1. CONFIGURATION OVER WEB BROWSER
1. Configuration over web browser
Attention! If the SIM card is not inserted in the router, then wireless transmissions will not
work. The inserted SIM card must have activated GPRS. Insert the SIM card when the router
is switched-off.
For monitoring, configuring and managing the router use web interface, which can be
invoked by entering the IP address of the router into your browser. The default IP address of
the router is 192.168.1.1. Configuration may be performed only by the user "root" with initial
password "root".
The left part of the web interface contains the menu with pages for monitoring (Status),
Configuration,Customization and Administration of the router.
Name and Location items displays the name and location of the router filled in the SNMP
configuration (see SNMP Configuration).
For increased safety of the network managed by the router must be changed the default
router password. If the router’s default password is set, the Change password item is high-
lighted in red.

1. CONFIGURATION OVER WEB BROWSER
After green LED starts to blink it is possible to restore initial settings of the router by press-
ing button RST on front panel. If press button RST, configuration is restored to default and it
is reboot (green LED will be on).
1.1 Secured access to web configuration
To the web configuration can be accessed via a secure HTTPS protocol. In the event
of a default router IP address is a secure router configuration accessed by entering address
https://192.168.1.1 in the web browser. The first approach is the need to install a security cer-
tificate. If your browser reports a disagreement in the domain, this message can be prevented
use the following procedure.
Since the domain name in the certificate is given the MAC address of the router (such
separators are used dashes instead of colons), it is necessary to access the router under this
domain name. For access to the router via a domain name, it is adding a DNS record in the
DNS table, the operating system.
•Editing /etc/hosts (Linux/Unix)
•Editing C:\WINDOWS\system32\drivers\etc\hosts (Windows XP)
•Configuring your own DNS server
In addition to configuring the router with MAC address 00:11:22:33:44:55 is accessed to
secure configuration by typing address https://00-11-22-33-44-55 in the web browser. The first
approach is the need to install a security certificate.
When using self signing certificate must upload your files and http_cert http_key directory
/etc/certs in the router.
1.2 General
A summary of basic information about the router and its activities can be invoked by se-
lecting the General item. This page is also displayed when you login to the web interface.
Information is divided into a several of separate blocks according to the type of router activ-
ity or the properties area – Mobile Connection,Primary LAN,Peripherals Ports and System
Information. If your router is equipped with WIFI expansion port, there is also WIFI section.

In detecting the status of updates DynDNS record are possible following message:
•DynDNS client is disabled.
•Invalid username or password.
•Specified hostname doesn’t exist.
•Invalid hostname format.
•Hostname exists, but not under specified username.
•No update performed yet.
•DynDNS record is already up to date.
•DynDNS record successfully update.
•DNS error encountered.
•DynDNS server failure.
For correct function DynDNS, SIM card of router must have assigned public IP address.
1.8 System Log
In case of any problems with connection to GPRS it is possible to view the system log by
pressing the System Log menu item. In the window, are displayed detailed reports from indi-
vidual applications running in the router. Use the Save Log button to save the system log to a
connected computer. The second button – Save Report – is used for creating detailed report
(generates all support needed information in one file).
The Syslog default size is 1000 lines. After reaching 1000 lines create a new file for storing
system log. After completion of the 1000 lines in the second file, the first file is deleted and
creates a new one.
Program syslogd can be started with two options that modifies its behavior. Option "-s"
followed by decimal number set maximal number of lines in one log file. Option "-r" followed
by hostname or IP address enable logging to remote syslog daemon. In the Linux must be
enabled remote logging on the target computer. Typically running syslogd with the parameter
“-r”. On Windows must be installed the syslog server (for example Syslog Watcher). For
starting syslogd with these options you could modify script "/etc/init.d/syslog" or add lines
"killall syslogd" and "syslogd <options> &" into Startup Script.

1.9 LAN configuration
To enter the network configuration, select the LAN menu item. ETH network set in Primary
LAN configuration, expansion PORT ETH set in Secondary LAN configuration.
Item Description
DHCP Client •disabled – The router does not allow automatic allocation IP address
from a DHCP server in LAN network.
•enabled – The router allows automatic allocation IP address from a
DHCP server in LAN network.
IP address Fixed set IP address of network interface ETH.
Subnet Mask IP address of Subnet Mask.
Bridged •no – The router is not used as a bridge (default)
•yes – The router is used as a bridge
Media type •Auto-negation – The router selects the speed of communication
of network options.
•100 Mbps Full Duplex – The router communicates at 100Mbps, in the
full duplex mode.
•100 Mbps Half Duplex – The router communicates at 100Mbps,
in the half duplex mode.
•10 Mbps Full Duplex – The router communicates at 10Mbps, in the
full duplex mode.
•10 Mbps Half Duplex – The router communicates at 10Mbps, in the
half duplex mode.
Default Gateway IP address of router default gateway. When entering IP address of
default gateway, all packets for which the record was not found in the
routing table, sent to this address.
DNS server IP address of DNS server of router. Address where they are forwarded
to all DNS questions on the router.
Table 11: Configuration of network interface
Default Gateway and DNS Server items are used only if the DHCP Client item is set to a
value disabled and if the Primary or Secondary LAN is selected by Backup routes system as
a default route (selection algorithm is described in section 1.12 Backup Routes).
There can be only one active bridge on the router at the moment. Only parameters DHCP
Client, IP address and Subnet Mask can be used to configure bridge. Primary LAN has got
higher priority in this respect when both interfaces (eth0, eth1) are added to the bridge. Other
interfaces (wlan0 – wifi) can be added (or deleted) to (from) existing bridge at any moment.
Moreover, the bridge can be created on demand of such interfaces but not configured by their
respective parameters.
DHCP server assigns IP address, gateway IP address (IP address of the router) and IP
address of the DNS server (IP address of the router) to the connected clients.
