1. Plug the AirLink Helix power adapter into the power connector on the back
panel of the AirLink Helix. Wait approximately two minutes to allow the AirLink
Helix and modem to initialize.
2. Connect your computer to the AirLink Helix with an ethernet cable. Users can
also connect with Wi-Fi using “helix” as the default network name.
3. If the modem is not automatically detected, and if you are a first time user,
you may need to configure your cellular modem through the WAN page in the
ACEmanager with your web browser at 192.168.2.1. The username is admin
and default password is 12345. For more details on configuring the AirLink
Helix, refer to the chapter titled “Using the ACEmanager.”

2: Connecting a Computer to the AirLink
Helix
2
Any laptop, desktop, handheld, printer, or other computing device that
supports Ethernet (or optional Wi-Fi) can connect to the AirLink Helix.
If your computer supports these common network interfaces, you
don’t need to install any additional software to connect to the AirLink
Helix.
Before connecting multiple devices to the AirLink Helix for the first
time, it is a good idea to connect one computer first and verify that
the Product Name is successfully connected to the Internet. You may
need to use AirLink Helix ACEmanager to verify that the Helix device
is properly configured. See the “Configuring AirLink Helix” chapter for
more information.

Connecting Through Ethernet
To connect to the AirLink Helix using Ethernet, simply plug one end of
an Ethernet cable into your computer, and plug the other end into
either of the Ethernet ports on the AirLink Helix.
There are two Ethernet ports on the Helix. In most configurations,
both can be used for LAN connections. In WAN failover mode, one is
used for a WAN port to connect to another Internet service like a DSL
or cable modem.
Make sure your computer is setup for DHCP addressing. To setup the
AirLink Helix for static IP addressing, refer to the LAN Page section in
“Using the ACEmanager”.

AirLink Helix User Guide
Connecting Through Wi-Fi
Wi-Fi is available as an option on some versions of the Helix RT.
To connect wirelessly to the AirLink Helix using a Wi-Fi equipped computer,
simply select the network name “helix” using the Wi-Fi connection software
provided with your operating system or Wi-Fi network interface.
You can customize the network name and other Wi-Fi configuration options using
the LAN/Wi-Fi page in the ACEmanager. For more information, see the “Using the
ACEmanager” chapter.
Note: If you don’t change the default security settings in the ACEmanager for the AirLink
Helix, the AirLink Helix is accessible to any Wi-Fi device. For information about Wi-Fi
security, see the Security Page section in the “Using ACEmanager” chapter.
The AirLink Helix Wi-Fi network is based on the 802.11b/g. By default you can
also use computers equipped with 802.11b Wi-Fi hardware because 802.11g is
backwards compatible with 802.11b.
If you have trouble connecting automatically to the AirLink Helix using Wi-Fi, try
the following:
•
Make sure the “helix” network name is selected in the list of available
networks with your computer’s Wi-Fi connection software.
•
•
•
Turn your computer’s Wi-Fi connection off and then on again.
Restart your computer.
Check to see that your computer’s network configuration is consistent with the
configuration of the AirLink Helix. The default AirLink Helix configuration
requires your computer to use a DHCP connection.
•
For Windows XP users, check to see that you have Service Pack 2 or higher
installed. To determine if you have Service Pack 2 installed, open the Control
Panel and then open the System application.
•
•
Change the Wi-Fi channel in the AirLink Helix ACEmanager. You may be

Hardware Overview
Note: This device is not
intended for use within
close proximity of the
human body. Antenna
installation should provide
for at least a 20 cm
separation from the
operator.
The Helix will work with most dual band cellular antennas with SMA connectors.
Connect antennas directly to the connectors found on the sides of the Helix.
Note: When using a cable to an antenna placed away from the Helix, minimize the length
of your cable. All gain from a more advantageous antenna placement can be lost with a
long cable to the device. Each external antenna used with an extension cable, should be
located 20cm apart from any other antenna.

WAN/Cellular
The WAN/Cellular section allows changes to the cellular connection
and main operating mode of the Helix. Some settings may appear
differently and are dependent on cellular carrier settings.
The default mode is "Cellular". This uses the onboard cellular module
as primary means of connection and enables all other onboard
features. Custom connection settings can be included if they are
supported by the cellular module.
Figure 6-1: ACEmanager: WAN/Cellular
Command
Description
Backhaul Mode
Cellular, WAN failover, IP Passthrough. These are the three operating modes
of the Helix. Cellular mode is the default mode and in this mode the Helix
operates as cellular modem with LAN routing capabilities. WAN failover mode
uses either the cellular modem or an Ethernet WAN link (DSL, cable, office
LAN) to connect to the Internet. The Helix will then manage and switch
between the two connections based on their availability. IP Passthrough
mode will pass the cellular WAN IP address directly through to any client
connected to port 2 of the Helix. This is used in some VPN scenarios or when
a device requires an external IP address. Devices connected to port 1 or Wi-
Fi will still receive DHCP addressing.
Network Credentials
Default or Custom. Default settings are the default cellular data connection
settings in the United States. Selecting Custom settings will show another set
of fields allowing you to use custom settings for specific carrier information.

Set APN (GSM only)
APN or Access Point Name is specific to GSM networks. Custom access
points can be used to create VPN connections or to provide specific routing
functionality. Contact your cellular carrier for more information about how
these work.
Network User ID
Enter the user name needed the authenticate on your APN. This is provided
by your cellular operator.
Network Password
This setting shows up on Helix boxes with GSM and CDMA technology. Fill in
the password that accompanies the custom connection information.
Keepalive IP Address The IP address that the Helix will ping to determine if there is internet
connectivity. By default, this is set to a Sierra Wireless server, but this can be
changed. If the Helix is setup for WAN failover, or any custom cellular settings
(ie Datalink or custom APN), make sure this IP address is accessible.
Keepalive Ping Time
This is the amount of time between keep-alive pings in seconds. This setting
prevents the cellular modem from going into a low power, or hibernation
mode by regularly sending out ICMP pings. By default, this is configured to
3600 seconds or an hour. If the ping fails, the Helix will send an additional
three pings to the specified address. If those pings fail, the Helix will restart
the cellular connection automatically.
WAN Failover
WAN Failover allows the Helix to intelligently manage two Internet connections,
switching from one to the other as needed. After enabling this mode, Helix will
continually test the primary Internet connection. If tests fail, Helix will
automatically switch to the secondary connection while continuing to test the
primary connection and switch back to the primary connection when connectivity
is returned.

If Static mode is selected, this is the IP address of the Helix Box on the secondary network.
If Static mode is selected, this is the netmask of the Helix Box in WAN Failover (primary or
secondary).
Gateway IP

If Static mode is selected, this is the gateway IP address of the that the Helix Box.
If Static mode is selected, this is the primary DNS server that the Helix connects on the
secondary network.
DNS 2
If Static mode is selected, this is the secondary DNS server that the Helix connects on the
secondary network.
Primary Interface
Primary Route IP
Cellular or Ethernet. This determines the cellular module or the Ethernet connection to be
the primary connection.
This is the IP address that Helix continually tests connectivity with. Helix will ping this
address through the primary WAN connection to ensure the primary connection is working.
If a ping to this address fails, Helix will rollover all WAN connectivity to the secondary WAN
connection until it can resume connectivity to this address through the primary connection.
Interval (Secs)
Determines how often the Primary Route IP is tested.
Setup
1. Select WAN Failover from the backhaul mode drop-down menu.
2. Determine whether the Ethernet (WAN) network is DHCP or Static IP based
and fill in information accordingly.
3. Select the primary interface. This should be selected as the most reliable
connection and will be the one that the Helix primarily uses and tests. The
secondary connection will be the connection that the Helix keeps active and

switches to if the primary connection fails. Default primary interface is
Ethernet.
4. If needed, change the Primary Route IP and interval.
5. Click on Apply and reboot the box when prompted.
6. Plug in the Ethernet cable for the WAN connection in to WAN/LAN port of the
Helix.
How it works
When enabled, Helix will ping the Primary Route IP at the interval you have
configured. If one of these pings fails, Helix will immediately send another short
series of pings to that IP address. If these pings also fail, Helix will switch to using
the secondary Internet connection.
While the secondary Internet connection is being used, Helix will continue to ping
the Primary Route IP to determine when the connection is restored. When the
connection is restored, Helix will switch back to the primary connection.
IP Passthrough
IP Passthrough mode will pass the cellular WAN IP address directly through to
any client connected to WWAN/LAN port on the Helix. This may be necessary for
some VPN configurations or other enterprise applications. The Helix can also
continue to provide LAN IP addresses to clients connected through LAN port (or
Wi-Fi with supported devices). However WAN Failover, DMZ, and Port Forwarding
are not available and ACEmanager cannot be reached through port 1. Any client
connected to WWAN/LAN port must be setup with a static IP address and a
gateway address that matches the WWANIP address and gateway address. IP
passthrough works best when the cellular module is setup by the cellular carrier
to receive a public static IP address on the carrier network.

