Introduction to the Wireless Routers

Wireless Connectivity

To determine which wireless technology is best suited for your application, the following
guideline will give you some indication of the differences in these technologies.

GPRS

GPRS is a basic low speed GSM data service offered by most GSM operators. It has a
basic upload speed of 11kb/s and a download speed of around 44kb/s. Although GPRS is
very reliable and almost universally available where GSM exists, it has a major drawback of
relatively long latency times with an average latency of around 700 – 900mS. GPRS is ideal
for telemetry applications (meter reading, remote monitoring of devices etc.) or low speed
transaction based systems such as ATM’s but it is unsuitable for video links.

EDGE

EDGE is an enhancement to GPRS which is effectively four times the speed in both the
upload and download directions (i.e. 176Kb/s down and 44kb/s up). It is however not as widely
available as GPRS, but is capable of providing low to medium grade streaming video due to
the higher bandwidth and lower latency.

UMTS HSDPA

HSDPA is an advanced technology which provides very high speed wireless mobile data.
Current speeds are 7.2Mb/s in the download direction depending on the network’s capabilities.
Because of the above, HSDPA is ideal for almost all applications which need reliable, high
speed networking. Applications include remote signage high quality CCTV and provision of
internet access to areas with no access to wired services.

HSUPA

HSUPA is the latest release of high speed wireless network which offers significantly improved
uplink speeds as denoted by the ‘U’ in the name. Uplink intensive applications such as CCTV
will benefit considerably from this technology.

Wireless Routers

Mobile Router

The Mobile Router is capable of connecting to GSM/GPRS/EDGE networks. Typical applica­tions are where reliability is important, but high speed is not a priority such as ATM machines,
credit cards authorizations and telemetry.

Broadband Router

The Broadband Router is capable of connecting to UMTS HSDPA / HSUPA networks. Typical
applications include remote office connectivity and CCTV video streaming.

Introduction

Product Features

The Wireless Routers have one RS-232/422/485 Serial interfaces, a integrated EDGE or
HSDPA modem depending on model, dual SIM slots and a single 10/100 Base-T Ethernet
interface.

A Wireless Router is capable of connecting a number of Ethernet devices via GSM/GPRS/
EDGE networks on the Mobile Router, or UMTS/HSDPA networks on the Broadband Router.
With always–on and DUAL SIM card technology they provide easy to deploy access to central
servers and the Internet via GSM networks. The Wireless Routers are capable of maintaining a
permanent PPP connection or alternatively making a connection on demand (dial-on-demand)
to the distant network. It also allows you to dial into an Ethernet network to access devices on
that network or dial out of an Ethernet network to connect to a remote RAS server.

Some of the features supported by the Wireless Routers are:

IP Masquerading, which allows one or more computers in a network without assigned IP
addresses to communicate with the Internet.

Port Forwarding, (sometimes referred to as tunnelling) which is the act of forwarding a network
port from one network node to another, can also be enabled.

The Firewall feature on the Wireless Routers allow you to implement security by setting up
Access Control rules. The Firewall feature allows you to control your connection denying any
unwanted traffic or simply viewing what traffic is passing through the Wireless Routers.

Another feature on the Wireless Routers is a DHCP server to dynamically allocate IP
Addresses to hosts connected to the Ethernet network.

VPN functionality is standard on the Wireless Routers, providing reliable and secure communi­cation between the Router and your corporate network.

Introduction

Wireless Routers

Security

Securing your Wireless Router is done on various levels. Authentication is required for
configuring the Wireless Routers. The administrator username is ‘root’ with the default
password being ‘xxx’. It is recommended that you change this password to protect against
unwanted configuration changes on the Router.

NOTE: DO NOT lose your password. If both the Bootloader and System passwords

are lost, you will need to send your Wireless Router back to Multenet to be
reprogrammed. There is a cost associated with this recovery procedure. You are
able to recover from a lost System password by erasing the Dataflash using the
Bootloader login. The firmware will then need to be uploaded via serial.

