPN client software to tunnel through the
Internet to the VPN server.
ESP Encapsulating Security Payload.
Ethernet The most widely used LAN type, also known as IEEE 802.3. The most common Ethernet
networks are 10Base-T, which provide transmission speeds up to 10 Mbps, usually over
unshielded, twisted-pair wire terminated with RJ-45 connectors. Fast Ethernet (100Base-T)
provides speeds up to 100 Mbps. Base means baseband technology and T means twisted
pair cable. Each Ethernet port has a physical address called the MAC address.
Token Ring is another method to access a LAN, but not widely used. Ethernet can be used
on a shared network, where all clients share the bandwidth or on a switched network where
each sender and receiver pair has the full bandwidth. Ethernet uses a technology that
broadcasts each frame onto a medium such as wire or fiber. All computers, on the network,
are listening. The computer with the matching destination address accepts the frame and
checks for errors. Ethernet was invented in 1973 by Robert Metcalfe and David Boggs of
Xerox. It ran at 2.93 megabits per second (Mbps). Today Ethernet devices are available
that communicate at 1 gigabits per second (Gbps).
F
Fast Ethernet An Ethernet Network that will support up to 100 megabits per second of data transfer.

gateway A device that enables communication between networks using different protocols. The
Motorola Cellular Gateway NC800 enables multiple computers supporting IEEE 802.11b/g
and/or Ethernet to share a single Internet connection. A gateway is often included as part of
a network switch. A gateway can also be implemented as software on a computer.

header The data at the beginning of a packet that identifies what is in the packet.
hexadecimal A base-sixteen numbering system that uses sixteen sequential numbers (0 to 9 and the
letters A to F) as base units before adding a new position. On computers, hexadecimal is a
convenient way to express binary numbers.
hub A hub offers a single collision domain among multiple wired users. When one user's
Ethernet NIC sends data, all other stations connected to the LAN will hold off sending data
until the medium is idle. A traditional wireless access point (AP) most closely resembles a
hub. A hub performs no data filtering. See also bridge and gateway.
hop The interval between two gateways on an IP network. The number of hops a packet
traverses toward its destination (called the hop count) is saved in the packet header. For
example, a hop count of six means the packet has traversed six gateways. The packet hop
count increases as the time-to-live (TTL) value decreases.
host In IP, a host is any computer supporting end-user applications or services with full two-way
network access. Each host has a unique host number that combined with the network
number forms its IP address. Host also can mean:

I
IANA The Internet Numbering Address Authority (IANA) is an organization under the Internet
Architecture Board (IAB) of the Internet Society that oversees IP address allocation. It is
under a contract from the U.S. government.
IEEE The Institute of Electrical and Electronics Engineers. The IEEE describes itself as “the
world’s largest technical professional society, promoting the development and application of
electro technology and allied sciences for the benefit of humanity, the advancement of the
profession, and the well-being of our members.” The IEEE fosters the development of
standards that often become national and international standards. The organization
publishes a number of journals, has many local chapters, and several large societies in
special areas, such as the IEEE Computer Society. The IEEE (http://www.ieee.org) is
accredited by ANSI.
IEEE 802.3 See Ethernet.
IEEE 802.11b One of the IEEE standards for wireless networking hardware. Products that adhere to a
specific IEEE standard will work with each other, even if they are manufactured by different
companies. The 802.11b standard specifies a maximum data transfer rate of 11Mbps, an
operating frequency of 2.4GHz, and WEP encryption for security.
It uses Direct Sequence Spread Spectrum modulation in the unlicensed 2.4 GHz frequency
band also used by cordless phones and microwave ovens, therefore range and throughput
are affected by 2.4 GHz phones and microwave ovens operating in the vicinity. 802.11b
networks are also referred to as WLAN networks.
IEEE 802.11g Refers to the extension of the IEEE 802.11 standard for wireless networking. The 802.11g
specification used by the Motorola Cellular Gateway NC800 specifies a maximum data
transfer rate of 54Mbps using OFDM modulation, an operating frequency of 2.4GHz,
backward compatibility with IEEE 802.11b devices and WEP encryption as well as WPA-
PSK for security.
The higher speed comes from using Orthogonal Frequency Division Multiplexing (OFDM)
modulation. It is backwards compatible with 802.11b because it also uses the 2.4 GHz
frequency and is therefore also affected by 2.4 GHz phones and microwave ovens
operating in the vicinity.
IETF The Internet Engineering Task Force (http://www.ietf.org) is an open international
community of network designers, operators, vendors, and researchers to develop and
maintain Internet architecture. Technical working groups issue working documents called
Internet-Drafts. The IETF publishes review versions of the drafts called requests for
comments (RFCs).