• LAN/WiFi
LAN/WiFi
The LAN/WiFi section displays VLAN configuration parameters, in
ACEmanager.
VLAN stands for virtual LAN. VLANSs help structure the network
growth of companies. A VLAN typically has a cluster of hosts that are
together in a broadcast domain and not based on their physical
location. A difference between VLAN and LAN is that a VLAN allows
devices to be grouped together even when the devices are not
located on the same network switch.
The VLAN implementation with a Helix is more of a VLAN support.
i.e. if there is a switch behind the Helix that supports VLAN, Helix will
forward the packet to the appropriate VLAN segment.
ACEmanager allows the users to reconfigure their network instead of
relocating devices.
Addressing/VLAN

1-11. The Wi-Fi access point on the Helix can use any of 11 channels. If other Wi-Fi
networks are in range and operating on nearby channels, you may be able to avoid
interference by changing to a different Wi-Fi channel.
Security Encryption
type
Open, WEP, WPA. The Helix box supports Wired Equivalent Privacy (WEP) and Wi-Fi
Protected Access/802.11i (WPA and WPA2 Personal and Enterprise). Both protocols will
restrict access to the Helix box and protect data transmitted between the clients and the
device. WPA provides the highest level of security if all of the LAN devices on your network
support this protocol. WPA Enterprise is the follow on wireless security method to WPA that
provides stronger data protection for multiple users and large managed networks. It
prevents unauthorized network access by verifying network users through an
authentication server.
Note: WiFi Default has Shared WEP as an option in the Security Encryption Type field,
while WiFi 2, WiFi 3, and WiFi 4 does not have Shared WEP as an option.

wireless clients on your network.
WEP Passphrase
The default passphrase is 'HelixWEP'. You can enter your own private WEP passphrase to
generate a hex (hexadecimal) key. Treat the passphrase like a password and select one
that is difficult for others to guess. After you enter a new passphrase, click the Apply button
to make the change effective. When logging into Wi-Fi from your computer, enter the hex
key, not the passphrase. Most WEP connections only use the hexadecimal format. The
passphrase is simply used as an easy way for you to create a hex key. You can configure
your own hex key rather than generating one with a passphrase by selecting the 'Custom
Key' option from the drop-down menu. Make sure your hex key only includes 10 or 26 valid
hex digits, created through pairs of characters of 0-9 and/or a-f, with each pair separated by
a colon. For example, 80:3a:c9:95:b8.
WPA/WPA2 Personal
WPA/WPA2 Personal is a higher level of encryption than WEP, requiring a pre

VRRP
VRRP allows multiple routers to act as the default gateway router for a subnet
which reduces the possibility of a single point of failure. This is accomplished by
advertising a single virtual router to connected hosts. The physical router that is
currently handling traffic for the virtual router is designated as the master router.
Routers which are not handling traffic are backup routers.
This switchover occurs in 3 to 10 seconds. While IPsec client connections are
disconnected during this transition, users need only to reconnect without
changing the destination address of their connection profile.

• VPN
VPN
The Helix Box can act as a Virtual Private Network (VPN) client,
providing enterprise VPN access to any device connected to the
Helix RT even when a device has no VPN client capability on its own.
The Helix supports up to two tunneling protocols, IPsec and GRE.
Both can be used at the same time if configured properly.
The Helix also supports split tunnels with one encrypted tunnel and
one open tunnel. A sample server subnet for a split tunnel would be
172.16.1.0/24. Split tunnel VPNs should be setup with care, as a split
tunnel configuration with both an enterprise VPN and access to the
public Internet can inadvertently expose company resources.
This section should give you a general overview of the VPN
capabilities. If you would like specific solution support, refer to the
recommendations and instructions provided with your VPN server
solution.