Firmware Updates

Multenet continues to develop its products extensively, with new firmware releases available
regularly. New releases may contain new protocols, new features, bug fixes, performance
improvements, etc.

These firmware updates can be downloaded from the Multenet website:

http://www.multenet.com/support/downloads.html

Alternatively, contact your local distributor or email Technical Support.

Firmware can be uploaded to the Wireless Routers via EtherPAD Explorer V1.5.2 and above
(included on CD).

Getting Started

GETTING STARTED

This chapter provides information on connecting your Wireless Router to the network. The
Wireless Routers operate on the GSM network and it is important to take signal strenth and
quality into account when installing these devices.

Getting Started

11

Getting Started

Wireless Routers

Inserting SIM cards

The Wireless Routers support Dual-SIM so that a second service provider can be used as a
backup should your primary service provider become unavailable.

On the front of the Wireless Routers, there are two SIM slots in which the SIM cards are
inserted. SIM slot 1 should be used for your primary service provider, and SIM 2 for the
secondary or backup operator. To insert the SIM cards, insert the SIM into the drawer which is
ejected by depressing the release button next to the SIM drawer. Ensure that the trays are fully
inserted before starting up the router. For a single SIM configuration the SIM1 slot should be
used.

Note: Your Subscriber Identity Module (SIM) card
is not included and must be obtained from your local
Cellular Service Provider.

A data enabled SIM card is required for

operation of

the Multenet Wireless Routers.

Attaching the Antenna

Antennas are supplied with Multenet’s range of wireless routers.

Attach the antenna to the connector on the front of the Wireless Router and fasten by turning.

In some cases, a combination of factors can mean that a suitable signal can only be obtained
by the use of additional optional antennas.

These issues include:
a. If the unit is inside a metal enclosure such as a DIN rail cabinet
b. Proximity to interference generating equipment such as large machinery
c. Distance from the nearest cell site
d. Shielding by concrete reinforcement (e.g. within a large shopping mall)

In these cases, contact Multenet to obtain information on installing aditional antennas.

Getting Started

10/100 Base-T Ethernet Network Connection

Connect to your router via the Ethernet Network through a 10/100 Base-T switch/hub or
directly via straight or crossover Ethernet cable.

Serial Port Connection

The Router is a DTE (Data Terminal Equipment) device. You need to choose the serial
cable best suited to your serial device. A number of cable options are available:

• Crossed Serial Cable (most commonly used).

• Full Crossed Serial Cable.

• Null-Modem Crossed Serial Cable. Connect to another DTE (Data Terminal Equipment)
device, such as a PC.

• Straight Serial Cable. Connect to a DCE (Data Communications Equipment) device such
as a Modem.

Configuration of the Wireless Router

There are a number of methods to configure the Router:

• Web Browser Configuration

• Configuration File Upload

• Telnet or Serial configuration

• BootP/DHCP

These configuration methods will be explained in the next chapter.

Discovering Multenet Devices

Please ensure that your system firewall is disabled, launch EtherPAD Explorer and click on
‘Scan’ to discover any Multenet devices on your local subnet.
or
Select [Run EtherPAD Explorer now] from the Autorun Menu to launch the executable from
the CD, then click on scan to start discovery.

Note: EtherPAD Explorer executable is available on
the Multenet Product CD, along with the installation for
MS Windows PCs

Getting Started

13

Getting Started

Wireless Routers

Click [Scan] in EtherPAD Explorer to find Wireless Routers and other Multenet products on
the local Ethernet segment. A broadcast is sent out to which Multenet products respond to. A
new device will have no IP Address set, unless a DHCP server is setup and has issued the
Router an IP Address. Identify the MAC Address on the Router to verify that the unit is online.
Multenet devices on remote segments and networks will not be seen by EtherPAD Explorer as
routers will block the broadcast.

You will need to [Set IP Address] to configure the Router via TCP/IP. Make sure the IP
Address falls in your local subnet. Ask your Network Administrator should you have issues
getting these details.

The default Root password is ‘xxx’. If an IP Address has already been set, it may be that the
DHCP server has assigned the network parameters. The Router, by default, is set to obtain an
IP Address from a DHCP server.

