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 highlighted in red.

After green LED starts to blink it is possible to restore initial settings of the router by pressing 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 certiﬁcate. 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 https_cert https_key directory /etc/certs in the router.

1.10 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 individual 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.

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 1.17 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. If these values are ﬁlled-in by the user in the conﬁguration form, they are preferred.

DHCP server supports static and dynamic assignment of IP addresses. Dynamic DHCP server assigns clients IP addresses from a deﬁned address space. Static DHCP assigns IP addresses that correspond to the MAC addresses of connected clients.

• 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.

1.12 VRRP conﬁguration

To enter the VRRP conﬁguration select the VRRP menu item. VRRP protocol (Virtual Router Redundancy Protocol) is a technique, by which it is possible to forward routing from main router to backup router in the case of the main router failure. If the Enable VRRP is checked, then it is possible to set the following parameters.

Item Description

Virtual Server IP Address This parameter sets virtual server IP address. This address

should be the same for both routers. A connected device sends its data via this virtual address.

Virtual Server ID Parameter Virtual Server ID distinguishes one virtual router

on the network from others. Main and backup routers must use the same value for this parameter.

Host Priority The router, with higher priority set by the parameter Host

Priority, is the main router. According to RFC 2338 the main router has the highest possible priority - 255. The backup router has priority in range 1 ? 254 (init value is 100). The priority value equals 0 is not allowed.

Table 17: VRRP conﬁguration

It is possible to set Check connection ﬂag in the second part of the window. The currently active router (main/backup) will send testing messages to deﬁned Ping IP Address at periodic time intervals (Ping Interval) with setting time of waiting for answer (Ping Timeout). The function check connection is used as a supplement of VRRP standard with the same ﬁnal result. If there are no answers from remote devices (Ping IP Address) for a deﬁned number of probes (Ping Probes), then connection is switched to the other line.

Item Description

Ping IP Address Destinations IP address ping queries. Address can not specify as

domain name.

Ping Interval Time intervals between the outgoing pings.

Ping Timeout Time to wait to answer.

Ping Probes Number of failed ping requests, after which the route is considered

to be impassable.

Table 18: Check connection

Ping IP address is possible to use for example a DNS server of mobile operator as a test message (ping) IP address.

There’s an additional way for evaluating the state of the active line. It is activated by selecting Enable trafﬁc monitoring parameter. If this parameter is set and any packet different from ping is sent to the monitored line, then any answer to this packet is expected for Ping

1.13 Mobile WAN conﬁguration

This item is not available for mdex Router MX700.

The form for conﬁguration of a connection to the mobile network can be invoked by selecting the Mobile WAN item in the main menu of the router web interface.

1.13.1 Connection to mobile network

If the Create connection to mobile network item is selected, the router automatically tries to establish connection after switching-on.

Item Description

APN Network identiﬁer (Access Point Name)

Tips for working with the Mobile WAN conﬁguration form:

• If the size is set incorrectly, data transfer may not be succeeded. By setting a lower MTU it occurs to more frequent fragmentation of data, which means higher overhead and also the possibility of damage of packet during defragmentation. On the contrary, the higher value of MTU can cause that the network does not transfer the packet.

• If the IP address ﬁeld is not ﬁlled in, the operator automatically assigns the IP address when it is establishing the connection. If ﬁlled IP address supplied by the operator, router accelerate access to the network.

• If the APN ﬁeld is not ﬁlled in, the router automatically selects the APN by the IMSI code of the SIM card. If the PLMN (operator number format) is not in the list of APN, then default APN is "internet". The mobile operator deﬁnes APN.

• If the word blank is ﬁlled in the APN ﬁeld, router interprets APN as blank.

ATTENTION:

• If only one SIM card is plugged in the router (router has one slot for a SIM card), router switches between the APN. Router with two SIM cards switches between SIM cards.

• Correct PIN must be ﬁlled. For SIM cards with two APN?s there will be the same PIN for both APN‘s. Otherwise the SIM card can be blocked by false SIM PIN.

Items marked with an asterisk must be ﬁlled in only if this information is required by the

operator (carrier).

In case of unsuccessful establishing a connection to mobile network is recommended to check the accuracy of entered data. Alternatively, try a different authentication method or network type.

1.13.2 DNS address conﬁguration

The DNS Settings item is designed for easier conﬁguration on the client side. When this item is set to the value get from opertor router makes an attempt to automatically get an IP address of the primary and secondary DNS server from the operator. By way of contrast, set

manually option allows you to set IP addresses of Primary DNS servers manually (using the DNS Server item).

1.13.3 Check connection to mobile network conﬁguration

If the Check Connection item is set to enabled or enabled + bind, checking the connection to mobile network is activated. Router will automatically send ping requests to the speciﬁed domain or IP address (Ping IP Address item) in regular time interval (Ping Interval). In case of unsuccessful ping, a new one will be sent after ten seconds. If it fails to ping the IP address of three times in a row, the router terminates the current connection and tries to establish new

ones. Checking can be set separately for two SIM cards or two APNs. As a ping address can be used an IP address for which it is certain that it is still functional and is possible to send ICMP ping (e.g. DNS server of operator).

In the case of the enabled option ping requests are sent on the basis of routing table. Thus, the requests may be sent through any available interface. If you require each ping request to be sent through the network interface, which was created on the occasion of establishing a connection to the mobile operator, it is necessary to set the Check Connection item to enabled + bind. The disabled variant deactivates checking the connection to mobile network.

Item Description

Ping IP Address Destinations IP address or domain name of ping queries.

Ping Interval Time intervals between the outgoing pings.

Table 20: Check connection to mobile network conﬁguration

If the Enable Trafﬁc Monitoring option is selected, then the router stops sending ping ques- tions to the Ping IP Address and it will watch trafﬁc in connection to mobile network. If this connection is without trafﬁc longer than the Ping Interval, then the router sends ping questions to the Ping IP Address.

Attention! The feature of check connection to mobile network is necessary for uninterrupted operation.

1.13.4 Data limit conﬁguration

Item Description

Data limit With this parameter you can set the maximum expected amount

of data transmitted (sent and received) over GPRS in one billing period (month).

Warning Threshold Parameter Warning Threshold determine per cent of Data Limit in

the range of 50% to 99%, which if is exceeded, then the router sends SMS in the form Router has exceeded (value of Warning Threshold) of data limit.

Accounting Start Parameter sets the day of the month in which the billing cycle

starts SIM card used. Start of the billing period deﬁnes the operator, which gives the SIM card. The router begin to count the transferred data since that day.

Table 21: Data limit conﬁguration

If parameters Switch to backup SIM card when data limit is exceeded and switch to default

SIM card when data limit isn’t exceeded (see next subsection) or Send SMS when datalimit is exceeded (see SMS conﬁguration) are not selected the data limit will not count.

1.13.5 Switch between SIM cards conﬁguration

At the bottom of conﬁguration it is possible to set rules for switching between two APN?s on the SIM card, in the event that one SIM card is inserted or between two SIM cards, in the event that two SIM cards are inserted.

Item Description

Default SIM card This parameter sets default APN or SIM card, from which it will try

to establish the connection to mobile network. If this parameter is set to none, the router launches in ofﬂine mode and it is necessary to establish connection to mobile network via SMS message.

Backup SIM card Deﬁnes backup APN or SIM card, that the router will switch the

deﬁning one of the following rules.

Table 22: Default and backup SIM conﬁguration

If parameter Backup SIM card is set to none, then parameters Switch to other SIM card

when connection fails, Switch to backup SIM card when roaming is detected and switch to default SIM card when home network is detected and Switch to backup SIM card when data limit is exceeded and switch to default SIM card when data limit isn’t exceeded switch the

router to off-line mode.

Item Description

Switch to other SIM card when connection fails

Switch to backup SIM card when roaming is detected and switch to default SIM card when home network is detected

Switch to backup SIM card when data limit is exceeded and switch to default SIM card when data limit isn’t exceeded

If connection to mobile network fails, then this parameter ensures switch to secondary SIM card or secondary APN of the SIM card. Failure of the connection to mobile network can occur in two ways. When I start the router, when three fails to establish a connection to mobile network. Or if it is checked Check the connection to mobile network, and is indicated by the loss of a connection to mobile network.

In case that the roaming is detected this parameter enables switching to secondary SIM card or secondary APN of the SIM. If home network is detected, this parameter enables switching back to default SIM card.

For proper operation, it is necessary to have enabled roaming on your SIM card!

This parameter enables switching to secondary SIM card or secondary APN of the SIM card, when the data limit of default APN is exceeded. This parameter also enables switching back to default SIM card, when data limit is not exceeded.

In this example there is more equipment connected behind the router, using a Switch. Every device connected behind the router has its own IP address and this is the address to ﬁll in the Server IP Address ﬁeld in the NAT conﬁguration. These devices are all communicating on the port 80, but you can set the Port Forwarding in the NAT conﬁguration ? see Figure 31 ? Public Port and Private Port ﬁelds. It is now conﬁgured to access 192.168.1.2:80 socket behind the router when accessing 10.0.0.1:81 from the Internet and so on. If you send the ping request to the public IP address of the router (10.0.0.1), the router will respond as usual (not forwarding). If you access the IP address 10.0.0.1 in the browser (it is port 80), the router’s Web interface will come up since Enable remote HTTP access on port 80 is checked.

Encapsulation Mode IPsec mode (according to the method of encapsulation) – You

can choose tunnel (entire IP datagram is encapsulated) or trans- port (only IP header).

NAT traversal If address translation is used between two end points of the tun-

nel, it needs to enable NAT Traversal.

