Table 11 - Data connection item details

Connecting to the mobile broadband network

The router supports the configuration of up to six APN profiles; these profiles allow you to configure the settings that the router will use to connect to the broadband network and switch easily between different connection settings.

Manually configuring a connection profile

To manually configure a connection profile:

1. Click the Edit button corresponding to the Profile that you wish to modify. The data connection profile settings page is displayed.

Figure 15 - Data connection profile settings

1. Click the Profile toggle key to turn the profile on. Additional settings appear.

Data connection profile settings

Profile routing settings

You may route only particular traffic via this connection profile by specifying the network address and mask below of the destination network. Blank values will route all traffic via this profile. Please leave these settings blank if you are unsure.

Figure 16 - Data connection settings - Profile turned on

1. In the Profile name field, enter a name for the profile. This name is only used to identify the profile on the router.

2. Ensure that the Automatic APN selection toggle key is set to off. If it is not, click it to toggle it to the off position.

3. In the APN field, enter the APN Name (Access Point Name) and if required, use the Username and Password fields to enter your login credentials.

4. Next to Authentication type, select either CHAP or PAP depending on the type of authentication used by your provider.

5. The Reconnect delay field specifies the number of seconds to wait between connection attempts. The default setting of 30 seconds is sufficient in most cases but you may modify it to wait up to 65535 seconds if you wish.

6. The Reconnect retries field specifies the number of times to attempt a network connection if the router fails to establish a connection. It is set to 0 by default which causes the router to attempt to reconnect indefinitely.

7. The Metric value is used by router to prioritise routes (if multiple are available) and is set to 20 by default. This value is sufficient in most cases but you may modify it if you are aware of the effect your changes will have on the service.

8. The MTU field allows you to modify the Maximum Transmission Unit used on the connection. Do not change this unless instructed to by your carrier.

9. Use the NAT Masquerading toggle key to turn NAT Masquerading on or off. NAT masquerading, also known simply as NAT is a common routing feature which allows multiple LAN devices to appear as a single WAN IP via network address translation. In this mode, the router modifies network traffic sent and received to inform remote computers on the internet that packets originating from a machine behind the router actually originated from the WAN IP address of the router's internal NAT IP address. This may be disabled if a framed route configuration is required and local devices require WAN IP addresses.

10. Click the Save button when you have finished entering the profile details.

Confirming a successful connection

After configuring the packet data session, and ensuring that it is enabled, click on the Status menu item at the top of the page to return to the Status page. When there is a mobile broadband connection, the WWAN section is expanded showing the details of the connection and the Status field displays Connected. To see details on the connected session, you can click the Show data usage button.

Figure 17 - WWAN connection status section

Transparently bridging the mobile broadband connection via PPPoE

If desired, you can have a client device connected to the Ethernet port initiate the mobile broadband connection using a PPPoE session. This is particularly useful in situations where you wish to provide Wireless WAN data access to an existing router which you want to have full public WAN IP access and have control over routing functionality.

To enable transparent bridging via PPPoE:

1. Click the Networking menu item from the top menu bar.
2. On the Data connection page, click the Transparent bridge (PPPoE) toggle key so that it is ON.

Data connection

Transparent bridge (PPPoE)

OFF

In this mode the unit acts as an Ethernet Bridge instead of as an IP Router. This is facilitated by PPPoE which forwards the WAN IP/DNS information to a downstream LAN device and facilitates transparent network connectivity. To use this feature, you need to initiate a PPPoE client connection from a downstream device (such as a Ethernet Router or computer) which is then accepted by the router. The router operates a PPPoE server and will activate a PDP context using the username/password from the PPPoE client connection and the APN configured on this page. This allows control over the PDP context activation by the downstream device. Once enabled in this mode, some router functionality will no longer be applicable and will cease to function (e.g Connect on demand, routing, VPN, TR-069, Router firewall, remote access, and others). Only a single downstream device is permitted Wireless WAN connectivity and all traffic is forwarded to that device. Please note in this mode, the downstream device is responsible for all network security as the built-in firewall has no effect.

Transparent bridge mode configuration

Figure 18 - Transparent bridge configuration

1. In the APN name field, enter the APN that you wish to use for the mobile broadband connection.
2. (Optional) In the Service name field, enter a name that allows you to easily identify the connection.
3. Click the Save button to confirm the settings.
4. Click the Status menu item from the top menu bar to see the transparent bridging status.

Figure 19 - Transparent bridge mode status

1. Next you must configure your downstream device connected via Ethernet to the NTC-140W to initiate a network connection using a PPPoE client. The username and password used by the downstream device for the PPPoE session will be passed on and used by the NTC-140W as the packet data (PDP) context authentication settings.

Connect on demand

The Connect on demand feature keeps the Packet Data Protocol (PDP) context deactivated by default while making it appear to locally connected devices that the router has a permanent connection to the mobile broadband network. When a packet of interest arrives or an SMS wake-up command is received, the router attempts to establish a mobile broadband data connection. When the data connection is established, the router monitors traffic and terminates the link when it is idle.

Note: When interesting packets arrive, the recovery time for the wireless WAN connection is approximately 20-30 seconds.

Configuring Connect on demand

To configure Connect on demand:

1. Click the Networking menu item from the top menu bar.
2. On the Connect on demand page, click the Connect on demand toggle key so that it is ON. Extra options appear. See the following sub-sections for further instructions.

Connect on demand

The connect on demand feature keeps the PDP context deactivated by default while making it appear that the router has permanent connection to WWAN and locally connected devices. When interesting packets arrive or an SMS wake-up command is received, the router will attempt to establish a WWAN data connection. The router will monitor traffic once the data connection is established and will terminate it when the link is idle.

In some situations, you may wish to have the internet connection disabled except at times when outbound traffic to a particular external host's port or group of ports is sent to the router. To use this feature, click Enable dial port filter and enter the port number or list of port numbers separated by commas. When you select this option, all outbound ICMP/TCP/UDP packets to any remote host on the specified port(s) will trigger the connection to dial. Note that when this feature is enabled, the options to ignore specific packet types are not available.

Data activity triggered connection

Connect only when traffic appears to these UDP/TCP destination ports. You can specify multiple ports by separating them with a comma (eg 21, 23, 53).

Figure 21 - Connect on demand - Data activity triggered connection

You can allow Microsoft network awareness (NCSI) traffic through but if you prefer that they do not trigger the connection, click the Ignore Microsoft network awareness (NCSI) traffic toggle key to set it to ON.

Ignore Microsoft network awareness (NCSI) traffic

Figure 22 - Connect on demand - Ignore NCSI traffic

Excluding certain packet types from triggering the connection to dial

Depending on your environment, you might prefer to exclude certain types of traffic passing through the router from triggering the data connection. You can tell the router to ignore outbound TCP, UDP or ICMP packets. When any of these options are checked the router will not dial a connection when that type of outbound destined data packet reaches the router from a locally connected device.

Connect on data activity except when activity matches these IP protocols

Figure 23 - Connect on demand - Excluding IP protocols

Excluding certain application types from triggering the connection to dial

Some devices may generate general traffic as a part of normal operation which you may not want to trigger the data connection. You can set the router to ignore Domain Name System (DNS), Network Time Protocol (NTP) or Microsoft network awareness (NCSI) traffic from devices behind the router. When you check the box for these options, it tells the router to ignore the request from that application type and will not dial a connection when this data type is received.

Setting timers for connection and disconnection

The router has a number of timer settings which let you determine when a connection is dialled and when it is disconnected.

Figure 25 - Connect on demand - Connect and disconnect timers

OPTION	DESCRIPTION
On data activity, stay online for at least	When traffic as per the configured settings above appear, the router will either continue to stay online, or dial a connection and will not disconnect it for the specified time period (min. 1 minute, max. 1 hour). This timer is continuously reset throughout the duration of a dial-up session, whenever data activity is detected matching the rules above.
After connecting, stay online for at least	This timer configures the router to not hang-up the connection for the specified time period after initially dialling the connection. This setting cannot be less than the keep online period above. This timer affects the connection only once per dial up session, at the beginning of the session.
After hanging up, don't redial for	After a connection has been disconnected, you can tell the router to rest for a period of time before re-dialling.
Disconnect regardless of traffic after	Forces the router to disconnect the connection regardless of the traffic passing through it. The default setting is never.
Connect regularly, every / Randomise connect frequency by up to	If you want to have the router dial a connection at regular intervals, use Connect regularly, every to specify the interval between dials. Setting this to never effectively disables this option.The router also features the ability to randomise the time at which the first dial action is performed. This is useful in situations such as where you have numerous routers in an area where a power outage has occurred. Setting a random dial time helps to reduce network congestion when all the routers are powered on so they do not all try to connect simultaneously.When Connect regularly, every is set to at least 2 minutes, you are able to configure the router to randomise the time it begins to dial. The randomised dial timer only affects the initial dial after the unit powers on or after the settings are saved. For example, if you configure the router to dial every 2 minutes with a randomised dial starting time of 1 minute, the router waits for the Connect regularly, every time (2 minutes) and then randomly selects a time less than or equal to the Randomise connect frequency by up to time (1 minute). After the randomly selected time has elapsed, the router dials the connection. After the first dial, the router dials the connection every 2 minutes, ignoring the Randomise connect frequency by up to time.