Wireless Routers

14

Getting Started

You can [Test connection] to check if the Router is reachable via TCP/IP. If the test fails,
check your IP Address and Subnet Mask settings.

Check that the IP Address you enter is not used by another host on the network. Duplicate IP
Addresses may cause unwanted network disruptions. Check the Troubleshooting Guide for
more fault-finding tips.

Wireless Routers

PPP (Point-to-Point Tunnelling Protocol)

There are two methods available for setting up PPP on the Wireless Router.

PPP Express - Wizard based setup to help you set up the PPP connection.

(Recommended)

Manual - Manual configuration for setting up a PPP connection.

PPP EXPRESS

Launch the PPP Express Setup Wizard, by clicking on the ‘PPP Express’ link. This will launch
the wizard in a separate browser window as indicated below. The wizard will guide you through
setting up a connection. Depending on your environment, you will have the option of clicking
through and in most cases use the default assigned values. The following steps below show
how to set up a Always-On wireless connection.

1. Connection Type

You have the option for selecting either GPRS/EDGE, also used for HSDPA (Packet Switched),
or GSM (Circuit Switched) for connecting to the remote network.

2.Dial-out Properties

Wireless Routers

24

Configuration

Three options are available to choose from: ‘It should start automatically’ for dial-on demand,
‘Always stay connected’ for a connection that will be permanently connected or ‘I will start
it manually’ in the case you want to manually control your connection. Select ‘Always stay
connected’ and click ‘Next’

3.Networking

PPP IP Addresses
To automatically get PPP IP addresses from the remote server, leave this option checked.
(Recommended). The PPP IP addresses are the IP Addresses used by the Router and the
remote server to associate with the PPP connection. Usually the remote dial-in server will
provide the IP Addresses to use.

Default Route
To use this connection as the default route, leave this option checked. (Recommended)
Enabling the default route option means that all packets not intended for the LAN will be
forwarded over the PPP connection. If the PPP connection is to the Internet then you should
enable this option. Otherwise change the network address and netmask mask fields to
configure exactly which network is on the other side of the PPP connection.

NAT
To hide the internal addresses, leave this option checked. (Recommended)
This is also known as Masquerading. All packets going through the Router over the PPP
connection will seem as if they originated from the Router itself. Masquerading is also used for
added security between the LAN and the PPP connection.

Configuration

25

Configuration

Wireless Routers

4.DNS

To automatically get the DNS servers from the remote server, leave this option checked.
Domain name servers are used to translate domain names (e.g.. multenet.com) to IP
addresses. Either use the DNS servers supplied by the remote server (recommended) or
manually configure them.

5. Call Properties

The APN (Access Point Node) is the name of the server you will authenticate with via the
wireless connection. This option is only required for GPRS/EDGE/HSDPA connections. For
most mobile networks the APN of “internet” can be used to connect to the Internet. Based on
your selection in step one, default values will be loaded in the fields for the calling properties.
For GPRS/EDGE/HSDPA, no changes need to be made.

6. Idle Timeout

Wireless Routers

26

Configuration

This option will terminate the PPP connection after it has been idle for the configured number
of seconds (recommended). If it is an always-on connection, the connection will re-establish
itself automatically. Valid timeouts are between 1 and 86400 seconds inclusive.

7. Authentication

The username and password is for authenticating (PAP or CHAP) on the node server and
should have been provided by your cellular service provider.

10. Update Configuration

To complete the setup of your PPP connection, click on ‘Update Configuration’. Take note of
the colour change of the ‘Apply Changes’ option in your navigation menu. Your new settings
will only become active once you click ‘Apply Changes’ and then ‘Save and Reboot with new
Settings’

Wireless Routers

Network

Configure PPP networking.

Local PPP IP - Assign a local IP Address to serial interface if remote unit requests
this. Usually used when configured as an access server (RAS, dial-in).
Default is 0.0.0.0. This default setting indicates that the remote side
should assign this value.