IKE Mode Deﬁnes mode for establishing connection (main or aggressive).

If the aggressive mode is selected, establishing of IPsec tunnel will be faster, but encryption will set permanently on 3DES-MD5.

We recommend not to use aggressive mode due to a lower security!

IKE Algorithm Way of algorithm selection:

• auto – encryption and hash alg. are selected automatically

• manual – encryption and hash alg. are deﬁned by the user

IKE Encryption Encryption algorithm – 3DES, AES128, AES192, AES256

IKE Hash Hash algorithm – MD5, SHA1, SHA256, SHA384 or SHA512

IKE DH Group Difﬁe-Hellman groups determine the strength of the key used in

the key exchange process. Higher group numbers are more secure, but require additional time to compute the key. Group with higher number provides more security, but requires more processing time.

ESP Algorithm Way of algorithm selection:

• auto – encryption and hash alg. are selected automatically

• manual – encryption and hash alg. are deﬁned by the user

IPsec supports the following types of identiﬁers (ID) of both tunnel sides (Remote ID and

Local ID items):

• IP address (e.g. 192.168.1.1)

• DN (e.g. C=CZ,O=Conel,OU=TP,CN=A)

• FQDN (e.g. @director.conel.cz) – in front of FQDN must always be @

• User FQDN (e.g. [email protected])

The certiﬁcates and private keys have to be in PEM format. As certiﬁcate it is possible to

use only certiﬁcate which has start and stop tag certiﬁcate.

Random time, after which it will re-exchange of new keys are deﬁned:

Lifetime - (Rekey margin + random value in range (from 0 to Rekey margin * Rekey Fuzz/100))

By default, the repeated exchange of keys held in the time range:

• Minimal time: 1h - (9m + 9m) = 42m

• Maximal time: 1h - (9m + 0m) = 51m

When setting the times for key exchange is recommended to leave the default setting in which tunnel has guaranteed security. When set higher time, tunnel has smaller operating costs and smaller the safety. Conversely, reducing the time, tunnel has higher operating costs and higher safety of the tunnel.

1.34 Automatic update conﬁguration

In the Automatic update item it is possible to set the automatic conﬁguration update. This choice enables the router to download the conﬁguration and the newest ﬁrmware from the server automatically. The conﬁguration and ﬁrmware ﬁles are stored on the server. To prevent possible unwanted manipulation of the ﬁles, downloaded ﬁle (tar.gz format) is controlled. At ﬁrst, the format of the downloaded ﬁle is checked. Then the type of architecture and each ﬁle in the archive (tar.gz ﬁle) is controlled.

By Enable automatic update of conﬁguration it is possible to enable automatic conﬁguration update.

By Enable automatic update of ﬁrmware it is possible to enable ﬁrmware update.

Item Description

Source Where the router will download the ﬁrmware and conﬁguration from:

• HTTP(S)/FTP(S) server – updates are downloaded from the Base URL address below. Used protocol is speciﬁed by that address: HTTP, HTTPS, FTP or FTPS.

• USB ﬂash drive – Router ﬁnds current ﬁrmware or conﬁguration in the root directory of the connected USB device.

• Both – looking for the current ﬁrmware or conﬁguration from both sources.

Base URL Enter the base part of the domain or IP address to download the up-

dates from. Specify the communication protocol by the address (HTTP, HTTPS, FTP or FTPS).

Unit ID Name of conﬁguration (name of the ﬁle without extension). If the Unit

ID is not ﬁlled, the MAC address of the router is used as the ﬁlename (the delimiter colon is used instead of a dot.)

Update Hour Use this item to set the hour (range 1-24) when the automatic update

will be performed every day. If the time is not speciﬁed, automatic update is performed ﬁve minutes after turning on the router and then every 24 hours. If the detected conﬁguration ﬁle is different from the running one, it is downloaded and the router is restarted automatically to make it run.

Table 74: Automatic update conﬁguration

The conﬁguration ﬁle name is from parameter Base URL, hardware MAC address of ETH0 interface and cfg extension. Hardware MAC address and cfg extension is connected automatically and it isn?t needed to enter this. By parameter Unit ID enabled it deﬁnes the concrete conﬁguration name which will be download to the router. When using parameter Unit ID, hardware MAC address in conﬁguration name will not be used.

The ﬁrmware ﬁle name is from parameter Base URL, type of router and bin extension.

It is necessary to load two ﬁles (.bin and .ver) to the HTTP(S)/FTP(S) server. If there is uploaded only the .bin ﬁle and the HTTP server send wrong answer 200 OK (instead of expected 404 Not Found) when the device try to download the nonexistent .ver ﬁle, then there is a high risk that the router will download the .bin ﬁle over and over again.

The following examples ﬁnd if there is a new ﬁrmware or conﬁguration each day at 1:00 in the morning. The following example is for the MX720 type of router.
