3. Getting Started

Unpacking the Arctic

Arctic is delivered in a bulk package containing only the device itself. Arctic EDGE Router does not
have manufacturing options.

A separate Arctic Accessory Kit (ordered separately) contains the following items:

• Power supply and cable

• Cross-over Ethernet Cable

• Null modem cable.

If any of the items are missing or are damaged, please contact Viola Systems Ltd. All packaging
materials are recyclable. Viola Systems urges its customers to follow environmental regulations
regarding the disposal of all materials.

Installation of the Arctic

The Arctic can be installed horizontally on a flat surface e.g. on a desk or a rack.

When installing Arctic models with wireless connectivity options it should be remembered that high­frequency radio waves need to be taken into account. The surrounding environment affects the range
of radio signals. Therefore, if you are using an Arctic with antennas directly mounted to the antenna
connector, try to avoid placing the Arctic where the radio signal might be disturbed (“shadowed”) by
nearby obstacles. Also large metallic surfaces (racks) may have a highly detrimental effect on the
antenna performance. In case of metal racks or surfaces it is recommended to use an external
antenna with an appropriately selected cable. By following these precautions the Arctic may be
installed more freely.

The stainless steel case of the Arctic contains option for DIN-rail mounting.

User’s Manual

Arctic EDGE Router 15 Viola Systems Ltd.

Setting of the IP Address Using a Console

Before installation you need to find out the required network settings. These include the IP Address,
Netmask and Gateway Settings used by the Arctic. The local network administrator can provide

them to you or you can ask for them from your Internet Service Provider.

1. Before beginning, turn off the power from all devices and check that the power switch of the
Arctic is in the “OFF” position.

2. Connect a serial cable (crossover) to the console serial port (RS1) and an Ethernet cable to
the RJ45 connector.

3. Switch the Arctic on by toggling the power switch to “ON” position

4. Connect to Arctic using COM port and terminal program (Hyperterminal). Serial settings for
console (RS1) are 19200-8-N-1 and none handshaking”.

5. Stop the PPCboot to get the “Arctic>” command prompt. Set the IP address and netmask
using command “setenv”

If possible, it is recommended to use an HTML browser to set up network settings as

described in the next chapter. If using a console, please follow the procedure below:

User’s Manual

Arctic EDGE Router 16 Viola Systems Ltd.

6. Save the setting with command “saveenv”.

7. Reboot the Arctic for the settings to take effect

.

(keepalive messages).

User’s Manual

Arctic EDGE Router 25 Viola Systems Ltd.

Monitor

Monitor is used for GPRS and VPN connection checking. If connection to the selected IP
address is lost, the connection is restarted. Monitor uses ICMP echo (ping) packets to check
the connection. When used with VPN, the remote IP peer address should be used. When it is
used, the monitor checks also the VPN connection.

ICMP Echo sending – Selects if the monitor is enabled.

Interval (sec) – Determines how often the connection is checked by sending ICMP echo

packets. The interval must be smaller than GPRS idle timeout (typically 2/3 of GPRS idle
timeout) in order to have uninterrupted communication

Reply timeout (secs) – The waiting time for reply packets.

Retries timeout (secs) – The number of tries before connections are restarted.

Target IP address – The host IP address to which echo packets are sent to. When VPN is

used, the Viola M2M Routers end peer address must be used to check the GPRS connection.

Secondary target IP address – The secondary host IP address to which ICMP echo packets
are to be sent if the sending to primary target host IP address fails.

Monitor should be always be enabled to make sure that the GPRS connection stays alive.

User’s Manual

Arctic EDGE Router 26 Viola Systems Ltd.

Routing

These parameters are used to configure routing settings:

Act as router – Enables IP forwarding between interfaces. Enabled by default.

Use Proxy ARP – Enables proxy ARP. May be used with Viola M2M Router VPN. Disabled

by default.