Remote PPP IP - Assign a remote IP Address to serial interface if remote unit requests
this. Usually used when configured as an access server (RAS, dial-in).
Default is 0.0.0.0. This default setting indicates that the remote side
should assign this value.

Masquerade - On an outgoing packet, change the source IP Address to that of the
Router (SNAT - Source Network Address Translation). Any received
packets will have their destination IP Address changed back to the IP
Address of the host which originated the connection. This is
also used for sharing a single IP Address among a whole network
(usually a LAN connected to the Internet with only one IP Address).

Dial out Settings

Set up your dial-out settings for connecting to the GSM network.

Operator Selection- By default, the router automatically negotiates which network operator
to select based on information provided by your service
provider. To manually select your operator when more than one
operator is available, uncheck the Operator Selection checkbox.

VPN

A Virtual Private Network (or VPN) allows you join two private networks that are separated by the
Internet or other publicly accessible network. The two end points of this “network” are private net­works that are seamlessly connected across a public network creating a “Virtual Private Network”
between them.

To set up a VPN to a remote network, check the ‘Create VPN Tunnel’ checkbox.

Configuration

33

Configuration

Wireless Routers

VPN Type

The Wireless Routers supports two types of VPN Tunnelling:

PPTP Point-to-Point Tunnelling Protocol (PPTP) is a protocol that allows for
extending networks through private “tunnels” over the public Internet.
L2TP Layer Two Tunnelling Protocol (L2TP) is a protocol that allows for extending
networks through unsecured “tunnels” over the public internet.

VPN Server IP Enter the public IP Address of your remote VPN server.

Username Enter your VPN account’s username.

Password Enter your VPN account’s password.

MTU You may need to in some cases change the Maximum Transmission Unit
(MTU) size for the VPN connection. In most cases, this can be left at default.

Use Encryption In the case that you are setting up a PPTP connection, check this box to
enable encryption. The Wireless Router supports 40bit and 128bit
encryption. If you are connecting over L2TP, encryption is currently
not supported.

Note: VPN Routing

Once you have completed the configuration for your
VPN server, you will need to set up a route to the
network of the VPN server in the ‘Routing’ configu­ration page. If you wish to configure the Router to use
the VPN as a Default Route, you will also be able to
set this up on the Routing page.

Note:

When terminating a L2TP VPN on a Microsoft server,
IPSec will need to be disabled. Please read the
Microsoft Knowledge base article for instructions on
disabling IPSec.

Port Forwarding

Port Fowarding is used to implement Port Address Translation (PAT). An incoming connection
to the Wireless Router’s PPP IP Address and a specific port will be forwarded to an internal
host and port.

Port Forwarding is usually used in conjunction with Masquerading.

Note:

A range of ports can be specified using two dots “..”.

The example below shows that port 1 to 100 are redirected to port 1 to 100 on IP address

192.168.20.101, while port 8080 is redirected to IP address 192.168.20.100 port 80 (HTTP)

Configuration

DHCP

DHCP allows you to assign IP Addresses to hosts connecting to your LAN, which don’t have IP
Addresses and have a DHCP client enabled.

To set up the Wireless Router as a DHCP server, check the ‘Enable DHCP Server’ box. Once
enabled, you will have the option of configuring the range and the lease time. You will only be
able to specify a range within your current network. Valid lease time is between 5 and 1440
minutes (1 day) inclusively.

Firewalling

Firewalling allows you to restrict traffic entering or leaving your network. Rules are applied to
incoming and outgoing packets and the packet will be forwarded if is satisfies all the rules.

You can enter a maximum 25 Firewall rules on the Wireless Router.

In the example below, the first line states that TCP packets received on any PPP Interface with
a destination on the LAN on port 5000 will be allowed through.
The second line states that all other traffic is denied.
If the first line applies, the rest of the rules are skipped. If the rule is for logging, the following
rules in the list will be evaluated.

The default rule is to accept all packets through the Router, allowing all packets unrestricted
access through the Router. Should a VPN be configured, any firewall rules attaining to the PPP
interface will apply also to the VPN interface.

