SmartFlex
1. Basic Information
SmartFlex is LTE cellular router designed for communication across cellular networks us-
ing LTE, HSPA+, UMTS, EDGE or GPRS technology. Data transfer speed is up to 100 Mbps
(download) and up to 50 Mbps (upload). The router is an ideal solution for the wireless con-
nection of traffic and security camera systems, individual computers, LANs, automatic teller
machines (ATM), other self-service terminals, and many other devices.
SmartFlex SR300 version of the router (LAN) is an ideal device for the realization of a
secure connection of two local area networks (LANs). Interconnection is carried out using two
ETHERNET 10/100 interfaces and secure tunnel (IPsec,OpenVPN,L2TP). The other equally
important ways to use this router is to connect any device with RS232, RS485 or RS422 serial
interface to the local network (LAN). For this purpose, SmartFlex SR300 router is equipped
with two ETHERNET 10/100 ports and other interfaces based on the version of the router
chosen by the user.
1.1 Standard Equipment
Standard features include the LTE cellular module (with three antenna connectors – for
main, diversity and GPS antenna), two Ethernet 10/100 ports, one USB 2.0 Host port, two
binary inputs, one output (I/O connector), and two SIM card readers for 3 V and 1.8 V SIM
cards. The router also has microSD memory card reader that increases the router’s storage
space by up to 64 GB when using SDXC card or up to 32 GB when using SDHC cards.
1.2 Optional Features
If desired, the router can be configured with these optional interfaces. Note that routers
cannot be retrofitted with these interfaces feature at some point in the future. See the router’s
technical manual for details on versions and possible combinations of interfaces.
•Version with the WiFi module. WiFi antenna connector is on the front panel.
•Version with three more Ethernet ports (switched).
•Version with RS232 interface.
•Version with combination of galvanically separated RS232 and RS485 interfaces.
•Version with combination of galvanically separated RS232, RS485 and Ethernet with
stronger isolation.
•Version with SmartMesh IP wireless interface (DUST technology) – the router can serve
as SmartMesh IP gateway for DUST nodes (motes).
•The router can be provided in either plastic or metal casing, depending upon the cus-
tomer’s requirements.

SmartFlex
1.3 Advantages in Relation to v2 Concept Routers
The most considerable improvement in this new generation of routers is that they contain
a CPU that is four times more powerful than the previous generation, providing significantly
higher throughput and much faster encryption speeds. The router can also boasts a substan-
tially larger memory (512 MB RAM and 256 MB flash). As previously mentioned, the storage
space can be further increased using a memory card. The fact that the router supports POE
(Power over Ethernet) is also significant. This means that it is possible to power the device
over a data network cable without the use of a dedicated power cable. The customer The cus-
tomer can choose a setup to best meet their requirements, from either "v3" router supporting
PSE mode (Power Source Equipment), PD mode (Powered Device) or a router which does
not support POE.
1.4 Configuration
Configuring SmartFlex routers is made easy by name and password protected web inter-
face. The interface provides detailed statistics about router activities, signal strength, system
logs and more. The router supports both IPv4 and IPv6 protocols, the creation of secure VPN
tunnels using technologies that include IPsec,OpenVPN and L2TP. The router also supports
DHCP,NAT,NAT-T,DynDNS client,NTP,VRRP, control by SMS, backup of primary connec-
tion, multiple WANs, RADIUS authentication over WiFi and many other functions.
Additional diagnostic features designed to ensure continuous communication include au-
tomatic inspection of PPP connections, an automatic restart feature in case a connection is
lost, and a hardware watchdog that monitors the status of the router. Using a start up script
window, users can insert Linux scripts for various actions. Users may insert multiple scripts
and the router can switch between configurations as needed. Examples would include using
SMS or checking the status of the binary input. SmartFlex routers can automatically update
their configurations and firmware from a central server, allowing for mass reconfiguration of
multiple routers at the same time.
1.5 Configuration Options
Routers can be configured via web browser or Secure Shell (SSH). Configuration via Web
Browser is described in this Configuration Manual. Commands and scripts applicable in con-
figuration using SSH are described in Commands and Scripts for v2 and v3 Routers – Ap-
plication Note [1]. Technical parameters and a full description of the router can be found in
the User Manual of your router. You can also use additional software – communication VPN
server SmartCluster [2] and software for router monitoring R-SeeNet [3, 4].
1.6 IPv6 Support
There is independent IPv4 and IPv6 dual stack configuration implemented in the router’s
firmware. This means that you can configure traffic through both IP protocols independently
2

