Scenario 1:
The application is connected locally direct to the SINAUT MD740-1: e.g. statement
printer, notebook or PC. This application uses the SINAUT MD740-1 in order to have
secure access to a remote LAN as if it were connected direct to the LAN.
The remote site is a computer in a corporate network. The network, protected by a VPN
router with firewall, is connected to the GPRS network or the Internet and has a known
or definable IP address.
Scenario 2:
The remote site is another SINAUT MD740-1.

1.1 To be able to use the SINAUT MD740-1...
you require... •a subscriber contract with a GSM network operator (e.g. TD1,
Vodafone, E-Plus, O2) that supports GPRS
•release of the GPRS for the user in question by the network
operator
1.2 IP address of the remote site
In order that a SINAUT MD740-1 can actively establish a VPN connection the remote
site must have a fixed IP address (an IP address consists of a maximum of 4 numbers,
separated by dots, which can each have up to three digits, e.g. 255.122.201.005). With
many Internet Service Providers (ISPs), however, the IP addresses are assigned
dynamically, i.e. the IP addresses of the computers or networks which have access to
the Internet change. There are 3 ways of obtaining a fixed IP address:
Fixed IP address via
dedicated line to
GPRS
The communication partner is connected to the GPRS network
via a leased dedicated line. In this case it has normally been
assigned a fixed IP address by the network operator.
Fixed IP address via
Internet service
provider
The communication partner can be accessed via the Internet and
has been assigned a fixed IP address by the Internet service
provider (the address can be applied for from some Internet
service providers).
Fixed IP address via
DynDNS service To solve the problem of dynamic IP address assignment, DynDNS services can be used. With this kind of service, the
SINAUT MD740-1, for example, or the remote computer,
regardless of the dynamic IP address it currently possesses, is
accessible via a fixed domain name. Each time the IP address
changes, the SINAUT MD740-1 or the remote computer reports
the new IP address to the DynDNS server, so that the current IP
address is always assigned to the domain name on the DNS
server - see glossary, page 95.
The use of a DynDNS service requires a contract with the
provider concerned, e.g. DynDNS.org or DNS4BIZ.com.

If you call up addresses via a domain name (e.g.
www.neuhaus.de), a Domain Name Server (DNS) has to look
up which IP address belongs to the name. You can determine
the following as the Domain Name Server:
•the DNS address of the network operator
OR
•the local IP address of the SINAUT MD740-1, provided that
it is configured to resolve hostnames in IP addresses, see
Services menu.
To determine the Domain Name Server in the TCP/IP
configuration of your network adapter, proceed as described
above.
Proceed as follows:

connection
1. Start a Web browser.
(e.g. MS Internet Explorer from Version 5.0 or Netscape Communicator
from Version 4.0; the Web browser must support SSL (i.e. https))
2. Make sure that the browser does not automatically dial up a
connection when starting.
In MS Internet Explorer you make this setting as follows: menu
Tools, Internet Options..., Connections tab: under Dial-up and
Virtual Private Network settings, Never dial a connection must
be activated.
IP address of the
SINAUT MD740-1:
https://192.168.1.1
3. In the address line of the browser, enter the full address of the
SINAUT MD740-1. In accordance with the default setting, this
is: https://192.168.1.1
Consequence: the security alert shown on the next page
appears.