Configuration

37

Configuration

Wireless Routers

Rules can match packets based on any combination of:

- Source interface

- Source IP (and Network mask)

- Source port

- Destination interface

- Destination IP (and Network mask)

- Destination port

- Protocol

For each rule you have the option of any one of the following actions.

(i) Drop Packets matching this rule are discarded and will not continue through the

Router.

(ii) Deny If the rule matches the packet, discard the packet and send an ICMP error

(iii) Accept Packets matching Accept rules are accepted and are passed through the

router.

(iv) Log Record this packet in the Firewall Log. The next rule is evaluated.

Firewall Rule Order

The order in which rules are compared against the packets entering the firewall are rule 1 first,
then rule 2, then rule 3, and so forth (up to a maximum of 25 rules). If a packet does not match
any rule in the list, the packet will be accepted and allowed through. The packet will also be
allowed through if it matches an ‘Accept’ rule.

New rules that are configured are added to the end of the list. It will be checked last in the rule
order.

Use the “move” link to change the position of the rule. Enter the new position you would like
the rule to be placed at.

Troubleshooting

TROUBLESHOOTING

This chapter briefly explains some troubleshooting methods to help diagnose problems
connecting to your Wireless Router.

Verifying MAC Addresses

When the Router leaves the factory, the only address associated with it will be its universally
unique Ethernet address. This is also referred to as the MAC (Media Access Control) address.
The MAC address is programmed at the factory and cannot be modified. It is a 12-digit
hexadecimal number and is printed on a bar-coded label on the side of the unit. Wireless
Router MAC addresses currently begin with ‘0020B7’. In the unlikely event of the Router not
having a MAC address programmed, the unit must be returned to Multenet for re-configuration.

Troubleshooting

63

Troubleshooting

Wireless Routers

Ping

Ping the Router to quickly verify that the device is reachable. Type the following from the
Command Prompt.

A Reply reveals that the Router is reachable.

If you observe a Timeout, there may be numerous reasons to this error. It could be a network
disruption or a Router failure (e.g.. Power Outage). Take note of ‘time’. If latency is high,
timeouts may occur during remote configuration or even ‘expected’ data throughput during
normal operation.

For example: Your office network is flooded with data transactions during daylight hours
(or your ISP peering links are congested at certain Peak hours). This results in links being
very latent (slow). Protocol standards dictate timeout parameters which cause packets to be
dropped if data acknowledgement doesn’t happen in a set time.

ARP

Use the ARP command to check that the IP Address you set the Router to belongs to the
Router. You may have configured the Router to the same IP Address as another device on the
network. Ping the Router’s IP Address as shown above.

From the Command Prompt, use the ARP command.

Contact your Network Administrator to investigate should there be any issues with duplicate IP
Address assignments.

Traceroute

Perform a Traceroute towards your Router to obtain a snapshot of network routing. This is
applicable to your PC being more than one hop away from the Router (i.e. not on the local
segment or subnet).

Wireless Routers

64

Troubleshooting

There may be a number of reasons why you may find the Traceroute failing at certain points
( from the ISP blocking ICMP packets, to incorrect routing, to physical line disruptions). An
email to the ISP of the network which contains the problem or even an email to your Network
Administrator will get some answers.

If the Traceroute results indicate the subnet in which your Router is in (or its Gateway IP),
then it is possible that your Router is powered off/malfunctioned or there is a cable/switch/hub
problem.

NOTE: MS Windows uses ‘tracert’. Other OS’ usually use ‘traceroute’.

Telnet

Use the Telnet command to connect to the TCP port of your PocketPAD. You will observe data
received from the connected serial device. You can send data to the serial device as well.

If you are unable to connect to the configured port, check your Router settings. If you have
made changes, you need to reboot the Router for it to take effect.

Check the Network Application settings. If ‘Remote Host/IP Address’ (and/or ‘Remote Port’)
is configured, you will need to connect from that specific host (:port). If the ‘Application Type’
is active, you won’t be able to telnet to the port (set it to Passive to test). Try ‘telnetting’ to the
Remote Host’s port to check if it opens a socket.

Error connecting to TCP port

How many hosts are connecting to each Network Application?
A maximum of 5 TCP and/or UDP network applications can be configured on the Router. Each
application can handle 5 socket connections (Total of 25 concurrent socket connections at any
one time with all applications configured as Passive).

Web Browser Proxy Settings

Check your Browser Proxy settings should you be able to successfully Ping the Router, but are
unable to connect to the Router’s Web Configuration.

If the Proxy is enabled, traffic is directed outside the LAN to the internet via a gateway. If you
cannot alter these Proxy settings, try using Telnet Configuration to alter the Router parameters.

Troubleshooting

Recovering from a Lost Password

Should you lose your Root password (default is ‘xxx’), you can recover from the fault by
erasing the Dataflash. You will need to know the Bootloader password (default is ‘user’).

If both passwords are lost, you can send the unit back to Multenet for recovery (there is a cost
associated with this recovery procedure).

Log into the Bootloader

Power recycle the Router. The LEDs will flash for a set time as configured by the Bootdelay
variable (default is 20 seconds).

Connect a terminal session (e.g. Hyperterminal) to COM 1 of the Router. Serial parameters
are 19200 baud rate, 8 data bits, 1 stop bit, no parity, no flow control.

While the LEDs are flashing, type the Bootloader password into the terminal session (default
is ‘user’). Simply recycle power again if the LEDs have stopped flashing and no Menu has
appeared after typing in the password.

Type ‘2’ (Upgrade Menu).

Type ‘5’ (Erase Dataflash). ‘y’ to confirm deletion.
The process will take a few minutes to complete and return to the Upgrade Menu.

Type ‘1’ (Change Upgrade Serial Speed) to match your serial line baud rate. The highest baud
rate of (230400) is recommended for a faster upload of data.

Change your terminal session speed to the configured Upgrade Serial Speed setting.
‘Enter’ to continue once you have reconnected.

Transfer the Router firmware via ‘Kermit’. You can find the latest firmware on the Multenet
website. Current or older firmware can be found on the CD shipped with the Router.

After the file upload, you will be prompted to set the baud rate back to 19200. The data will be
checked and verified.

Check if Autodetect is selected in the Router configuration.

Link/Activity (LNK/ACT) - This LED flashes as data is transmitted/received over the

Ethernet interface (if your configured serial device sends/
receives data). It will also light up if any packets are sent to the
interface, but are not destined for the serial device. If this LED
is OFF, check the Ethernet cable and the switch/hub or PC that
it is connected to. Remember: PC -> Crossed Ethernet cable;
Switch/Hub -> Straight Ethernet cable.

Cables

Crossed Serial Cable

In order for a computer (or other device) to communicate with the Router’s RS232 serial port,
a simple 3-wire crossed cable is usually sufficient. (If hardware-based handshaking is required
then see Full Crossed Serial Cable.) The three wires should be connected as follows, using
either a 9-pin or 25-pin connector for the computer’s serial port.

Full Crossed Serial Cable

In order to connect the Router’s RS232 serial port to another DTE class device (such as a
computer) a simple Crossed Serial Cable is often sufficient. However, some applications may
require the use of hardware-based flow control. Handshaking allows for higher data rates. In
this case, a seven-wire cable should be connected as follows, using either a 9-pin or a 25-pin
connector for the computer’s serial port.

Null-Modem Crossed Serial Cable

When attempting to use a simple Crossed Serial Cable to connect a DTE class device (such
as a computer) to the Router’s RS232 serial port, some devices will not transmit any data
unless their DSR and CTS signals are asserted. An easy way to fix this is to simply drive
these signals using the device’s own DTR signal. In this the three wires should be connected
as follows, using either a 9-pin or 25-pin connector for the computer’s serial port, and the
indicated loops should be added.

Straight Serial Cable

In order to connect the Router’s RS232 serial port to a DCE class device (such as a modem)
a straight serial cable should normally be used. In this case, a nine-wire cable should be
connected as follows, using either a 9-pin or a 25-pin male connector for the DCE class
device.