Internet A worldwide collection of interconnected networks using TCP/IP.
internetwork A collection of interconnected networks allowing communication between all devices
connected to any network in the collection.
IP Internet Protocol is a set of standards that enable different types of computers to
communicate with one another and exchange data through the Internet. IP provides the
appearance of a single, seamless communication system and makes the Internet a virtual
network.
IP address In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-
binary digit number that identifies each sender or receiver of information that is sent in
packets across the Internet. When you request an HTML page or send e-mail, the Internet
Protocol part of TCP/IP includes your IP address in the message (actually, in each of the
packets if more than one is required) and sends it to the IP address that is obtained by
looking up the domain name in the Uniform Resource Locator you requested or in the e-
mail address you're sending a note to. At the other end, the recipient can see the IP
address of the Web page requester or the e-mail sender and can respond by sending
another message using the IP address it received.
TCP/IP networks therefore route messages based on the destination IP address. An IP
address has two parts:
• The network address is assigned by IANA.
• A host address.
The Motorola Cellular Gateway NC800 network administrator assigns a host address to
each host connected to the Motorola Cellular Gateway NC800. This is done either via a
static IP address or automatically using its DHCP server. For a Class C network, the first 24
bits are the network address and the final 8 bits are the host address; in dotted-decimal
format it appears as network.network.network.host.
IPSec The Internet Protocol Security protocols are described in IETF authentication and
encryption standards for secure packet exchange over the Internet. IPSec consists of a
suite of protocols used to implement secure exchange of packets at the IP layer (i.e. OSI
layer 3). IPSec supports two basic modes: Transport and Tunnel. Transport encrypts the
payload of each packet, leaving the header untouched, while Tunnel mode encrypts both
the header and the payload and is therefore more secure.
ISM Bands
Industrial, scientific, and medicine bands - Radio frequency bands that the Federal
Communications Commission (FCC) authorized for wireless LANs. The ISM bands are
located at 902 MHz, 2.400 GHz, and 5.7 GHz.
ISO The International Organization for Standardization (http://www.iso.ch) is a worldwide
federation of national standards bodies from approximately 140 countries. ISO is a non-
governmental organization established in 1947 to promote the development of
standardization and related activities in the world with a view to facilitating the international
exchange of goods and services, and to developing cooperation in the spheres of
intellectual, scientific, technological, and economic activity.
ISP An ISP (Internet Service Provider) is a company that provides individuals and companies
access to the Internet and other related services such as Web site building and virtual
hosting. An ISP can serve IP addresses dynamically, or assign static (fixed) IP addresses to
individual computers.

equipment. They come in almost any color with the most common being red, green, yellow
and recently, blue.
loopback A test that loops the transmit signal to the receive signal. Usually the loopback test is
initiated on a network device. The test is used to verify a path or to measure the quality of a
signal on that path.
M
MAC The Media Access Control address is a unique, 48-bit value permanently saved in ROM at
the factory to identify each Ethernet network device. It is expressed as a sequence of 12
hexadecimal digits. Also called an Ethernet address, physical address, hardware address,
or NIC address.

media The various physical environments through which signals pass; for example, coaxial,
unshielded twisted-pair (UTP), or fiber-optic cable.
MHz Megahertz. One million cycles per second. A measure of radio frequency.
MRU The MRU (Maximum Receive Unit) sets the maximum number of bytes that PPP is capable
of receiving in one PPP packet. Generally, the bigger the better.
MTU The Maximum Transmission Unit is the largest amount of data that can be transmitted in
one discrete message on a given physical network. The MTU places an upper bound on the
size of a message that can be transferred by the network in a single frame. Messages
exceeding the MTU must be fragmented before transmission, and reassembled at the
destination.
multicast A data transmission sent from one sender to multiple receivers. See also broadcast and
unicast.