Table 12 - Connect on demand - Connect and disconnect timers descriptions

Verbose mode

The router provides the option of logging all the data activity which matches the settings for the Connect on demand feature for advanced troubleshooting purposes. To enable the logging of the Connect on demand feature, click the Enable verbose mode toggle key to switch it ON. See the System log section for more information.

Figure 26 - Connect on demand - Verbose logging configuration

Manually connecting/disconnecting

There may be times when you need to either force a connection to be made or force a disconnection manually. You can use the Manual connect and Manual disconnect buttons to do this whenever necessary. The online status of the connection is displayed above the buttons.

Online / Offline control

Online status Disabled

Figure 27 - Connect on demand - Online/Offline control

When you have finished configuring the options for the Connect on demand feature, click the Save button at the bottom to save your changes.

SMS Wake up

The router can also be woken up by means of an SMS message using the SMS diagnostics feature by sending an executable wakeup command via SMS. See the Diagnostics section for details on using the SMS Wake up function.

SIM Management

The SIM management page allows you to specify the primary SIM to use in the case where you have a soldered down SIM card and a SIM inserted into the SIM tray. To change the preference of the SIMs, use the arrow button to the right of SIM2 to switch priorities and click the Save button.

Figure 28 - SIM Management

Operator settings

The Operator settings page enables you to select which frequency band you will use for your connection and enables you to scan for available network operators in your area.

Figure 29 - Band settings

Note: In order to change the operator's band settings, the data connection must be disabled. When you access this page, you are prompted to disable the data connection if it is already active.

You may want to do this if you're using the router in a country with multiple frequency networks that may not all support High Speed Packet Access (HSPA). You can select the router to only connect on the network frequencies that suit your requirements.

Use the Change band drop down list to select the band you wish to use.

The following band settings options are available:

It is not necessary to change the default setting of All bands in most cases. In fact, locking to a particular band can cause connection difficulties if the device is moved to a location where the forced band selection is no longer available.

When All bands is selected, the router attempts to find the most suitable band based on the available networks for the inserted SIM card.

The "2G all", "WCDMA all", "LTE all", "3G/2G all" and "LTE/3G all" options allow you to force the device to lock to those particular networks only.

Click the Save button to save and apply your selection.

Operator settings

The operator settings feature allows you perform a scan of available networks, and to optionally lock to a particular network returned by the network scan. To scan for available networks, set the Select operator mode from automatic to Manual then click the scan button. This operation can take a few minutes and requires that the packet data session be disconnected prior to scanning.

Figure 30 - Operator settings

A list of the detected cellular service carriers in your area is displayed.

Figure 31 - Detected operator list

Select the most appropriate service from the list shown and click Apply.

When Select operator mode is set to Automatic, the router selects the most appropriate operator based on the inserted SIM card. This is the default option and is sufficient for most users.

SIM security settings

The SIM security settings page can be used for authenticating SIM cards that have been configured with a security PIN.

Unlocking a PIN locked SIM

If the SIM card is locked, you will receive a notice when you access the Status page after which you will be directed to the PIN settings page to enter the PIN. The PIN settings page lists the status of the SIM at the top of the page.

If you are not redirected to the PIN settings page, to unlock the SIM:

a) Click on the Networking menu from the top menu bar, and then click SIM security settings.

Figure 32 - SIM security settings - SIM PIN locked

b) Enter the PIN in the Current PIN field and then enter it again in the Confirm current PIN field to confirm the PIN.
c) If you are placing the router in a remote, unattended location, you may wish to check the Remember PIN option. This feature allows the router to automatically send the PIN to the SIM each time the SIM asks for it (usually at power up). This enables the SIM to be PIN locked (to prevent unauthorised re-use of the SIM elsewhere), while still allowing the router to connect to the cellular service.

When this feature is enabled, the PIN you enter when setting the Remember PIN feature is encrypted and stored locally on the router. The next time the SIM asks the router for the PIN, the router decrypts the PIN and automatically sends it to the SIM without user intervention.

When this feature is disabled and the SIM is PIN locked and the PIN must be manually entered via the router's configuration interface. In situations where the router will be unattended, this is not desirable.

Note: Select Remember PIN if you do not want to enter the PIN code each time the SIM is inserted.

d) Click the Save button. If successful, the router displays the following screen:

Unlocking a PUK locked SIM

After three incorrect attempts at entering the PIN, the SIM card becomes PUK (Personal Unblocking Key) locked and you are requested to enter a PUK code to unlock it.

Note: To obtain the PUK unlock code, you must contact your service provider.

You will be issued a PUK to enable you to unlock the SIM and enter a new PIN. Enter the new PIN and PUK codes. Click the Save button when you have finished entering the new PIN and PUK codes.

Figure 37 - SIM security - SIM PUK locked

LAN

LAN configuration

The LAN configuration page is used to configure the LAN settings of the router and to enable or disable DNS Masquerading.

Figure 38 – LAN configuration settings

The default IP of the LAN port is 192.168.1.1 with subnet mask 255.255.255.0. To change the IP address or Subnet mask, enter the new IP Address and/or Subnet mask and click the Save button.

Note: If you change the IP address, remember to reboot the router and enter the new IP address into your browser address bar.

DNS masquerading

DNS masquerading allows the router to proxy DNS requests from LAN clients to dynamically assigned DNS servers. When enabled, clients on the router's LAN can then use the router as a DNS server without needing to know the dynamically assigned cellular network DNS servers.

With DNS masquerading ON, the DHCP server embedded in the NTC-140W Series router hands out its own IP address (e.g. 192.168.1.1) as the DNS server address to LAN clients. The downstream clients then send DNS requests to the NTC-140W Series router which proxies them to the upstream DNS servers.

With DNS masquerading OFF, the DHCP server hands out the upstream DNS server IP addresses to downstream clients directly, so that downstream clients send DNS requests directly to the upstream DNS servers without being proxied by the NTC-140W Series router.

You may also override the DNS Masquerading option by specifying custom DNS Server IP addresses in the DHCP Server configuration mentioned in the next section of this guide. In this case the DHCP server assigns downstream devices the manually configured addresses and the DNS Masquerading option is ignored.

In most cases, it is not necessary to disable DNS masquerading but if you need to, click the DNS masquerading toggle key to turn it OFF and then click the Save button.

DHCP

The DHCP page is used to adjust the settings used by the router's built in DHCP Server which assigns IP addresses to locally connected devices.

DHCP relay configuration

In advanced networks configurations where the NTC-140W Series router should not be responsible for DHCP assignment, but instead an existing DHCP server is located on the Wireless WAN or LAN connections, the clients behind the NTC-140W Series router are able to communicate with the DHCP server when DHCP relay is enabled. This enables the NTC-140W Series router to accept client broadcast messages and to forward them onto another subnet.

To configure the router to act as a DHCP relay agent click the DHCP relay toggle key to turn it ON and enter the DHCP server address into the DHCP server address field. DHCP relay is disabled by default.

Figure 39 - DHCP relay configuration

DHCP configuration

You can manually set the start and end address range to be used to automatically assign addresses within, the lease time of the assigned address, the default domain name suffix, primary and secondary DNS server, the primary and secondary WINS server, as well as the advanced DHCP settings such as NTP, TFTP and Option 150/Option 160 (VoIP options).

DHCP option 160	This is used to configure Polycom IP phones. When a Polycom IP phone starts, if it is not pre-configured with the IP address and TFTP address, it sends a request to the DHCP server to obtain this information. Specify the string which will be sent as a reply to the option 160 request.

Enter the desired DHCP options and click the Save button.

Routing

Static

Static routing is the alternative to dynamic routing used in more complex network scenarios and is used to facilitate communication between devices on different networks. Static routing involves configuring the routers in your network with all the information necessary to allow the packets to be forwarded to the correct destination. If you change the IP address of one of the devices in the static route, the route will be broken.

Figure 56 - Static routing list

Some routes are added by default by the router on initialization such as the Ethernet subnet route for routing to a device on the Ethernet subnet.192

Adding Static Routes

To add a new route to the static routing list, click the +Add button. The Static routes page appears.

1. In the Route name field, type a name for the route so that it can be identified in the static routing list.
2. From the Network interface drop down list, select the interface for which you would like to create a static route.
3. In the Destination IP address field, enter the IP address of the destination of the route.
4. In the IP subnet mask field, enter the subnet mask of the route.
5. In the Gateway IP address field, enter the IP address of the gateway that will facilitate the route.
6. In the Metric field enter the metric for the route. The metric value is used by the router to prioritise routes. The lower the value, the higher the priority. To give the route the highest priority, set it to 0.
7. Click the Save button to save your settings.

RIP

RIP (Routing Information Protocol) is used for advertising routes to other routers. Thus all the routes in the router's routing table will be advertised to other nearby routers. For example, the route for the router's Ethernet subnet could be advertised to a router on the PPP interface side so that a router on this network will know how to route to a device on the router's Ethernet subnet. Static routes must be added manually according to your requirements. See Adding Static Routes.

Note: Some routers will ignore RIP.

Redundancy (VRRP) configuration

Virtual Router Redundancy Protocol (VRRP) is a non-proprietary redundancy protocol designed to increase the availability of the default gateway servicing hosts on the same subnet. This increased reliability is achieved by advertising a "virtual router" (an abstract representation of master and backup routers acting as a group) as a default gateway to the host(s) instead of one physical router. Two or more physical routers are then configured to stand for the virtual router, with only one doing the actual routing at any given time. If the current physical router that is routing the data on behalf of the virtual router fails, an arrangement is made for another physical router to automatically replace it. The physical router that is currently forwarding data on behalf of the virtual router is called the master router.

Master routers have a priority of 255 and backup router(s) can have a priority between 1 and 254.

A virtual router must use 00-00-5E-00-01-XX as its (MAC) address. The last byte of the address (XX) is the Virtual Router Identifier (VRID), which is different for each virtual router in the network. This address is used by only one physical router at a time, and is the only way that other physical routers can identify the master router within a virtual router.

Figure 6.1 - VRRP configuration

To configure VRRP, configure multiple devices as follows and connect them all via an Ethernet network switch to downstream devices.

1. Click the Redundancy (VRRP) toggle key to activate VRRP.
2. In the Virtual ID field, enter an ID between 1 and 255. This is the VRRP ID which is different for each virtual router on the network.
3. In the Router priority field, enter a value for the priority – a higher value is a higher priority.
4. The Virtual IP address field is used to specify the VRRP IP address – this is the virtual IP address that both virtual routers share.
5. Click the Save button to save the new settings.

Note: Configuring VRRP changes the MAC address of the Ethernet port and therefore if you want to resume with the web configuration you must use the new IP address (VRRP IP) or on a command prompt type: arp -d (i.e. arp -d 192.168.1.1) to clear the arp cache.(old MAC address).

Port Forwarding

The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the router.

Figure 62 – Port forwarding list

The purpose of the port forwarding feature is to allow mapping of inbound requests to a specific port on the WAN IP address to a device connected on the Ethernet interface.

Adding a port forwarding rule

To create a new port forwarding rule:

1. Click the +Add button. The port forwarding settings screen is displayed.
2. Use the Protocol drop down list to select the type of protocol you want to use for the rule. The protocols selections available are TCP, UDP and All.
3. In the Source IP Address field, enter a "friendly" address that is allowed to access the router or a wildcard IP address (0.0.0.0) that allows all IP addresses to access the router.
4. The Source Port Range (From) and (To) fields are used to specify the port(s) on the source side that are to be forwarded. This allows you to send a range of consecutive port numbers by entering the first in the range in the (From) field and the last in the range in the (To) field. To forward a single port, enter the port in the (From) field and repeat it in the (To) field.
5. In the Destination network address field, enter the IP address of the client to which the traffic should be forwarded.
6. The Destination Port Range (From) and (To) fields are used to specify the port(s) on the destination side that are to be forwarded. If the Source port range specifies a single port then the destination port may be configured to any port. If the Source port range specifies a range of port numbers then the Destination port range must be the same as the Source port range.
7. Click the Save button to confirm your settings.

Figure 63 - Port forwarding settings

To delete a port forwarding rule, click the ✗ button on the Port forwarding list for the corresponding rule that you would like to delete.

DMZ

The Demilitarized Zone (DMZ) allows you to configure all incoming traffic on all protocols to be forwarded to a selected device behind the router. This feature can be used to avoid complex port forwarding rules, but it exposes the device to untrusted networks as there is no filtering of what traffic is allowed and what is denied.

The DMZ configuration page is used to specify the IP Address of the device to use as the DMZ host.

Figure 64 - DMZ configuration

1. Click the DMZ toggle key to turn the DMZ function ON.
2. Enter the IP Address of the device to be the DMZ host into the DMZ IP Address field.
3. Click the Save button to save your settings.

Router firewall

The Router firewall page is used to enable or disable the in-built firewall on the router. When enabled, the firewall performs stateful packet inspection on inbound traffic from the wireless WAN and blocks all unknown services, that is, all services not listed on the Services configuration page of the router.

With respect to the other Routing options on the Networking page, the firewall takes a low priority. The priority of the firewall can be described as:

DMZ > MAC/IP/Port filtering rules > MAC/IP/Port filtering default rule > Router firewall rules

In other words, the firewall is of the lowest priority when compared to other manual routing configurations. Therefore, a MAC/IP/Port filtering rule takes priority in the event that there is a conflict of rules. When DMZ is enabled, MAC/IP/Port filtering rules and the router firewall are ignored but the router will still honour the configuration of the Remote router access control settings listed under Administration Settings.

Figure 65 - Router firewall toggle key

MAC / IP / Port filtering

The MAC/IP/Port filter feature allows you apply a policy to the traffic that passes through the router, both inbound and outbound, so that network access can be controlled. When the filter is enabled with a default rule of "Accepted", all connections will be allowed except those listed in the "Current MAC / IP / Port filtering rules in effect" list. Conversely, when the default rule is set to "Dropped", all connections are denied except for those listed in the filtering rules list.

Figure 66 - MAC / IP / Port filtering

Note: When enabling MAC/IP/Port filtering and setting the default rule to "Dropped", you should ensure that you have first added a filtering rule which allows at least one known MAC/IP to access the router, otherwise you will not be able to access the user interface of the router without resetting the router to factory default settings.

Creating a MAC / IP / Port filtering rule

To create a filtering rule:

1. Click the MAC / IP / Port filtering toggle key to switch it to the ON position.
2. Using the Default rule (inbound/forward) drop down list, select the default action for the router to take when traffic reaches it. By default, this is configured to Accepted. If you change this to Dropped, you should first configure a filter rule that allows at least one device access to the router, otherwise you will effectively be locked out of the router.
3. Click the Save button to confirm the default rule.
4. In the Current MAC / IP / Port filtering rules in system section, click the +Add button.

Figure 67 - Current MAC / IP/ Port filtering rules in effect

1. Enter the details of the rule in the section that is displayed and click the Save button.

VPN

A Virtual Private Network (VPN) is a tunnel providing a private link between two networks or devices over a public network. Data to be sent via a VPN needs to be encapsulated and as such is generally not visible to the public network.

The advantages of a VPN connection include:

Data Protection
Access Control
Data Origin Authentication
Data Integrity

Each VPN connection has different configuration requirements. The following pages detail the configuration options available for the different VPN connection types.

Note: The following descriptions are an overview of the various VPN options available. More detailed instructions are available in separate whitepapers on the NetComm Wireless website.

IPSec

IPSec operates on Layer 3 of the OSI model and as such can protect higher layered protocols. IPSec is used for both site to site VPN and Remote Access VPN. The NTC-140W Series router supports IPsec end points and can be configured with Site to Site VPN tunnels with third party VPN routers.

5. From the Authentication type drop down list, select the Authentication type used on the server. If you do not know the authentication method used, select any and the router will attempt to determine the correct authentication type for you. There are 5 authentication types you can choose from:

CHAP – uses a three way handshake to authenticate the identity of a client.
MS-CHAP v1 – This is the Microsoft implementation of the Challenge Handshake Authentication Protocol for which support was dropped in Windows® Vista.
MS-CHAP v2 - This is the Microsoft implementation of the Challenge Handshake Authentication Protocol which was introduced in Windows® NT 4.0 and is still supported today.
PAP – The Password Authentication Protocol uses a password as a means of authentication and as such, is commonly supported. PAP is not recommended because it transmits passwords unencrypted and is not secure.
EAP – Extensible Authentication Protocol. An Authentication protocol commonly used in wireless networks.

1. The metric value helps the router to prioritise routes and must be a number between 0 and 65535. The default value is 30 and should not be modified unless you are aware of the effect your changes will have.

2. The Use peer DNS option allows you to select whether the remote clients will use the Domain Name Server of the PPTP server. Click the toggle key to set this to ON or OFF as required.

3. NAT masquerading allows the router to modify the packets sent and received to inform remote computers on the internet that packets originating from a machine behind the router actually originated from the WAN IP address of the router's internal NAT IP address. Click the toggle key to switch this to the ON position if you want to use this feature.

4. Set default route to PPTP sets all outbound data packets to go out through the PPTP tunnel. Click the toggle key to switch this to the ON position if you want to use this feature.

5. The Verbose logging option sets the router to output detailed logs regarding the PPTP connection in the System Log section of the router interface.

6. The Reconnect delay is the time in seconds that the router will wait before attempting to connect to the PPTP server in the event that the connection is broken. The minimum time to wait is 30 seconds so as to not flood the PPTP server with connection requests, while the maximum time to wait is 65335 seconds.

7. The Reconnect retries is the number of connection attempts that the router will make in the event that the PPTP connection goes down. If set to 0, the router will retry the connection indefinitely, otherwise the maximum number of times to retry cannot be greater than 65335.

8. Click the Save button to save the changes. The VPN will attempt to connect after your click Save. Click the Status button at the top left of the interface to return to the status window and monitor the VPN's connection state.

GRE tunnelling

The Generic Route Encapsulation (GRE) protocol is used in addition to Point-to-Point Tunnelling Protocol (PPTP) to create VPNs (virtual private networks) between clients and servers or between clients only. Once a PPTP control session establishes the VPN tunnel GRE is used to securely encapsulate the data or payload.

