Applications and functions
1
The SINAUT MD741-1 provides a wireless connection to the Internet or to a private network. The SINAUT MD741-1 can provide this connection in any location where a GSM network (Global System for Mobile Communication = mobile phone network) is available which provides the services EGPRS (Enhanced General Packet Radio Service = EDGE) or GPRS (General Packet Radio Service). A precondition for this is a SIM card of a GSM network operator with the appropriate services activated.
The SINAUT MD741-1 thus links a locally connected application or entire networks to the Internet via wireless IP connections. It is also possible to connect directly to an intranet, to which in turn the external remote stations are connected.
The SINAUT MD741-1 can establish a VPN (Virtual Private Network) between a locally connected application / a network and an external network, and can protect this connection against access by third parties through the use of IPsec (Internet Protocol Security).
In order to perform these tasks in the scenarios described, the device combines the following functions:
EDGE modem for flexible data communication via EGPRS or GPRS
Firewall for protection against unauthorized access. The dynamic packet filter
examines data packets based on their source and destination addresses (stateful inspection firewall) and blocks undesirable data traffic (anti-spoofing)
The SINAUT MD741-1 can establish via the wireless IP connections a VPN Virtual Private Network) between the locally connected application or network and en external network and can protect this connection by IPsec (Internet Protocol Security) against unwanted access by third parties.

Configuration of the router and firewall functions is carried out locally or remotely via the Web-based administration interface of the SINAUT MD741-1.
Remote configuration
Remote configuration via HTTPS or CSD access is only possible if the SINAUT MD741-1 is configured for remote access. In this case proceed exactly as described in Chapter 8.
Configuration via the local interface
The preconditions for configuration via the local interface are:
The computer (Admin PC) that you use to carry out configuration must be
either connected directly to the Ethernet jack of the SINAUT MD741-1 via a network cable or it must have direct access to the SINAUT MD741-1 via the local network.
The network adapter of the computer (Admin PC) that you use to carry out
configuration must have the following TCP/IP configuration:
IP address: 192.168.1.2
Subnet mask: 255.255.255.0
Instead of the IP address 192.168.1.2 you can also use other IP addresses from the range 192.169.1.x.
If you also wish to use the Admin PC to access the external network via the
SINAUT MD741-1, the following additional settings are necessary:
Standard gateway: 192.168.1.1
Preferred DNS server: Address of the domain name server

Enter the following values in order to get to the Web user interface of the SINAUT MD741-1:
IP address: 192.168.1.2 Subnet mask: 255.255.255.0
In addition, enter the following values if you want to use the Admin PC to access the external network via the SINAUT MD741-1:
Standard gateway: 192.168.1.1 Preferred DNS server: 192.168.1.1
Preferred DNS server
If you call up addresses via a domain name (e.g. www.neuhaus.de), then you must refer to a domain name server (DNS) to find out what IP address is behind the name. You can define the following as the domain name server:
The DNS address of the network operator,
or
The local IP address of the SINAUT MD741-1, as long as it is configured for
breaking out host names into IP addresses
(see Chapter 4.3; Factory setting).
To define the domain name server in the TCP/IP configuration of your network adapter, proceed as described above.
3.2 Establishing a configuration connection
Setting up a Web browser
Proceed as follows:
1. Launch a Web browser.
(e.g. MS Internet Explorer Version 7 or later or Mozilla Firefox Version 2 or later; the Web browser must support SSL (i.e. HTTPS).)
2. Make sure that the browser does not automatically dial a connection when it is launched.
In MS Internet Explorer, make this setting as follows: Menu Tools, Internet
Options..., tab Connections: Under Dial-up and VPN Settings, make sure that Never dial a connection is activated.

Calling up the start page of the SINAUT MD741-1
3. In the address line of the browser, enter the address of the SINAUT MD741-1 in full. In the factory settings this is:
https://192.168.1.1
Result: A security message appears. In Internet Explorer 7, for example, this one:
Figure 3-2 Confirming the security message
4. Acknowledge the corresponding safety message with "Continue loading this page …"
Note
Because the device can only be administered via encrypted access, it is delivered with a self-signed certificate. In the case of certificates with signatures that the operating system does not know, a security message is generated. You can display the certificate. It must be clear from the certificate that it was issued for SIEMENS AG. The Web user interface is addressed via an IP address and not using a name, which is why
the name specified in the security certificate, is not the same as the one in the
certificate.
Entering the user name and password
5. You will be asked to enter the user name and the password:

Figure 3-3 Enter user name and password
The factory setting is:
User name: admin Password: sinaut
Note
You should change the password in any event. The factory setting is general knowledge and does not provide sufficient protection. Chapter 3.7 contains a description of how to change the password.
The start page is displayed
After the user name and password are entered, the start page of the SINAUT MD741-1 appears in the Web browser with an overview of the operating state, see Chapter 3.3.
The start page is not displayed
If after several tries the browser still reports that the page cannot be displayed, try the following:
Check the hardware connection. On a Windows computer, go to the DOS
prompt (Menu Start, Programs, Accessories, Command Prompt) and enter the
following command:
ping 192.168.1.1

If a return receipt message for the 4 packets that were sent out does not appear within the specified time period, check the cable, the connections and the network card.
Make sure that the browser does not use a proxy server. In MS Internet
Explorer (Version 7.0), make this setting as follows: Menu Tools, Internet Options..., tab Connections: Under LAN Settings, click on the Settings... button, then in the dialog box Settings for local network (LAN), make sure that under Proxy Server the entry Use proxy server for LAN is not activated.
If other LAN connections are active on the computer, deactivate them for the
duration of the configuration process.
Under the Windows menu Start, Connect To ..., Show All Connections… ,
under LAN or High-Speed Internet right-click on the connection concerned and
select Deactivate in the pop-up menu.
Enter the address of the SINAUT MD741-1 with a slash:
