SmartFlex
7. Configuration in Typical Situations
Although Advantech B+B SmartWorx routers have wide variety of uses, they are commonly
used in the following ways. All the examples below are for IPv4 networks.
These examples are not suitable for SmartFlex SR300 router (no cellular module).
7.1 Access to the Internet from LAN
Figure 85: Access to the Internet from LAN – sample topology
In this example, a LAN connecting to the Internet via a mobile network, the SIM card with
a data tariff has to be provided by the mobile network operator. This requires no initial con-
figuration. You only need to place the SIM card in the SIM1 slot (Primary SIM card), attach
the antenna to the ANT connector and connect the computer (or switch and computers) to
the router’s eth0 interface (LAN). Wait a moment after turning on the router. The router will
connect to the mobile network and the Internet. This will be indicated by the LEDs on the front
panel of the router (WAN and DAT ).
Additional configuration can be done in the LAN and Mobile WAN items in the Configura-
tion section of the web interface.
LAN configuration The factory default IP address of the router’s eth0 interface is in the form
of 192.168.1.1. This can be changed (after login to the router) in the LAN item in the Configura-
tion section. (See Figure 86.) In this case there is no need of any additional configuration. The
DHCP server is also enabled by factory default (so the first connected computer will get the
192.168.1.2 IP address etc.). Other configuration options are described in the Chapter 4.1.