6. In the Remote network address field, enter the IP address scheme of the remote network.

7. In the Remote network subnetmask field, enter the subnet mask of the remote network.

8. The TTL (Time To Live) field is an 8-bit field used to remove an undeliverable data packet from a network to avoid unnecessary network traffic across the internet. The default value of 255 is the upper limit on the time that an IP datagram can exist. The value is reduced by at least one for each hop the data packet takes to the next router on the route to the datagram's destination. If the TTL field reaches zero before the datagram arrives at its destination the data packet is discarded and an error message is sent back to the sender.

9. The Verbose logging option sets the router to output detailed logs regarding the GRE tunnel in the System Log section of the router interface.

10. The Reconnect delay is the time in seconds that the router will wait before attempting to connect to the GRE server in the event that the connection is broken. The minimum time to wait is 30 seconds so as to not flood the GRE server with connection requests, while the maximum time to wait is 65335 seconds.

11. The Reconnect retries is the number of connection attempts that the router will make in the event that the GRE connection goes down. If set to 0, the router will retry the connection indefinitely, otherwise the maximum number of times to retry cannot be greater than 65335.

12. Click the Save button to save the changes. The VPN will attempt to connect after your click Save. Click the Status button at the top left of the interface to return to the status window and monitor the VPN's connection state.

Data stream manager

The data stream manager provides you with the ability to create mappings between two endpoints on the router. These endpoints may be physical or virtual, for example, a serial port connected to the router's USB port could be configured as an endpoint or you could configure a TCP Server as an endpoint. You can then configure a virtual data tunnel or "stream" between the endpoints.

The data stream manager provides a wide range of possibilities and expands upon simple PAD functionality to include the forwarding and translation of data between any of the endpoints. For example, you could send the GPS data from the built-in module to a TCP server running on the router. In each case, the logical flow of the stream is from Endpoint A to Endpoint B.

Customers interested in developing their own applications to create custom endpoints and streams can contact NetComm Wireless about our Software Development Kit.

Endpoints

The first thing to be done in order to create a data stream is to define the endpoints. There are 6 types of endpoint that may be configured:

Serial port (generic)
TCP Server
TCP Client
UDP Server
UDP Client
GPS Data (for devices with GPS receiver)

Figure 85 - Endpoints list

To create an endpoint:

1. Click the +Add button on the right side of the page. A pop-up window appears.

Figure 92 - GPS data endpoint configuration

1. Click the OK button. The router displays a screen with configuration options for your chosen endpoint type.
2. Enter the options for your endpoint as required.
3. Click the Save button. The Endpoints list is displayed with the newly created endpoint listed and a summary of the settings your configured.

Figure 93 - Endpoints list

Streams

When you have created the required endpoints, you can then proceed to set up a data stream. A data stream sends data from one endpoint to another, performing any transformation of the data as required. When a stream is added, an underlying process on the router checks the validity of the stream, checking for conflicts and illogical configurations.

Notes on data stream operation:

• When any changes to the Data stream manager configuration are detected, all data streams are stopped and restarted as per the new configuration.
  • Multiple Modbus clients cannot connect simultaneously to Modbus serial slaves connected to the router.

Every stream requires two endpoints, Endpoint A and Endpoint B. In all cases, the flow of data is from Endpoint A to Endpoint B. To create a new stream:

1. Click the +Add button on the right side of the page.

Figure 94 - Data stream list

The Edit data stream page is displayed.

1. In the Data stream name field, enter a name for the Data stream.

2. Under Endpoint A, use the Endpoint name drop down list to select one of the endpoints you created previously. This endpoint should be the starting point of the stream. Use the Mode drop down list to select the mode of operation of the endpoint. The mode can be thought of as a transformation of the data as it leaves this endpoint. For example, if Endpoint A type is Serial port (generic), the Mode can be set to various Modbus server and client types. This means that upon arrival at Endpoint A, the data will be transformed into the chosen Modbus format, ready to be sent to Endpoint B.

3. Under Endpoint B, use the Endpoint name drop down list to select one of the endpoints you created previously. This endpoint should be the destination of the stream. The screenshot below shows a configuration sending data received on an attached serial port to a TCP server running on the router. Use the Mode drop down list to select the mode of operation of the endpoint. The mode can be thought of as a transformation of the data as it arrives at this endpoint.

Figure 95 · Edit data stream

1. Click the Save button. The new stream appears in the Data stream list.

Figure 96 - Data stream list

PADD

PAD Daemon is a tool used to encapsulate raw serial data into a TCP packet to be transported over IP to another end point. The server receiving the TCP packets unpacks the data and the original raw serial data is passed out of its serial port to the attached device, thereby creating an invisible IP network to the two serial devices.

The PAD Daemon runs as a background process which can be accessed via the web configuration interface. The PADD configuration page is located under "Services > PADD". The PADD is used usually with multiple connections or when redundant connections are needed. The PADD has two modes: the PADD TCP/IP Server mode and PADD TCP/IP Client Mode. When PADD is enabled, both the PADD server mode and PADD client mode can be run at the same time.

The PADD configuration page is shown below.

The TR-069 (Technical Report 069) protocol is a technical specification also known as CPE WAN Management Protocol (CWMP). It is a framework for remote management and auto-configuration of end-user devices such as customer-premises equipment (CPE) and Auto Configuration Servers (ACS). It is particularly efficient in applying configuration updates across networks to multiple CPEs.

TR-069 uses a bi-directional SOAP/HTTP-based protocol based on the application layer protocol and provides several benefits for the maintenance of a field of CPEs:

Simplifies the initial configuration of a device during installation
Enables easy restoration of service after a factory reset or replacement of a faulty device
Firmware and software version management
Diagnostics and monitoring

Note: You must have your own compatible ACS infrastructure to use TR-069. In order to access and configure the TR-069 settings you must be logged into the router as the root user.

Note: When a factory reset of the router is performed via TR-069, the TR-069 settings are preserved.

GPS

On models with a built-in GPS, you are able to use location-based services, monitor field deployed hardware or find your current location. The GPS Status window provides up to date information about the current location and the current GPS signal conditions (position dilution of precision (PDOP), horizontal dilution of precision (HDOP) and vertical dilution of precision (VDOP)) of the router.

NMEA support

The router supports the National Marine Electronics Association NMEA-0183 compatible (V2.3) standard of sending GPS data. The standard includes "sentences" used to identify the type of data being sent and therefore defines the way the data is interpreted. The supported GPS related sentences are listed below:

GPGGA – Global Positioning System Fix Data, Time, Position and fix related data for a GNSS receiver
GPRMC – Recommended minimum data for GPS
GPGSV – Detailed satellite data
GPGSA – Overall satellite data
GPVTG – Vector track and speed over the Ground

GPS configuration

To access the GPS configuration screen, select the Services item from the top menu bar then the GPS item on the left. Finally, select the GPS configuration menu item.

To use the GPS function, set the GPS operation toggle key to ON and click the Save button.

USSD

Network Messaging, also known as Unstructured Supplementary Service Data (USSD) is a protocol that can be used to communicate from your device to your service provider. Depending on which network you use for your mobile broadband service, this page can be used for a variety of network services such as balance checking, recharging a prepaid service, and many others.

Network messaging can be initiated using special codes specified by your carrier for these various services. Once a special code is sent to the network, the network responds with the requested information. The response often includes instructions for sending additional follow-on messages allowing further functionality (e.g entering credit card information for a credit recharge).

Please contact your network provider to learn which codes can be used on your network for features such as balance checking, recharge, etc

To begin using this feature, please enter the dial string (e.g #100#) into the box below and click "Start Session". If you don't know which dial string to use, please contact your carrier, and ask them which dial codes are suitable for network services.

SMS forwarding configuration

Incoming text messages can be redirected to another mobile device and/or a TCP/UDP message server.

Redirect to mobile

You can forward incoming text messages to a different destination number. This destination number can be another mobile phone or a router phone number.

For Example:

If someone sends a text message and Redirect to mobile is set to "[phone]", the text message is stored on the router and forwarded to "[phone]" at the same time.

To disable redirection to a mobile, clear the Redirect to mobile field and click the Save button.

Redirect to TCP / UDP server address

You can also forward incoming text messages to a TCP/UDP based destination. The TCP or UDP server can be any kind of public or private server if the server accepts incoming text-based messages.

The TCP/UDP address can be an IP address or domain name. The port number range is from 1 to 65535. Please refer to your TCP/UDP based SMS server configuration for which port to use.

For Example:

If someone sends a text message and TCP server address is set to "192.168.20.3" and TCP port is set to "2002", this text message is stored in the router and forwarded to "192.168.20.3" on port "2002" at the same time.

To disable redirection to a TCP or UDP address, clear the TCP server address and UDP server address fields and click the Save button.

New message

The New message page can be used to send SMS text messages to a single or multiple recipients.

A new SMS message can be sent to a maximum of 9 recipients at the same time. After sending the message, the result is displayed next to the destination number as "Success" or "Failure" if the message failed to send. By default, only one destination number field is displayed. Additional destination numbers may be added one at a time after entering a valid number for the current destination number field. To add a destination number, click the + button and to remove the last destination in the list, click the - button.

Figure 107 - SMS - New Message

Destination numbers should begin with the "+" symbol followed by the country calling code. To send a message to a destination number, enter the "+" symbol followed by the country calling code and then the destination number.