NAT Network Address Translation - An Internet standard that enables a local-area network
(LAN) to use one set of IP addresses for internal traffic and a second set of IP addresses
for external traffic. A NAT box located where the LAN meets the Internet makes all
necessary IP address translations. NAT provides some security
because the IP addresses of the LAN computers are invisible on the Internet.
NAPT Network Address Port Translation is the most common form of address translation between

Network layer Layer 3 in the OSI architecture that provides services to establish a path between open
systems. The network layer knows the address of the neighboring nodes, packages output
with the correct network address data, selects routes, and recognizes and forwards to the
transport layer incoming messages for local host domains.
NIC A network interface card converts computer data to serial data in a packet format that it
sends over the LAN. A NIC is installed in an expansion slot or can be built-in. Every
Ethernet NIC has a MAC address permanently saved in its ROM.

O
Omni-
directional
antenna
An antenna that provides a 360-degree transmission pattern. These types of antennas are
used when coverage in all directions is required.
OFDM Developed for wireless applications, Orthogonal Frequency Division Multiplexing
technology offers superior performance increased data rates and more reliable
transmissions than previous technologies, such as DSSS. OFDM is a scheme in which
numerous signals of different frequencies are combined to form a single signal for
transmission on the medium. OFDM works by breaking one high-speed data stream into a
number of lower speed data streams, which are then transmitted in parallel. Each lower
speed stream is used to modulate a sub carrier. Essentially, this creates a multi-carrier
transmission by dividing a wide frequency band or channel into a number of narrower
frequency bands or sub-channels. OFDM is also used for other applications, including
power line networking.
Open Systems
Authentication
The IEEE 802.11 default authentication method is a two-step process. First, the station
wanting to authenticate with another station sends an authentication management frame
containing the sending station's identity. The receiving station then sends back a frame
alerting whether it recognizes the identity of the authenticating station.
OSI The Open Systems Interconnection reference model is an illustrative model describing how
data moves from an application on the source host through a network to an application on
the destination host. It is a conceptual framework developed by ISO that is now the primary
model for intercomputer communications. OSI is a model only; it does not define a specific
networking interface.
P
packet The unit of data that is routed between the sender and destination on the Internet or other
packet-switched network. When data such as an e-mail message or other file is sent over
the Internet, IP on the sender divides the data into uniquely-numbered packets.The packet
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 102 of 110
header contains the source and destination IP addresses. The individual packets may travel
different routes. When all packets arrive at the destination, the IP at that end reassembles
the packets. The header and the data can vary in length. Packet and datagram are similar
in meaning.
Packet-
switched
A scheme to handle transmissions on a connectionless network such as the Internet. An
alternative is circuit-switched.
PCMCIA The Personal Computer Memory Card International Association sets international standards
for connecting peripherals to portable computers. Laptop computers typically have a
PCMCIA slot that can hold one or two PC Cards to provide features such as Ethernet
connectivity.

Physical layer Layer 1 in the OSI architecture. It provides services to transmit bits or groups of bits over a
transmission link between open systems. It entails the electrical, mechanical, and
handshaking procedures.
PING A network utility that tests host reachability by sending a small packet to the host and
waiting for a reply. If you PING a computer IP address and receive a reply, you know the
computer is reachable over the network. It also stands for Packet InterNet Groper.
port On a computer or other electronic device, a port is a socket or plug used to physically
connect it to the network or to other devices. In TCP/IP, a port is a number from 0 to 65536
used logically by a client program to specify a server program. Ports 0 to 1024 are reserved
POTS The plain old telephone service offered through the PSTN; basic analog telephone service.
POTS uses the lowest 4 kHz of bandwidth on twisted pair wiring.
PPP PPP (Point to Point Protocol) is a protocol for communication between computers using a
serial interface, typically a personal computer connected by phone line to a server.
PPPoE Point to Point Protocol over Ethernet.
PPTP Point-to-Point Tunneling Protocol encapsulates other protocols. It is a protocol that allows
corporations to extend their own corporate network through private “tunnels” over the public
Internet. Effectively, a corporation uses the wide-area network to create a large virtual
private network.
Private IP
address
An IP address assigned to a computer on the Motorola Cellular Gateway NC800 LAN by
the DHCP server on the Motorola Cellular Gateway NC800 for a specified lease time.
Private IP addresses are used by the Motorola Cellular Gateway NC800 LAN only; they are
invisible to devices on the Internet. See also public IP address.
protocol A formal set of rules and conventions for exchanging data. Different computer types (for
example PC, UNIX, or mainframe) can communicate if they support common protocols.
Proxy server A piece of software that sits between a client application (such as a Web browser) and the
Internet. It intercepts all traffic flowing between the two and analyzes them. This allows
proxy servers to do two important things. One is to boost Internet access speeds for groups
of users. Since the proxy server stores a "cache" of recently downloaded Web sites, any
user that tries to access a Web site that has recently been accessed by another user is
simply sent the cached version from the proxy server. The other important function is
filtering. A proxy server can be set up to filter all attempts by users to access specific Web
sites.
PSTN The public switched telephone network is the traditional circuit-switched, voice-oriented
telephone network. See also POTS.

