1. Router Configuration Using a Web Browser
Attention! The SPECTRE cellular router will not operate unless the cellular carrier has been
correctly configured and the account activated and provisioned for data communications. For
UMTS and LTE carriers, a SIM card must be inserted into the router. Do not insert the SIM card
when the router is powered up.
You can monitor the status, configuration and administration of the router via the Web interface.
To access the router over the web interface, enter http://xxx.xxx.xxx.xxx into the URL for the
browser where xxx.xxx.xxx.xxx is the router IP address. The modem’s default IP address is
192.168.1.1. The default username is "root" and the default password is "root".
The left side of the web interface displays the menu. You will find links for the Status,
Configuration and Administration of the router.
Name and Location displays the router’s name, location and SNMP configuration (See SNMP
configuration). These fields are user-defined for each router.
For enhanced security, you should change the default password. If the router's default password
is set, the menu item "Change password" is highlighted in red.

If the green LED is blinking, you may restore the router to its factory default settings by pressing
RST on front panel. The configuration will be restored to the factory defaults and the router will
reboot. (The green LED will be on during the reboot.)
1.1. Secured access to web configuration
The Web interface can be accessed through a standard web browser via a secure HTTPS
connection.
Access the web interface by entering https://192.168.1.1 in the web browser. You may receive a
message that there is a problem with the website’s security certificate. If you do, click on
“Continue to this website”. If you wish to prevent this message, you must install a security
certificate into the router.
Since the domain name in the certificate is given the MAC address of the router (such addresses
use dashes instead of colons as separators), it is necessary to access the router under this
domain name. For access to the router via a domain name, a DNS record must be added to the
DNS table in the operating system.
There are three methods to add a domain name to the operating system:
Editing /etc/hosts (Linux/Unix)
Editing C:\WINDOWS\system32\drivers\etc\hosts (Windows XP)
Configuring your own DNS server
You must then add a security certificate to the web server on the router. When using a
self-signed certificate, you must upload your files to the certs directory /etc/certs in the router.

1.3. DHCP status
Information about the DHCP server can be accessed by selecting the DHCP status. The
DHCP server provides automatic configuration of the client devices connected to the router. The
DHCP server assigns each device an IP address, subnet mask, default gateway (IP address of
router) and DNS server (IP address of router).
For each client in the list, the DHCP status window displays the following information.

If a neighboring cell is highlighted in red, there is a risk that the router may repeatedly
switch between the neighboring cell and the primary cell. This can affect the performance of the
router. To prevent this, re-orient the antenna or use a directional antenna.
The next section of this window displays historical information about the quality
of the cellular WAN connection during each logging period. The router has standard intervals
such as the previous 24 hours and last week and also includes information one user-defined

1.5. IPsec status
Selecting the IPsec option in the status menu of the web page will bring up the
information for any IPsec Tunnels that have been established. Up to 4 IPsec tunnels can be
created. If no IPsec tunnels are configured, the status will show that “IPsec is disabled”.
If an IPsec tunnel is established, the router will show “IPsec SA established”
(highlighted in red) in the IPsec status information.
Fig. 5: IPsec status
1.6. DynDNS status
The router supports DynamicDNS using a DNS server on www.dyndns.org. If Dynamic
DNS is configured, the status can be displayed by selecting menu option DynDNS. Refer to
www.dyndns.org for more information on how to configure a Dynamic DNS client.
Fig. 6: DynDNS status
DynDNS client is disabled.
Invalid username or password.

1.7. System log
Use the System Log menu item to view the router system log. The system log contains
helpful information on the operation of the router. Only the most recent information is shown on
the screen but older log entries can be viewed by saving the system log to a file and opening it
with a text editor. The Save button allows you to save the system log to a file. The system log is
cleared when the unit re-boots.
Fig. 7: System log
The Syslog default size is 1000 lines. When the system log reaches the maximum size, it
is deleted and a new log file is started.
The program syslogd can be run on the router to configure the system log. The syslogd
option "-s" followed by decimal number will set the maximum number of lines in the log file. The
"-r" option followed by the hostname or IP address will enable logging to a syslog daemon on a
remote computer. On remote Linux machines, the syslog daemon is enabled by running syslogd
with the parameter “-r”. On remote Windows machines, a syslog server such as Syslog Watcher
must be installed.
To enable remote logging when the router powers up, modify the script
"/etc/init.d/syslog" or add the commands "killall syslogd" and "syslogd <options>" into the
startup script.
The following example shows how to send syslog information to a remote server at
192.168.2.115 on startup.

1.8. LAN configuration
Select the LAN menu item to enter the network configuration for the Ethernet ports. The
main Ethernet port, ETH, is setup in the Primary LAN section. If the router has additional
Ethernet ports (PORT1 or PORT2), they are configured under the Secondary LAN section. For
routers with 2 additional Ethernet ports, PORT1 and PORT2 are automatically bridged together.

100 Mbps Half Duplex - The router communicates at 100Mbps,
in half-duplex mode.
10 Mbps Full Duplex - The router communicates at 10Mbps, in full-
duplex mode.
10 Mbps Half Duplex - The router communicates at 10Mbps, in

Default
Gateway
IP address of Default gateway for the router. When entering IP address
of default gateway, all packets for which the record was not found
in the routing table are sent to this address.
DNS server
IP address of the primary DNS server for the router.
Table 9: Configuration of network interface
The DHCP server assigns the IP address, default gateway IP address, and IP address of
the DNS server to the connected DHCP clients.
The DHCP server supports both static and dynamic assignment of IP addresses. In
Dynamic IP address assignment, the DHCP server will assign a client the next available IP
address from the allowed IP address pool. Once the lease time on an IP address has expired, the
DHCP server is free to re-assign that IP to another client.

IP Pool Start
Starting IP address of the range allocated to the DHCP clients.
IP Pool End
Ending IP address of the range allocated to the DHCP clients.
Lease time
Time in seconds that the IP address is reserved before it can be re-used.
Table 10: Configuration of a dynamic DHCP server
The DHCP server can also assign a Static IP address to a client. The MAC address of
the client must be configured in the MAC address table along with the desired IP address. Up to
6 static IP addresses are supported. Do not overlap the static IP addresses with the addresses