For example:

To send a message to the mobile destination number 0412345678 in Australia (country calling code 61), enter "[phone]".

After entering the required recipient numbers, type your SMS message in the New message field. As you type your message, a counter shows how many characters you have entered out of the total number available for your chosen encoding scheme. When you have finished typing your message and you are ready to send it, click the Send button.

Diagnostics

The Diagnostics page is used to configure the SMS diagnostics and command execution configuration. This allows you to change the configuration, perform functions remotely and check on the status of the router via SMS commands.

To access the Diagnostics page, click on the Services menu item then select the SMS menu on the left and finally select Diagnostics beneath it.

Figure 110 - SMS diagnostics and command execution configuration

SMS diagnostics and command execution configuration

The options on this page are described below.

Enable remote diagnostics and command execution

Enables or disables the remote diagnostics feature. If this setting is enabled all incoming text messages are parsed and tested for remote diagnostics commands.

If remote diagnostics commands are found, the router executes those commands. This feature is enabled by default. All remote diagnostic commands that are received are stored in the Inbox.

Note: It is possible to adjust settings and prevent your router from functioning correctly using remote diagnostics. If this occurs, you will need to perform a factory reset in order to restore normal operation.

We highly recommended that you use the white list and a password when utilising this feature to prevent unauthorised access. See the White list description for more information.

Only accept authenticated SMS messages

Enables or disables checking the sender's phone number against the allowed sender white list for incoming diagnostics and command execution SMS messages.

If authentication is enabled, the router will check if the sender's number exists in the white list. If it exists, the router then checks the password (if configured) in the incoming message against the password in the white list for the corresponding sending number. If they match, the diagnostic or command is executed.

If the number does not exist in the white list or the password does not match, the router does not execute the incoming diagnostic or command in the SMS message.

This is enabled by default and it is strongly advised that you leave this feature enabled to maintain security.

Send Set command acknowledgement replies

The NTC-140W Series router will automatically reply to certain types of commands received, such as get commands, or execute commands. However acknowledgement replies from the NTC-140W Series router are optional with set commands and the Wakeup command. This option Enables or disables sending an acknowledgment message after execution of a set command or SMS Wakeup command. If disabled, the router does not send any acknowledgement after execution of a set command or SMS Wakeup command. All acknowledgment replies are stored in the Outbox after they have been sent. This can be useful to determine if a command was received and executed by the router. This option is disabled by default.

Access advanced RDB variables

By default, this option is turned off and only allows access to the basic RDB variables listed later in this guide. If this option is enabled, you are able to access the full list of RDB variables via SMS.

Allow execution of advanced commands

By default, this option is turned off and only allows execution of the basic commands listed later in this guide. If this option is enabled, you are able to execute advanced commands such as those which are common to the Linux command line. For example: "execute ls /usr/bin/sms*" to list the contents of the /etc folder on the router.

Send acknowledgement replies to

This option allows you to specify where to send acknowledgment messages after the execution of a set, get, or exec command.

If a fixed number is selected, the acknowledgement message will be sent to the number defined in the Fixed number to send replies to field. If the sender's number is selected, the acknowledgement message will be sent to the number that the SMS diagnostic or command message originated from. The default setting is to use the sender's number.

Fixed number to send replies to

This field defines the destination number to which error messages are sent after the execution of a get, set, or exec command. This field is only displayed when Send Error SMS to is set to Fixed Number.

Send command error replies

Enables or disables the sending of an error message resulting from the execution of a get, set, or exec command. All error replies are stored in the Outbox after they have been sent.

Send error replies to

When Send Error SMS for Get/Set/Exec Command is set to ON, this option is used to specify where the error SMS is sent. Use the radio buttons to select either Fixed Number or SMS Sender Number. When set to SMS Sender Number the router will reply to the originating number of the SMS diagnostic or command. When set to Fixed Number the router will send the error messages to the number specified in the following field.

Send a maximum number of

You can set the maximum number of acknowledgement and error messages sent when an SMS diagnostic or command is executed. The maximum limit can be set per hour, day, week or month. The router will send a maximum of 100 replies by default.

The number of messages sent is shown below the options. The total transmitted message count resets after a reboot or at the beginning of the time frame specified.

White List for diagnostic or execution SMS

The white list is a list of mobile numbers that you can create which are considered "friendly" to the router. If Only accept authenticated SMS messages is enabled in the diagnostics section, the router will compare the mobile number of all incoming diagnostic and command messages against this white list to determine whether the diagnostic or command should be executed. You may optionally configure a password for each number to give an additional level of security. When a password is specified for a number, the SMS diagnostic or command message is parsed for the password and will only be executed if the number and password match.

Figure 111 - White list for diagnostic or execution SMS

A maximum of 20 numbers can be stored on the router in the white list. To add a number to the white list, click the "+Add" button.

Figure 112—Adding a number to the SMS white list

The White List numbers and passwords can be cleared by pressing the ✗ button to the right of each entry. To add a number to the white list, enter it in the Destination number field and optionally define a password in the Password field. When you have finished adding numbers click the Save button to save the entries.

Sending an SMS Diagnostic Command

Follow the steps below to configure the router to optionally accept SMS diagnostic commands only from authenticated senders and learn how to send SMS diagnostic commands to the router.

1. Navigate to the Services > SMS messaging > Diagnostics page
2. Confirm that the Enable remote diagnostics and command execution toggle key is set to the ON position. If it is set to OFF click the toggle key to switch it to the ON position.
3. If you wish to have the router only accept commands from authenticated senders, ensure that Only accept authenticated SMS messages is set to the ON position. In the White list for diagnostic or execution SMS messages section, click the +Add button and enter the sender's number in international format into the Destination number field that appears. If you wish to also configure a password, enter the password in the Password field corresponding to the destination number.
4. If you would prefer to accept SMS diagnostic commands from any sender, set the Only accept authenticated SMS messages toggle key to the OFF position.

Note: An alternative method of adding a number to the white list is to send an SMS message to the router, navigate to Services > SMS messaging > Inbox and then click the button next to the message which corresponds to the sender's number.

1. Click the Save button.

Types of SMS diagnostic commands

There are three types of commands that can be sent; execute, get and set. The basic syntax is as follows:

execute COMMAND
get VARIABLE
set VARIABLE=VALUE

If authentication is enabled, each command must be preceded by the password:

PASSWORD execute COMMAND
PASSWORD get VARIABLE
PASSWORD set VARIABLE=VALUE

The following are some examples of SMS diagnostic commands:

password6657 execute reboot
get rssi
set apn1=testAPNvalue

SMS acknowledgment replies

The router automatically replies to get commands with a value and execute commands with either a success or error response. Set commands will only be responded to if the Send Set command acknowledgement replies toggle key is set to ON. If the Send command error replies toggle key is set to ON, the router will send a reply if the command is correct but a variable or value is incorrect, for example, due to misspelling.

SMS command format

Generic Format for reading variables:

get VARIABLE

PASSWORD get VARIABLE

Generic Format for writing to variables:

set VARIABLE=VALUE

PASSWORD set VARIABLE=VALUE

Generic Format for executing a command:

Execute COMMAND

PASSWORD execute COMMAND

Replies

Upon receipt of a successfully formatted, authenticated (if required) command, the gateway will reply to the SMS in the following format:

TYPE	SMS CONTENTS	NOTES
get command	"VARIABLE=VALUE"
set command	"Successfully set VARIABLE to VALUE"	Only sent if the acknowledgment message function is enabled
execute command	"Successfully executed command COMMAND"

Table 30 - SMS Diagnostic Command Syntax

Where "VARIABLE" is the name of the value to be read

Where "VARIABLE (x)" is the name of another value to be read

Where "VALUE" is the content to be written to the "VARIABLE"

Where "COMMAND" is a supported command to be executed by the device (e.g. reboot)

Where "PASSWORD" is the password (if configured) for the corresponding sender number specified in the White List

Multiple commands can be sent in the same message, if separated by a semicolon.

For Example:

get VARIABLE1; get VARIABLE2; get VARIABLE3

PASSWORD get VARIABLE1; get VARIABLE2

set VARIABLE=VALUE1; set VARIABLE2=VALUE2

PASSWORD set VARIABLE1=VALUE1; set VARIABLE2=VALUE2; set VARIABLE3=VALUE3

If required, values can also be bound by an apostrophe, double apostrophe or back tick.

For Example:

“set VARIABLE='VALUE'"

“set VARIABLE="VALUE””

“set VARIABLE=VALUE”

"get VARIABLE"

A password (if required), only needs to be specified once per SMS, but can be prefixed to each command if desired.

"PASSWORD get Variable1"; "get VARIABLE2"

"PASSWORD set VARIABLE1=VALUE1"; "set VARIABLE2=VALUE2"

If the command sent includes the "reboot" command and has already passed the white list password check, the device keeps this password and executes the remaining command line after the reboot with this same password.

For Example:

"PASSWORD execute reboot; getVariable1"; "get VARIABLE2"

"PASSWORD execute reboot; PASSWORD get Variable1"; "get VARIABLE2"

Note: Commands, variables and values are case sensitive.