Q, R
RFC Request for Comments published on the IETF or other websites. Many RFCs become
international standards.
RIP Routing Information Protocol - A common type of routing protocol. RIP bases its routing
path on the distance (number of hops) to the destination. RIP maintains optimum routing
paths by sending out routing update messages if the network topology changes. For
example, if a gateway finds that a particular link is faulty, it will update its routing table, and
then send a copy of the modified table to each of its neighbors.
RJ-11 The most common type of connector for household or office phones.
RJ-45 A connector for Cat 5 or Cat 5e cable, with 8 pins. It looks similar to a typical telephone wire
connector that only has 4 or 6 pins, but it is larger in size.
roaming A feature of some access points or gateways that allow users to move through a facility
while maintaining an unbroken connection to the LAN.
routing table A table listing available routes that is used by a gateway to determine the best route for a
packet.
RTS Request To Send.
S
scope The set of IP addresses that a DHCP server can lease to clients.
server A host computer that stores information and software programs used by other computers in
a network (it “serves” the programs and information to other computers). Examples of
services are file transfer, remote login and printing services.
Shared key
authentication
A type of authentication that assumes each station has received a secret shared key
through a secure channel independent from an 802.11 network. Stations authenticate
through shared knowledge of the secret key. Use of Shared Key authentication requires
implementation of the 802.11 Wireless Equivalent Privacy (WEP) algorithms.
SOHO Small Office Home Office
spectrum A specified range of frequencies used for transmission of electromagnetic signals.
spectrum
allocation
An allocation of portions of the available electromagnetic spectrum for specific services,
such as AM, FM, or personal communications.
SSID Service Set Identifier - An identification name that wireless devices use to make
connections. In order for wireless devices to communicate, they must all be set to the same
channel and they all must use the same SSID. For instance, if you are using an access
point to connect two computers using wireless devices, the access point and each of the
wireless devices must use the same SSID. Even if they are set to the same channel, they
cannot communicate unless the SSID is the same.
Stateful
inspection
A type of firewall that tracks each connection traversing all firewall interfaces to ensure
validity. In addition to examining the source and destination in the packet header based on
static rules, a stateful inspection firewall:
• Examines packet headers on context established by previous packets that
traversed the firewall
• Monitors the connection state and saves it in a table
• Closes ports until a connection to a specific port is requested
• May examine the packet contents up through the application layer to determine
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 104 of 110
more than just the source and destination
A stateful-inspection firewall is more advanced than a static filter firewall.
Static filter A type of firewall that examines the source and destination in the packet header based on
administrator-defined rules only.
Static IP
Address
A permanent IP address that is assigned to a host in a TCP/IP network. Normally, a static
IP address must be assigned manually. The opposite of dynamic IP address.
Static route A manually-defined route.
station IEEE 802.11b term for wireless client.
Subnet A network segment connected by hubs or repeaters. Subnets can stand alone or can be
connected to other subnetworks onto a larger network. When subnetting is used, the host
portion of the IP address is divided into a subnet and host number. Hosts and gateways use
the subnet mask to identify the bits used for the network and subnet number.
Subnet mask The method used for splitting IP networks into a series of subgroups, or subnets. The mask
is a binary pattern that is logically ANDed with the IP address to turn part of the host ID
address field into a field for subnets. A gateway routes packets using the network prefix and
the subnet number part of the IP address.
switch A switch is more sophisticated than a hub and connects one user to another without
blocking access of other users. The switch improves throughput because of the smaller
resulting collision domains. Users don't have to wait until others are finished before sending
data.
SYSLOG A de-facto UNIX standard for logging system events.
T
TCP Transmission Control Protocol - A method (protocol) used along with the IP (Internet
Protocol) to send data in the form of message units (datagram) between network devices
over a LAN or WAN. Transmission Control Protocol on OSI transport layer four, provides
reliable transport over the network for data transmitted using IP (network layer three). It is
an end-to-end protocol defining rules and procedures for data exchange between hosts on
top of connectionless IP. TCP uses a timer to track outstanding packets, checks errors in
incoming packets, and retransmits packets if requested.TCP is known as a "connection
oriented" protocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
TCP/IP Transmission Control Protocol/Internet Protocol - The basic communication language or set
of protocols for communications over a network (developed specifically for the Internet).
TCP/IP defines a suite or group of protocols and not only TCP and IP.
TFTP Trivial File Transfer Protocol is a scaled down version of the well known FTP protocol
commonly used for file transfer over the Internet. Being a scaled down protocol, it is ideal
for use in an embedded environment such as a wireless gateway. It is used to upload new
firmware to the Motorola Cellular Gateway NC800.
Transparent
bridging
A method to enable all hosts on the wired Ethernet LAN and IEEE 802.11b wireless LAN to
communicate as if they were all connected to the same physical network.
Transport
layer
Layer of the OSI concerned with protocols for error recognition and recovery. This layer
also regulates information flow.
TTL The time to live is the number of gateways (or hops) a packet can traverse before being
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 105 of 110
discarded. When a gateway processes a packet, it decreases the TTL by 1. When the TTL
reaches zero, the packet is discarded.
tunnel To place packets inside other packets to send over a network. The protocol of the enclosing
packet is understood by each endpoint, or tunnel interface, where the packet enters and
exits the network. VPNs rely on tunneling to create a secure network.Tunneling requires the
following protocol types:
• A carrier protocol, such as TCP, used by the network that the data travels over
• An encapsulating protocol, such as IPSec, L2F, L2TP, or PPTP, that is wrapped
around the original data
• A passenger protocol, such as IP, for the original data.
U
UDP User Datagram Protocol - A method (protocol) used along with the IP (Internet Protocol) to
send data in the form of message units (datagrams) between network devices over a LAN
or WAN. UDP is an OSI layer four protocol, while IP is a layer three protocol. UDP is known
as a “connection-less” protocol due to NOT requiring the receiver of a packet to return an
acknowledgment of receipt to the sender of the packet (as opposed to TCP).
unicast A point-to-point data transmission sent from one sender to one receiver. This the normal
way you access websites. See also broadcast and multicast.
URL Universal Resource Locator - URLs are the Internet equivalent of addresses. How do they
work? Like other types of addresses, they move from the general to the specific (from zip
code to recipient, so to speak). Take this URL, for example:
www.motorola.com/CellularGateway/index.html. First you have the protocol: http:/ then the
server address or domain: /www.motorola.com and finally the directory:
/CellularGateway/ in which the file index.html resides.
USB Universal Serial Bus is a computer interface for add-on devices such as printers, scanners,
mice, modems, or keyboards. USB supports data transfer rates of 12 Mbps and plug-and-
play installation. You can connect up to 127 devices to a single USB port.
UTP Unshielded Twisted Pair. Also referred to as 10BASE-T or 100BASE-T network cable.
V
VLAN A virtual local area network is group of devices on different LAN segments that are logically
configured to communicate as if they are connected to the same wire.
VoIP Voice over Internet Protocol is a method to exchange voice, fax, and other information over
the Internet. Voice and fax have traditionally been carried over traditional telephone lines of
the PSTN using a dedicated circuit for each line. VoIP enables calls to travel as discrete
data packets on shared lines. VoIP is an important part of the convergence of computers,
telephones, and television into a single integrated information network.
VPN Virtual Private Network - Virtual Private Networks allows computers to use the public
Internet backbone as a channel for private data communication. With encryption and
encapsulation technology, a VPN creates a private passageway (tunnel) through the
Internet. VPNs allow remote offices, company road warriors, and even businesses'
customers to use the Internet, rather than pricey private lines, to reach company networks.
A VPN connection provides security and performance similar to a dedicated link (for
example, a leased line), but at much lower cost.