AirLink Helix User Guide
Command
Description
VPN 1 Type
Tunnel Disabled or IPsec tunnel. Use this option to enable or disable the VPN tunnel. If
custom settings are used, they will be saved and the tunnel can be disabled and re-
enabled without needing to reenter any of the settings. The IPsec VPN employs the IKE
(Internet Key Exchange) protocol to set up a SecurityAssociation (SA) between the Helix
and a Cisco (or Cisco compatible) enterprise VPN server. IPSec consists of two phases to
setup an SA between peer VPNs. Phase 1 creates a secure channel between the Helix
VPN and the enterprise VPN, thereby enabling IKE exchanges. Phase 2 sets up the IPSec
SA that is used to securely transmit enterprise data. For a successful configuration, all
settings for the VPN tunnel must be identical between the Helix VPN and the enterprise
VPN server.
VPN1 Status
Disabled, Not Connected, or Connected. This indicates the current status of the VPN
connection. Use this as part of troubleshooting a VPN connection.
SNTP Server Address The Simple Network Time Protocol Server (SNTP) ensures the clock on the Helix VPN is
synchronized to standard time. The default NTP server is pool.ntp.org. You can specify any
preferred NTP server. Both the VPN server and client must use the same SNTP address.
VPN Gateway
Address
The IP address of the server that this client connects to. This IP address must be open to
connections from the Helix Box.
Remote Subnet (IP
Addr Mask)
The default configuration is 0.0.0.0/0 which will direct all traffic over the GRE tunnel.
Pre-shared Key 1
My Identity
Pre-shared Key (PSK) used to initiate the VPN tunnel.
If these fields are left blank, My Identity will default to the WAN IP address assigned by the
carrier and Peer Identity will default to the VPN Server IP. For a fully qualified domain name
user-FQDN, these values should include a username ([email protected])
Peer Identity
Required in some configurations to identify the client or peer side of a VPN connection.
This defaults to the VPN server IP address.
Negotiation Mode
Main Mode or Aggressive. To operate the onboard VPN under Aggressive mode, enable
this configuration. By default the Helix operates under Main Mode. Aggressive mode offers
increased performance at the expense of security.
IKE Encryption
Algorithm
DES, 3DES, or AES. Determines the type and length of encryption key used to encrypt/
decrypt ESP (Encapsulating Security Payload) packets. 3DES supports 168-bit encryption.
AES (Advanced Encryption Standard) is supports 128 bit encryption.
IKE Authentication
Algorithm
SHA1 or MD5. Can be configured with MD5 or SHA1. MD5 is an algorithm that produces a
128-bit digest for authentication. SHA1 is a more secure algorithm that produces a 160-bit
digest.
IPSec Encryption
Algorithm
DES, 3DES, or AES. Determines the type and length of encryption key used to encrypt/
decrypt ESP (Encapsulating Security Payload) packets. 3DES supports 168-bit encryption.

feature is enabled, one key cannot be derived from another. This ensures previous and
subsequent encryption keys are secure even if one key is compromised.
IPSec Key Group
DH1, DH2, or DH5. Determines how the Helix VPN creates an SA with the VPN server. The
DH (Diffie-Hellman) key exchange protocol establishes pre-shared keys during the phase 1
authentication. Helix supports three prime key lengths, including Group 1 (768 bits), Group
2 (1,024 bits), and Group 5 (1,536 bits).
IPSec SA Life Time
180 to 86400. Determines how long the VPN tunnel is active in seconds. The default value
is 28,800 seconds, or 8 hours.
VPN 2
The Helix can act as a Generic Routing Encapsulation (GRE) endpoint, providing
a means to encapsulate a wide variety of network layer packets inside IP
tunneling packets. With this feature you can reconfigure IP architectures without
worrying about connectivity. GRE creates a point-to-point link between routers on
an IP network.
The VPN 2 section allows configuration of the GRE tunnel on the Helix box.

DMZ IP
IP address of a DMZ. The Helix allows a single client to connect to the
Internet through a demilitarized zone (DMZ). The DMZ is particularly useful
for certain services like VPN, NetMeeting, and streaming video that may not
work well with a NAT router. DMZ host is unavailable if IP passthrough is
enabled.
DMZ Enabled
OFF or ON. Enables or disables the DMZ on the Helix. The Helix allows a
single client to connect to the Internet through a demilitarized zone (DMZ).
Note: All security features are inactive if DMZ is enabled.
Note: Because DMZ traffic does not pass through the NAT router, the DMZ
host is fully exposed to the Internet without the protection of the Helix firewall.
If the DMZ is used, this can present a security risk to the DMZ host client.