List of basic commands

A list of basic commands which can be used in conjunction with the execute command are listed below:

"pdpcycle", "pdpdown" and "pdpup" commands can have a profile number suffix 'x' added. Without the suffix specified, the command operates against the default profile configured on the profile list page of the Web-Ul.

#	COMMAND NAME	DESCRIPTION
1	reboot	Immediately performs a soft reboot.
2	pdpcycle	Disconnects (if connected) and reconnects the data connection. If a profile number is selected in the command, try to disconnect/reconnect the specified profile in case the profile is active. If no profile number is selected, try to disconnect/reconnect the current active profile. Reports an error if no profile number is selected and there is no currently activated profile.
3	pdpdown	Disconnects the PDP. If a profile number is selected in the command, the router tries to disconnect the specified profile in case the profile is active. If no profile number is selected, try to disconnect the current active profile. Reports an error if no profile number is selected and there is no currently activated profile.
4	pdpup	Reconnects the PDP. If a profile number is selected in the command, the router tries to connect with the specified profile. If no profile number is selected, the router tries to connect to the last active profile. The gateway will check the currently activated profile and disconnect this profile before executing the command. The router reports an error if no profile number is selected and there is no stored last active profile number.
5	factorydefaults	Performs a factory reset on the router. Be aware that this command also clears the SMS white list on the router.
6	download	Performs a download and install of a Firmware Upgrade (.cdi), Config File (.tar.gz) or a help document (.pdf) file.If the file is a firmware image as in the case of a .cdi file, the router will apply the recovery image first and then the main firmware image. The download location is specified immediately after the command and may be from an HTTP or FTP source URL.If the file is a .tar.gz file, the router will apply the file as a configuration file update for the device and reboot afterwards.If the file is a .pdf, the router will assume this is a user guide document and save it to the router and make the file available for viewing via the help menu on the Web-UI.Note: If your download URL includes any space characters, please encode these prior to transmission according to RFC1738, for example:ftp://username:password@serveraddress/directory%20with%20spaces/filename.cdiNote: Authenticated FTP addresses may be used following the format as defined in RFC1738, for example:ftp://username:password@serveraddress/directory/filename.cdi
7	codconnect	Causes the router to activate the PDP context when the Connect on demand feature is enabled.
8	coddisconnect	Causes the router to de-activate the PDP context when the Connect on demand feature is enabled.
9	wakeup	This forces the default Data connection profile to connect if it is in a disconnected or waiting state. There are two circumstances in which this command may be useful; where the default profile is enabled but has been manually disconnected and if Connect on demand is enabled and the router is awaiting packet of interest. In both of these situations, the wakeup command will cause the default PDP context to activate.
10	ssh.genkeys	Instructs the router to generate new public SSH keys.
11	ssh.clearkeys	Instructs the router to clear the client public SSH key files.

Network scan and manual network selection by SMS

Performing a network scan

The get plmnscan SMS command enables you to perform a scan of the cellular networks available at the time of the scan.

It returns the following semi-colon separated information for each network in range:

MCC
MNC
Network Type (LTE, 3G, 2G)
Provider's Name
Operator Status (available, forbidden, current)

The following is an example of a response from the get plmnscan SMS command:

plmnscan:505,3,7,vodafone AU,4;505,3,1,vodafone AU,1;505,2,7,YES OPTUS,1;505,2,1,YES OPTUS,1;505,1,1,Telstra Mobile,1;505,1,7,Telstra Mobile,1

NETWORK TYPE	DESCRIPTION
9	Indicates an LTE network.
7	Indicates a 3G network
1	Indicates a 2G network

Table 3-4 - Network types returned by get plmnscan SMS command

OPERATOR STATUS	DESCRIPTION
1	Indicates an available operator which may be selected.
2	Indicates a forbidden operator which may not be selected (applies only to generic SIM cards).
4	Indicates the currently selected operator.

Table 3.5 - Operator status codes returned by get plmnscan SMS command

Notes about the network connection status when using the get plmnscan command:

• If the connection status is Up and connection mode is Always on, the get plmnscan SMS will cause the connection to disconnect, perform the scan, send the result through SMS and then bring the connection back up again. If the connection status is Down, the router will perform the PLMN scan, send the result and keep the connection status down.
• If the connection status is Waiting and connection mode is Connect on demand, the get plmnscan SMS will change the connection status to Down, perform the scan, send the result through SMS and then restore the connection status to the Waiting state.
• If the connection status is Up and connection mode is Connect on demand, the get plmnscan SMS will cause the connection to disconnect, perform the scan, send the result through SMS, and then restore the connection status to the Waiting state unless there is a traffic which triggers a connection in which case the connection status will be set to Up.

Setting the router to connect to a network

The router can be instructed by SMS to connect to one of the networks returned by the get plmnscan command. The set forceplmn command forces the router to connect to a specified operator network (if available) while the get forceplmn command retrieves the currently configured network on the router.

Command format:

set forceplmn=0|MCC,MNC| MCC,MNC,Network Type

For example:

set forceplmn=0

Sets the selection of operator and network type to automatic mode.

set forceplmn=505,3

Sets the operator to a manual selection made by the user where "505" is the Mobile Country Code for Australia and "3" is the Mobile Network Code for Vodafone. As no network type (e.g. LTE/3G/2G) is specified, it is selected automatically.

set forceplmn=505,3,7

Sets the operator and network type to a manual selection made by the user where "505" is the Mobile Country Code for Australia, "3" is the Mobile Network Code for Vodafone and "7" is the 3G network type.

Notes about the set forceplmn command:

1. If the manual selection fails, the device will fall back to the previous 'good' network.

2. When enabled, the SMS acknowledgement reply reflects the success or failure of the manual selection with respect to the set command and includes the final MNC/MCC that was configured.

Confirming the currently configured operator and network type

You can retrieve the currently configured operator and network type using the get forceplmn command.

The get forceplmn command returns the operator and network type selection mode (Automatic/Manual), in addition to the MCC and MNC values, for example:

Automatic,505,3

This response indicates that the operator/network selection mode is Automatic, and the network used is Vodafone AU.

System

Log

The Log pages are used to display or download the System log and IPSec logs on the router.

System log

The System Log enables you to troubleshoot any issues you may be experiencing with your NTC-140W Series router. To access the System Log page, click on the System menu. The System Log is displayed.

Figure 113 - System log file

Log file

Use the Display level drop-down list to select a message level to be displayed. The message levels are described in the table below.

To download the System log for offline viewing, right-click the Download button and choose Save as.. to save the file. To clear the System log, click the Clear button. The downloaded log file is in Linux text format with carriage return (CR) only at the end of a line, therefore in order to be displayed correctly with new lines shown, it is recommended to use a text file viewer which displays this format correctly (e.g. Notepad++).

Log data is stored in RAM and therefore, when the unit loses power or is rebooted, it will lose any log information stored in RAM. To ensure that log information is accessible between reboots of the router there are two options:

1. Enable the Log to non-volatile memory option
2. Use a remote syslog server

Enable the log to non-volatile memory option

When the router is configured to log to non-volatile memory, the log data is stored in flash memory, making it accessible after a reboot of the router. Up to 512kb of log data will be stored before it is overwritten by new log data. Flash memory has a finite number of program-erase operations that it may perform to the blocks of memory. While this number of program-erase operations is quite large, we recommend that you do not enable this option for anything other than debugging to avoid excessive wear on the memory.

Use a remote syslog server

The router can be configured to output log data to a remote syslog server. This is an application running on a remote computer which accepts and displays the log data. Most syslog servers can also save the log data to a file on the computer on which it is running allowing you to ensure that no log data is lost between reboots.

To configure the NTC-140W Series router to output log data to a remote syslog server:

1. Click on the System menu from the top menu bar. The System log item is displayed.
2. Under the Remote syslog server section, enter the IP address or hostname of the syslog server in the IP / Hostname [PORT] field. You can also specify the port number after the IP or hostname by entering a semi-colon and then the port number e.g. 192.168.1.102:514. If you do not specify a port number, the router will use the default UDP port 514.
3. Click the Save button to save the configuration.

IPSec log

The IPSec log section provides the ability for you to download the log for the IPSec VPN function. This can assist in troubleshooting any problems you may have with the IPSec VPN.

Figure 115 - IPSec log

Use the Log level drop down list to specify the type of detail you want to capture in the log and then click the Save button. When you change the logging level, any active IPSec VPN tunnels will be disconnected as a change in logging level requires the IPSec service to be restarted.

To download the IPSec log, click the Download IPSec log button and you will be prompted to save the file.

System configuration

Settings backup and restore

The settings backup and restore page is used to backup or restore the router's configuration or to reset it to factory defaults. In order to view the settings page you must be logged into the web user interface as root using the password admin. The backup / restore functions can be used to easily configure a large number of NTC-140W Series router by configuring one router with your desired settings, backing them up to a file and then restoring that file to multiple NTC-140W Series routers.

Figure 116 – Settings backup and restore

Back up your router's configuration

HTTPS key management

What is HTTP Secure?

HTTP Secure or HTTPS is the use of the HTTP protocol over an SSL/TLS protocol. It is used primarily to protect against eavesdropping of communication between a web browser and the web site to which it is connected. This is especially important when you wish to have a secure connection over a public network such as the internet. HTTPS connections are secured through the use of certificates issued by trusted certificate authorities such as VeriSign. When a web browser makes a connection attempt to a secured web site, a digital certificate is sent to the browser so that it can verify the authenticity of the site using a built-in list of trusted certificate authorities.