WAN Wide Area Network. A wide-area network provides a connection over a large geographic
area, such as a country or the whole world. The bandwidth depends on need and cost, but
is usually much lower than for a LAN.
WAP Wireless Access Point or Wireless Access Protocol. See also access point.
WECA Wireless Ethernet Compatibility Alliance - An alliance of companies throughout the world
that promote the use of the IEEE 802.11 standard in wireless technology. It is a trade
organization that works to ensure that all wireless IEEE 802.11b Wi-Fi devices such as
computer cards, laptops, air gateways, PDAs, etc. can communicate with each other.
WEP Wired Equivalent Privacy encryption protects the privacy of data transmitted over a wireless
LAN. WEP uses keys to encrypt and decrypt transmitted data. The access point must
authenticate a client before it can transfer data to another client. WEP is part of IEEE
802.11b. It is based on a 64- or 128- bit shared key algorithm, as described in the IEEE
802.11b standard.
WEP network
key
A network key is a key used for network encryption under the WEP algorithm. Under
802.11, a wireless station can be configured with up to four network keys, with the key
index values being 1, 2, 3, and 4. When an access point or a wireless station transmits an
encrypted message using a key that is stored in a specific key index, the transmitted
message indicates the key index that was used to encrypt the message body. The receiving
access point or wireless station can then retrieve the key that is stored at the key index and
use it to decode the encrypted message body.
Wi-Fi Wireless Fidelity - The IEEE 802.11 High Rate Standard used in wireless technology. The
Wi-Fi (pronounced y-phi) seal of approval assures the end customer of interoperability with
other network cards and access points which also bear the Wi-Fi logo. Wi-Fi is the brand
name applied to products supporting IEEE 802.11 or WLAN.
WINS Short for Windows Internet Naming Service, a system that determines the IP address
http://www.webopedia.com/TERM/W/IP_address.html associated with a particular network
computer. This is called name resolution. WINS supports network client and server
computers running Windows and can provide name resolution for other computers with
special arrangements. Determining the IP address for a computer is a complex process
when DHCP servers assign IP addresses dynamically. For example, it is possible for DHCP
to assign a different IP address to a client each time the machine logs on to the network.
WINS uses a distributed database that is automatically updated with the names of
computers currently available and the IP address assigned to each one. DNS is an
alternative system for name resolution suitable for network computers with fixed IP
addresses.
Wireless
network
interface
Couples the digital signal from the end-user appliance to the wireless medium, which is air.
WLAN Wireless Local Area Network - A group of computers and associated devices that
communicate with each other wirelessly. Wireless LANs are used increasingly in both home
and office environments.
WWW World Wide Web - The Internet's multimedia service containing countless areas of
information, documentation, entertainment, as well as business and personal home
pages. It is an interface to the Internet that you use to navigate and hyperlink to information.

