CONFIGURATION
31
In the second part of window, it is possible to define the DHCP server by checking
the Enable DHCP server option. In the window it is possible to define the beginning
(IP Pool Start) and end (IP Pool End) of the pool of IP addresses that will be assigned to
DHCP clients.
The changes in settings will apply after pressing the Apply button.
The DHCP server assigns to the connected clients IP addresses from the defined
address pool, IP address of the gate and IP address of the primary DNS server. It is important
not to overlap the ranges of the static engaged IP address with the address allotted by the help
of DHCP, or else it is able to achieve a collision of addresses and thereby to create a false
function of the network.
5.8. UMTS/GPRS Configuration
To enter the PPP connection configuration select the PPP menu item. If the Create
PPP connection option is checked, the modem itself automatically tries to establish PPP
connection after switch on. In the window it is possible to define APN, Username, Password
and IP address for both SIM cards, eventually if the first SIM card has set two difference
APN’s.
Attention! If in the UR5 is include the main SIM card which has set two difference
APN’s, second socket for SIM card have not to be in the UR5, otherwise switch to
secondary APN according to rules in web fail.
If the APN field is not filled in, the APN will be automatically assigned by the IMSI code
of the SIM card. If the PLMN (operator number format) is not in the book of APN, then default
APN is “internet“. The mobile operator defines APN. The PLMN parameter is possible to
define in Operator item. Network Type item defines way of data transmition, respectively
Automatic selection according to network availability or UMTS/HSDPA or GPRS/EDGE
technology.
If the IP address field is not filled in, the operator when establishing the connection will
automatically assign the IP address.
The choice Get DNS address from operator is given for easier configuration on client
side; by this choice it is possible to use the web browser. If this field is not filled, the client’s
station has no access to the Internet and it is possible to send data to a known IP address.
If the Check PPP connection option is checked, it has active control of connection over
PPP. The modem will automatically send the ping question to the selected IP address (Ping IP
Address) in periodic time intervals (Ping Interval). It is possible to use as ping IP address for
example DNS server of mobile operator.