There are two main differences between how HTTPS and HTTP connections work:

1. HTTPS uses port 443 while HTTP uses port 80 by default.
2. Over an HTTPS connection, all data sent and received is encrypted with SSL while over an HTTP connection, all data is sent unencrypted.

The encryption is achieved through the use of a pair of public and private keys on both sides of the connection. In cryptography, a key refers to a numerical value used by an algorithm to alter information (encrypt it), making the information secure and visible only to those who have the corresponding key to recover (decrypt) the information. The public key is used to encrypt information and can be distributed freely. The private key is used to decrypt information and must be secret by its owner.

Each NTC-140W Series router contains a self-signed digital certificate which is identical on all NTC-140W Series routers. For a greater level of security, the router also supports generating your own unique key. Additionally, you may use third party software to generate your own self-signed digital certificate or purchase a signed certificate from a trusted certificate authority and then upload those certificates to the router.

Generating your own self-signed certificate

To generate your own self-signed certificate:

1. Click the System item from the top menu bar, then Administration from the side menu bar and then HTTPS key management.
2. Enter the certificate details using the appropriate fields. Each field must be completed in order to generate a certificate.

SSH key management

Secure Shell (SSH) is UNIX-based command interface and network protocol used to gain secure access to a remote computer, execute commands on a remote machine or to transfer files between machines. It was designed as a replacement for Telnet and other insecure remote shell protocols which send information, including passwords, as plain text.

SSH uses RSA public key cryptography for both connection and authentication. Two common ways of using SSH are:

Use automatically generated public-private key pairs to encrypt the network connection and then use password authentication to log on.
Use a manually generated public-private key pair to perform the authentication and allow users or programs to log in without using a password.

Figure 126 - SSH Server Configuration

SSH Server Configuration

To configure the SSH server settings:

1. Use the SSH Protocol drop down list to select the protocol that you want to use. Protocol 2 is more recent and is considered more secure.
2. Select the types of authentication you want to use by clicking the Enable password authentication and Enable key authentication toggle keys on or off. Note that you may have both authentication methods on but you may not turn them both off.
3. Click the Save button to confirm your settings.

Host key management

SSH keys provide a means of identification using public key cryptography and challenge response authentication. This means that a secure connection can be established without transmitting a password, thereby greatly reducing the threat of someone eavesdropping and guessing the correct credentials.

SSH Keys always come in pairs with one being a public key and the other a private key. The public key may be shared with any server to which you want to connect. When a connection request is made, the server uses the public key to encrypt a challenge (a coded message) to which the correct response must be given. Only the private key can decrypt this challenge and produce the correct response. For this reason, the private key should not be shared with those who you do not wish to give authorization.

The Host key management section displays the current public keys on the router and their date and timestamp. These public keys are provided in different formats, including DSA, RSA and ECDSA. Each format has advantages and disadvantages in terms of signature generation speed, validation speed and encryption/decryption speed. There are also compatibility concerns to consider with older clients when using ECDSA, for example.

Host key management

Key type	Date
ssh_host_key	2014-07-04 11:48:58
ssh_host_dsa_key	2014-07-04 11:49:15
ssh_host_rsa_key	2014-07-04 11:49:23
ssh_host_ecdsa_key	2014-07-04 11:49:23

Generating new keys

The complete set of keys can be re-generated by selecting the Generate keys button. This key generation process takes approximately 30 seconds to complete.

Downloading keys

The Get keys button allows you to download the complete set of public and private keys while the Get public keys button will download only the set of public keys.

Uploading your own key files

Click the Upload keys button to upload your own public key to the router.

Client key management

The Client Key Management section is used for uploading the public key file of clients. To upload a client public key, click the Upload button, browse to the file and click Open.

Client key management

Username	Hostname	Key type
		ClearUpload

When the file is uploaded, it is examined for validity. If the key file is not a valid public key, it will not be uploaded.

LED operation mode

The 8 front LED indicators may be turned off after a timeout period for aesthetic or power saving reasons. To access the LED Operation Mode page, click the System menu, then Administration on the left and finally select LED Operation Mode.

Figure 127 - LED Operation Mode

The Mode drop down list sets the operation mode of the LEDs on the front panel of the router. To set the lights to operate at all times, set this to Always on. To set the lights to turn off after a specified period, select Turn off after timeout. When configured to turn off after timeout, use the LED power off timer field to specify the time in minutes to wait before turning off the LED indicators. The LED Power Off Timer must be an integer between 1 and 65535.

The wait period begins from the time the Save button is clicked. When the wait period expires, the LEDs will turn off. If the router is rebooted, the LED power off timer is reset. The router will boot up and wait for the configured time before turning off again.

Watchdogs

To access the Watchdogs page, click the System menu item, then select the Watchdogs menu item on the left.

Figure 128 - Watchdogs Settings

Watchdogs are features which monitor the router for anomalies and restart the router if an anomaly occurs preventing its normal operation. When configured, the watchdogs feature transmits controlled ping packets to 1 or 2 user specified IP addresses to confirm an active connection. If the watchdog does not receive responses to the pings after a specified number of failures, it will reboot the device in a last resort attempt to restore connectivity.

We recommend using caution when implementing this feature in situations where the device is intentionally offline for a particular reason, for example, when Connect-on-demand has been enabled. This is because the watchdog expects to be able to access the internet at all times, and will always eventually reboot the router if access isn't restored by the time the various timers expire and the fail count is reached.

It is due to the nature of the watchdog being a last resort standalone backup mechanism that it will continue to do its job and reboot the device even when the Connect-on-demand session is idle, or the PDP context is disabled by the user. Therefore, we recommended that you disable this feature if Connect-on-demand is configured or if the PDP context is intentionally disconnected on occasion.

The watchdog works as follows:

a) The router sends 3 consecutive pings to the first destination address at the interval specified in the Periodic Ping timer field.
b) If all 3 pings to the first destination address fail, the router sends 3 consecutive pings to the second destination address at the Periodic Ping timer interval.
c) If all 3 pings to the second destination address fail, the router sends 3 pings to the first destination address using the Periodic Ping accelerated timer interval.
d) If all 3 accelerated pings to the first destination address fail, the router sends 3 pings to the second destination address at the Periodic Ping accelerated timer interval.
e) If all 3 accelerated pings to the second destination address fail, the router registers this as a fail and returns to step C.
When the number of failures reaches the number configured in the Fail count field, the router reboots. If any ping succeeds, the router returns to step A and does not reboot.

Note: The Periodic Ping timer should not be set to a value of less than 300 seconds to allow the router time to reconnect to the cellular network following a reboot.

To disable the periodic ping reset monitor, set Fail count to 0.

Figure 129 – Ping watchdog settings

Configuring Periodic Ping settings

The Periodic Ping settings configure the router to transmit controlled ping packets to 2 specified IP addresses. If the router does not receive responses to the pings, the router will reboot.

To configure the ping watchdog:

1. In the First destination address field, enter a website address or IP address to which the router should send the first round of ping requests.
2. In the Second destination address field, enter a website address or IP address to which the router should send the second round of ping requests.
3. In the Periodic Ping timer field, enter an integer between 300 and 65535 for the number of seconds the router should wait between ping attempts. Setting this to 0 disables the ping watchdog function.
4. In the Periodic Ping accelerated timer field, enter an integer between 60 and 65535 for the number of seconds the router should wait between accelerated ping attempts, i.e. pings to the second destination address. Setting this to 0 disables the ping watchdog function
5. In the Fail count field, enter an integer between 1 and 65535 for the number of times an accelerated ping should fail before the router reboots. Setting this to 0 disables the ping watchdog function.

Disabling the Periodic Ping reset function

To disable the Periodic Ping reset function, set Fail count to 0.

Note: The traffic generated by the periodic ping feature is usually counted as chargeable data usage. Please keep this in mind when selecting how often to ping.

Configuring a Periodic reboot

The router can be configured to automatically reboot after a period of time specified in minutes. While this is not necessary, it does ensure that in the case of remote installations, the router will reboot if some anomaly occurs.

1. In the Force reboot every field, enter the time in minutes between forced reboots. The default value is 0 which disables the Periodic reboot function. The minimum period between reboots is 5 minutes while the maximum value is 65535 minutes.
2. If you have configured a forced reboot time, you can use the Randomise reboot time drop down list to select a random reboot timer. Randomising the reboot time is useful for preventing a large number of devices from rebooting simultaneously and flooding the network with connection attempts. When configured, the router waits for the configured Force reboot every time and then reboots after waiting for a random period that is less than or equal to the Randomise reboot time setting.
3. Click the Save button to save the settings.

Note: The randomise reboot time is not persistent across reboots; each time the router is due to reboot, it randomly selects a time less than or equal to the Randomise reboot time.

Power management

The Power management page provides you with an overview of the power profiles and the ability to configure them. Up to five power profiles may be configured and all of them may be active simultaneously. The Status column indicates whether the profile is active, while the Sleep mode and Wake mode columns summarise the method used to sleep or wake the modem.