Appendix D: Upgrading the Motorola Cellular Gateway NC800
firmware using TFTP
Trivial File Transfer Protocol (TFTP) is a scaled down version of the well-known FTP protocol commonly used
for file transfer over the Internet. Being a scaled down protocol, it is ideal for use in an embedded environment
such as a wireless gateway. It offers an alternative method of firmware upgrading to the web-based method.
The Motorola Cellular Gateway NC800 accepts TFTP file transfers only during the first three seconds after
boot up.
To upgrade the Motorola Cellular Gateway NC800’s firmware using TFTP follow these steps:
o Open a TFTP compatible client on a PC connected to the primary LAN of the Gateway. The PC must be
configured with a static IP address on the same subnet as the Gateway (The user must be able to
successfully ping the Gateway’s primary LAN IP address from the PC).
o Specify the Gateway’s Primary LAN IP address in the TFTP client.
o Specify binary mode for file transfer.
o Type PUT firmware.trx where firmware.trx is the full path to the new firmware file.
o Reset the Motorola Cellular Gateway NC800 by pressing the Reset button at the back of the Motorola
Cellular Gateway NC800.
o Hit the Enter button to issue the PUT firmware.trx command.
o The TFTP client reports the progress / result of the file transfer.
o If successful, the Motorola Cellular Gateway NC800 reboots using the new firmware image after
approximately 30 seconds (it first writes the new image to FLASH once it has been transferred).