S-NAT

These parameters are used to configure S-NAT (source network address translation) settings.
When enabled, private IP address used in local LAN is changed to GPRS interface IP
address. By default, this feature is enabled from all IP addresses (0/0) in eth0. This means,
that users connected to Arctic Ethernet can use and for example browse the web by using
Arctic as default router.

From IP – Only S-NAT connections from the defined IP address are accepted. If defined with
wildcard (0/0), all IP addresses are handled the same way (only S-NAT connections are
allowed).

User’s Manual

Arctic EDGE Router 27 Viola Systems Ltd.

D-NAT

These parameters are used to configure D-NAT (destination network address translation)
settings. When enabled, packets coming to defined GPRS interface port are forwarded to
local IP address.

Source IP – D-NAT only connections coming from IP. Wildcard 0/0 means all IP addresses
are D-NATted.

Protocol – Chooses which protocol is port forwarded. If “ANY” is chosen, other parametes
are disregarded.

Dest.port – Chooses which GPRS interface is port forwarded to local Ethernet.

Redirect to IP – Chooses where port forwarding is done to.

Redir. port – Chooses which port port forwarding goes to.

For example, it Arctic GPRS ports 8000 and 10000 are needed to forwarded to device at IP

172.16.4.99, the following rules would be applied. With this configuration, the devices at

172.16.4.99 web server (TCP port 80) could be accessed with browser to Arctics GPRS IP
address. For example, if the GPRS has IP address 10.99.99.99, browser would be connected
to: http://10.99.99.99:8000

to get access to web server running on port 80 at host

172.16.4.99.

If DNAT is needed to limited to some networks only, the Source IP can be defined in
IP/netmask bits format. For example, if DNAT should work only from network 192.168.1.0, the
Source IP would be defined to destination NAT rules as 192.168.1.0/24.

User’s Manual

Arctic EDGE Router 28 Viola Systems Ltd.

DNS Update

These parameters are used to configure dynamic DNS. Arctic can report it’s dynamic IP
address to a DNS server. Arctic supports RFC 2136 dynamic setup.

The server pointed by Authoritative names server (eg. company’s own DNS server, for
example ISC BIND) must be configured to accept incoming DNS update messages.

TSIG can be used for better security in DNS updates.

SSH server is available in Arctic for secure connections. Configuration file located at
/etc/sshd_config may be edited manually.

SSH Server – Enables or disables the SSH server.

Telnet Server

Telnet server may be used to make terminal connections to the Arctic device shell. A more
secure way of performing remote management is based on the SSH.

Telnet server- Enables or disables the telnet server.

DHCP Server

DHCP server listens to broadcast DHCP queries and assigns IP address for host from the
configured pool. If needed, Arctic can act as a DHCP server. This is suitable for small remote
networks that have for example few laptops connected to the Arctic via an Ethernet hub or a
switch.

If you disable the web access settings, web configurator stops functioning and you will have to enable

it via console if you should need to use it again later.

DHCP Server – Enables or disables the DHCP server.

DHCP server assigns IP address for DHCP clients between the low and high address range.
For example, 10 IP address is given to DHCP IP pool in image below

Optional parameters can be used to give more network configuration for DHCP client hosts.

DNS Proxy

With DNS proxy, computers connected to Arctic Ethernet interface can use Arctic as DNS
server. Arctic will forward DNS queries to correct DSN server and local computers DNS
setting are not needed to be changed.

Configuring the DHCP server in an erroneous way may cause your network to function badly or may

prevent functioning altogether. Consult your network administrator for necessary information
before setting up the service.

7. GPRS and EDGE

The Arctic EDGE Router provides a direct and reliable GPRS/EDGE connection and data
transmission to stationary or GSM 850/900/1800/1900 mobile networks around the world.

In this Chapter the specialities related to GPRS and EDGE operation are described.

Placing Arctic EDGE Router

When choosing the installation site of Arctic, please remember that it uses radio waves for data
transmission. The surrounding environment affects the behavior of radio signals. Therefore, if you are
using an Arctic with the antenna mounted directly to the antenna connector (without an extension
cable), try to avoid placing the unit in a location where the radio signal might be shadowed by nearby
obstacles. Note also that large metallic surfaces (racks) or walls with metallic structures (cabling,
concrete iron) may highly degrade the antenna performance. In case of metal racks or surfaces it is
recommended to use an external antenna with an appropriate cable. This allows placing of the Arctic
more freely.