Note: When configuring multiple power profiles, be careful so that they do not overlap or conflict with one another, for example, configuring a schedule which wakes up the unit when another profile has it scheduled to be in low power mode.

Figure 130 · Power management

To edit a power profile, click the Edit icon of the appropriate profile.

Figure 131 - Power management - Power profile settings

Sleep settings

Use the Sleep mode drop down list to select a condition under which the router should enter the sleep state.

Sleep after timer

When this mode is selected, the router will enter the sleep state after the number of minutes specified in the Sleep after field, regardless of the state of the ignition pin.

Figure 132 - Sleep after timer

Sleep at scheduled time

When this mode is selected, the router goes to sleep at the time specified in the Schedule sleep at field, regardless of the state of the ignition pin. Enter the time in 24 hour format without the semi-colon.

Figure 133 - Sleep at scheduled time

Sleep triggered by ignition pin

This mode sets the router to enter sleep state when the signal on the ignition pin reaches the specified value.

Figure 134 - Sleep triggered by ignition pin

Use the Sleep when ignition pin goes setting to select Low or High. By default, this is set to Low. Additionally, the router will stay on for the number of minutes specified in the Remain awake after ignition off field. The minimum value for this field is 2 minutes with the maximum being 255 minutes.

Wake settings

Use the Wake mode drop down list to select a condition under which the router should return from the sleep state.

Wake triggered by ignition pin

This mode sets the router to wake up when the signal on the ignition pin reaches the specified value.

Figure 135 - Wake up triggered by ignition pin

Use the Wake up when ignition pin goes setting to select Low or High. By default, this is set to High.

Wake up at scheduled time

When this mode is selected, the router wakes up at the time specified in the Schedule wake up at field, regardless of the state of the ignition pin. Enter the time in 24 hour format without the semi-colon.

Figure 136 - Wake up at scheduled time

Enter the time in seconds to wait before returning from sleep state in the Always wake up after field. A setting of 0 means that the router will automatically wake from sleep state immediately.

USB-OTG

The USB-OTG page displays the current status of the USB port, i.e. whether it is in Device mode or Host mode. By default, Automatic mode is set to ON, allowing the router to intelligently choose the correct mode. If you wish to manually override this selection, you can turn off Automatic mode and set Host or Device mode yourself.

Figure 137 - USB-OTG configuration

Storage

The Storage page provides configuration options with relation to USB and SD storage devices.

Storage device list

The Storage devices list displays any connected storage devices and summarises the type, file system, size, used and available space on each device. Additionally, an eject button is provided to unmount the storage device so you can safely remove it.

Restoring factory default settings

Restoring factory defaults will reset the NTC-140W Series router to its factory default configuration. You may encounter a situation where you need to restore the factory defaults on your NTC-140W Series router such as:

You have lost your username and password and are unable to login to the web configuration page;
You are asked to perform a factory reset by support staff.

There are two methods you can use to restore factory default settings on your NTC-140W Series router:

Using the web-based user interface
Using the reset button on the interface panel of the router

Using the web-based user interface

To restore your router to its factory default settings, please follow these steps:

1. Open a browser window and navigate to the IP address of the router (default address is http://192.168.1.1). Login to the router using root as the User Name and admin as the password.
2. Click the System item from the top menu bar, then System configuration on the left menu and then click Settings backup and restore.
3. Under the Restore factory defaults section, click the Restore defaults button. The router asks you to confirm that you wish to restore factory defaults. Click OK to continue. The router sets all settings to default. Click OK again to reboot the router.
4. When the Power light returns to a steady red, the reset is complete. The default settings are now restored.

Using the reset button on the interface panel of the router

Use a pen to depress the Reset button on the device for 15-20 seconds. The router will restore the factory default settings and reboot.

When you have reset your NTC-140W Series router to its default settings you will be able to access the device's configuration web interface using http://192.168.1.1 with username admin or root and password admin.

Appendix C: Recovery mode

The NTC-140W Series Router features two independent operating systems, each with its own file systems. These two systems are referred to as 'Main' and 'Recovery'. It is always possible to use one in order to restore the other in the event that one system becomes damaged or corrupted (such as during a firmware upgrade failure). The recovery console provides limited functionality and is typically used to restore the main firmware image in the case of a problem.

Accessing recovery mode

Both systems have web interfaces that can be used to manipulate the other inactive system. The NTC-140W Series Router starts up by default in the Main system mode, however the router may be triggered to start in recovery mode if desired.

To start the router in recovery mode:

1. Press and hold the physical reset button on the interface panel of the router for 5 to 15 seconds. When the LEDs on the front panel change to amber and countdown in a sequence, release the reset button. The router then boots into recovery mode.
2. In your browser, navigate to http://192.168.1.1. The router's recovery mode is hardcoded to use this address regardless of the IP address that was configured in the main system. The router's recovery console is displayed.

Appendix G: Input/Output

Overview

The NTC-140W series router is equipped with a 2 x 2 Molex connector providing a multipurpose input and output terminal as well as a dedicated ignition input. The I/O terminal may be independently configured for various functions, including:

NAMUR (EN 60947-5-6 / IEC 60947-5-6) compatible sensor input
Proximity sensor input for use with contact closure (open/closed) type of sensors (PIR sensors, door/window sensors for security applications) with the input tamper detection possible (four states detected: open, closed, short and break) by the use of external resistors
Analogue 0V to 30V input
Digital input (the I/O voltage measured by the Analogue input and the software making a decision about the input state) with the threshold levels configurable in software
Open collector output.

Hardware Interface

The interface of the input/output terminals are based on the circuit diagram below

The Input/Output label is the physical connection to the outside world. There are protection devices and resistor dividers to condition the signal prior to it going into the processor. The three labels to the right are the interface to the processor. Output Enable activates the Transistor which provides an open collector (ground) output and can sink 200mA at 23C. It is protected by a resettable fuse and transient protection diode. If used with the pull up resistor, which can be activated by the Pull up Voltage Enable pin, then you can have a High or Low output rather than open drain. The resistor can be pulled up to 3V3 for Cmos compatible output or 8.2V by software. The Analogue Input pin can read values from 0V to 30V. It is divided by a resistor network to read appropriate levels in the processor. Depending on the sensor type used, the pull up resistor can be switched on or off. If using the NAMUR sensor configuration the pull up will be activated to 8V2 by default.

Wiring Examples

The following examples are shown as a guide as to what can be achieved by the I/O features. It is up to the system integrator to have enough knowledge about the interface to be able to achieve the required results.

Note: NetComm Wireless does not offer any further advice on the external wiring requirements or wiring to particular sensors, and will not be responsible for any damage to the unit or any other device used in conjunction with it. Using outputs to control high voltage equipment can be dangerous. The integrator must be a qualified electrician if dealing with mains voltages controlled by this unit.

Open Collector Output driving a relay

Any output can be configured to control a relay. This is an example where the transistor will supply the ground terminal of the solenoid. External voltage is supplied to the other side of the solenoid.

Relay wiring depends on the requirement of the device being controlled.

Logic level Output

An output can be used with the pull up resistor to provide a logic level output which would be suitable to control an external digital device.

    B --> C["1K"]
    C --> D["Output"]
    E["External device being controlled."] --> F["Digital Input"]

LED Output

An LED can be controlled by simply providing an open collector ground to an externally powered LED Resistor value and Voltage will need to suit the LED type used. Alternatively an LED can be powered using 8V2 via 1K resistor. The suitability of the LED will need to be investigated.

Digital inputs

There are several ways to connect a digital input. A digital input can be anything from a simple switch to a digital waveform or pulses. The unit will read the voltage in as an analogue input and the software will decode it in a certain way depending on your configuration.

Below is a contact closure type input, which is detecting an Earth. Pull up is activated for this to work.

The following input detects an input going high. The turn on/off threshold can be set in the software.

graph LR

    B --> C["Input"]

NAMUR Sensor

A NAMUR sensor is a range of sensors which conform to the EN 60947-5-6 / IEC 60947-5-6 standards. They basically have two states which are reflected by the amount of current running through a sense resistor.

Analogue Sensor with Voltage output

There are various analogue sensors that connect directly to the unit which can provide a voltage output. These would require an external power source which may or may not be the same as the unit itself. The voltage range they provide can be between 0V and 30V. Some common sensor output ranges include 0V to 10V. The pull up resistor is not activated in this case.

Analogue Sensor with 4 to 20mA output

Another common type of sensor type is the 4-20mA current loop sensor. It provides a known current through a fixed resistor, usually 250 ohms thus producing a voltage of 0V to 5V at the input. The sensor would require an external power source which may or may not be the same as the unit itself. It will also require an external resistor. The internal pull up resistor is not activated.

Analogue Sensor with Thermistor

Some sensors work by changing resistance due to a change, such as temperature, light etc. These may be wired up to an external or internal power source and the resistance can be read into the analogue signal. This will require some software calibration like scaling or offset to map the voltage received to the sensor resistor value. An example below shows the internal pull-up voltage and 1K resistor activated. The voltage received depends on the combination of resistors and the value of the resistance of the sensor itself.

System Example – Solar powered Router with battery backup

The previous examples of wiring can be used to come up with a system. The following test case is an example of how the I/O's can be used to enhance a simple router setup.