SmartFlex
and both are supported. Additional EUI-64 IPv6 addresses of network interfaces are generated
automatically by standard methods. There is a NAT64 internal gateway network interface for
automatic translation between IPv6 and IPv4 (see Chapter 3.5 for more information). This
gateway works together with DNS64 seamlessly (for domain names translation).
For cellular IPv6 connection see Mobile WAN Configuration in Chapter 4.3.1. For IPv6 LAN
configuration see LAN Configuration in Chapter 4.1, DHCPv6 server/client is also supported.
IPv4 is the default, but IPv6 can be enabled or used with all features and protocols in the router,
except for non-secured tunnels GRE, L2TP and PPTP, and VRRP. Using the secured tunnels
OpenVPN and IPsec it is possible to run IPv6 traffic through an IPv4 tunnel and vice versa.
The configuration forms for NAT,Firewall and Up/Down Scripts are completely separate for
the IPv4 and IPv6 stacks. ICMPv6 protocol is also supported. IPv6 configuration is covered in
each following Chapter when possible.
1.7 This Configuration Manual Describes
•Configuration of the router item by item according to the web interface (chapters 3to 6).
•Configuration in typical situations examples (chapter 7):
–Access to the Internet from LAN (Local Area Network) via mobile network, Ch. 7.1.
–Backed up access to the Internet (from LAN), Ch. 7.2.
–Secure networks interconnection or using VPN (Virtal Private Network), Ch. 7.3.
–Serial Gateway (connection of serial devices to the Internet), Ch. 7.4

2. Access to the Web Configuration
Attention! Wireless transmissions work only when you activate the SIM card for data
traffic and insert it into the router. Remove the power source before inserting the SIM
card.
You may use the web interface to monitor, configure and manage the router. To do so,
enter the router’s IP address in your browser. The default address is 192.168.1.1. Only ac-
cess via secured HTTPS protocol is permitted. So the syntax for the IP address must be
https://192.168.1.1. When accessing the router for the first time you will need to install a se-
curity certificate if you don’t want the browser to show you a domain disagreement message.
To avoid receiving domain disagreement messages, follow the procedure described in the
following subchapter.
The default username is "root". The default password is "root". Change the default
Figure 1: Example of the Web Configuration
4

SmartFlex
password as soon as possible!
For increased security of the network connected to the router, change the default router
password. When the default password of the router is still active, the Change password
title is highlighted in red.
When you successfully enter login information on the login page, web interface will be
displayed. The left side of the web interface contains a menu tree with sections for monitor-
ing (Status), configuration (Configuration), customization (Customization) and administration
(Administration) of the router.
Name and Location items in the right upper corner display the name and location of the
router in the SNMP configuration (see 4.16.4). These fields are user-defined for each router.
After the green LED starts to blink you may restore the initial router settings by pressing
the reset (RST ) button on the back panel. If the reset button is pressed, all configuration will
revert to factory defaults and the router will reboot (the green LED will be on during the reboot).
2.1 Certificates and Preventing the Security Message
There is the self-signed HTTPS certificate in the router. If you want to use your own
certificate (e.g. in combination with the dynamic DNS service), you need to replace the
/etc/certs/https_cert and /etc/certs/https_key files in the router.
HTTPS certificate creation in the router was updated since FW 5.3.5 to be more secure.
Existing HTTPS certificates on already manufactured routers will not be automatically
upgraded with the firmware upgrade! You can upgrade HTTPS certificate by deleting
files /etc/certs/https* in the router (e.g. via SSH). The certificates will be re-created auto-
matically during the next router’s start.
If you decide to use the self-signed certificate in the router to prevent the security message
(domain disagreement) from pop up every time you log into the router, you can take the fol-
lowing steps. Note: You will have to use the domain name based on the MAC address of the
router and it is not guaranteed to work with every combination of an operating system and a
browser.
•Add the DNS record to your DNS system: Edit /etc/hosts (Linux/Unix OS) or
C:\WINDOWS\system32\drivers\etc\hosts (Windows OS) or configure your own DNS
server. Add a new record with the IP address of your router and the domain name
based of the MAC address of the router (MAC address of the first network interface seen
in Network Status in the Web interface of the router.) Use dash separators instead of
colons. Example: A router with the MAC address 00:11:22:33:44:55 will have a domain
name 00-11-22-33-44-55.
5

SmartFlex
•Access the router via the new domain name address (E.g. https://00-11-22-33-44-55).
If you see the security message, add an exception so the next time the message will
not pop up (E.g. in Firefox Web browser). If there is no possibility to add an exception,
export the certificate to the file and import it to your browser or operating system.

3. Status
3.1 General Status
Selecting the General item will open a screen displaying a summary of basic information
about the router and its activities. This page is also displayed when you login to the web
interface. Information is divided into several sections, based upon the type of router activity or
the properties area: Mobile Connection,Primary LAN,Secondary LAN,Peripheral Ports and
System Information. If the router is in the Ethernet switch or RS232-RS485-ETH version, there
will be a Tertiary LAN section. If the router is WiFi equipped, there will be a WiFi section.
IPv6 Address item can show multiple different addresses for one network interface. This is
standard behavior since an IPv6 interface uses more addresses. The second IPv6 Address
showed after pressing More Information is automatically generated EUI-64 format link local
IPv6 address derived from MAC address of the interface. It is generated and assigned the first
time the interface is used (e.g. cable is connected, Mobile WAN connecting, etc.).