GSM/GPRS/EDGE Antenna

The Arctic EDGE Router includes a FME connector (male type) for an external antenna. It is possible
to use any kind of external 50 Ω dual-band antenna intended for GSM900 (880–960 MHz) and
GSM1800 (also known PCN) (1710–1880 MHz) frequency bands. Connect the antenna directly to the
connector provided for the antenna on the back panel of the Arctic unit.

Typically, commercially available antennas are provided with a flexible 50 Ω cable having a length of
2–3 meters and having a female type FME-connector.

The Arctic EDGE Router is tested with antennas from Hirschmann Rheinmetall Elektronik GmbH.
Examples of tested external antennas include the following sticker-type and magnetic mount antennas
shown below:

MCA 18 90 STRIPE, sticker type patch
antenna (above), and
MCA 18 90 MH , magnetic mount antenna
(right). Both antennas have a FME (female)
connector and L=250 cm RG174 cable.

SIM Card and Card Holder

Standard 3 V SIM cards may be used with the Arctic EDGE Router. A SIM card holder is located on
the back panel near the GPRS antenna connector. If you have the PIN code query enabled, first
check that the Arctic Configurator has a correct PIN code entered in the GPRS submenu. To operate
with SIM card follow the procedure below:

1. Power off the Arctic.

2. The SIM card holder contains a tray with a yellow eject button. Push this button in order to
eject the tray from the holder.

3. Put the SIM card onto the tray.

4. Insert the tray carefully back to the holder and press the tray until it is locked.

The card should only be inserted or removed while the GSM module has been placed in shutdown

mode. The SIM card holder has a card detection circuit that will in theory allow hot insertion
and removal of the card. However, hot insertion and removal are not recommended, since the
SIM card content may be corrupted if the card is removed while the GSM module is writing
data to it.

Configuring Arctic GPRS Settings

This chapter describes how to get GPRS interface up. For this SIM card with GPRS enabled is
required from you operator. GPRS settings (APN, username and password) also required from the
mobile operator. Please note that Arctic device automatically switches between GPRS and EDGE
networks without user interaction.

1. If your SIM card has the PIN code querying set, make sure you configure the PIN code before
inserting the card in the card holder. If PIN querying is not set, you may proceed with the card
installation procedure.

2. Connect to the Arctic and log in to Configurator.

3. Navigate to Network page from main navigation bar and select the GPRS sub page.

4. Set the access point name (APN) appropriately according to your mobile operators settings
(eg. “INTERNET” or “operatorname.com”).

5. Set the GPRS network username and password appropriately if your GPRS service requires
authentication.

6. If GPRS is used as default route, enable it. For example, if you just wont to browse the
internet over GRPS,

7. Optionally, set the PIN code and PPP idle timeout.

• If your SIM card has the PIN code set, type the code into the PIN code field.

• PPP idle timeout defines the time in seconds how often the Arctic resets the GPRS

connection if the connection is idle.

8. ICMP Echo is used to monitor GPRS connection between Arctic and a remote host. If the
designated host cannot be reached the GPRS connection is reset. This feature can be
enabled from Network/Monitor menu. Please refer to previous chapter previous for more
detailed description. It is always recommended to enable the Monitor.

9. Finally click Apply and then Commit to store the settings.

.
Reboot the Arctic for the settings to take effect. Check GPRS status from Network/Summary Menu.

If “Running Routes” does not show default (default router/default route), it possible that network
connection does not work correctly. Usually, either GPRS or VPN is the default route.

If the PIN code querying is enabled on the SIM card and the PIN code is entered wrongly three (3)

times, the card locks up and will then require that an additional code is to be entered to open
the card from locked state. It is thus important to set the code with the

before plugging the SIM card in.
