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.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 39 of 110 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. Special Buttons: Refreshes the list to the most recently assigned IP addresses
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 42 of 110 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. .
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 45 of 110 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. Motorola Cellular GatewayCDMA AntennaPDAWireless LAN devices192.168.1.100192.168.1.1192.168.10.10 192.168.10.11 192.168.10.12192.168.1.10192.168.1.11192.168.1.12192.168.10.1RouterEthernet 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.
Motorola Cellular Gateway NC800 User Guide Version 2.0 Page 50 of 110 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 www.motorola.com.

Valid values are Default, Auto and 1 & 2 Mbps. • RTS Threshold – This setting should remain at its default of 2347 which means that RTS mechanism is not used . If you encounter inconsistent data flow, you may make small changes to this value in the 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 Gateway NC800 to synchronize a wireless network. A beacon includes the wireless LAN service area, the IP address, the broadcast destination address, a time stamp, Delivery Traffic Indicator Maps and the Traffic Indicator Message (TIM). • Preamble Type – Sets the preamble type used for 802.11b only.

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.
