Lan-To-Lan Link - DETEWE OpenCom 100 Mounting And Commissioning

If you use the same login name for
the OpenCom 100 user account and
the same password for the network
login, you have to enter this combi-
nation only once when dialling in.
Note: In a larger network with sev-
eral segments, the list of the compu-
ter names visible in the network envi-
ronment can no longer be established
by means of broadcasts. In this case
you use a special WINS server whose
address the OpenCom 100 does not
make known to the workstation
when dialling in. For this reason, you
enter the address of a WINS server

LAN-to-LAN Link

You can use the OpenCom 100 to in-
terlink two LANs via ISDN. To do this
you configure two OpenCom 100
systems in such a way that they can
dial in to each other. In order for this
to work, the two LANs must be con-
figured for different IP address
ranges (sub-networks). For at least
one of the OpenCom 100 systems,
change the prescribed address range
for the LAN.
In the Configurator, NET Configura-
tion: LAN-LAN menu you can con-
figure the dial-in settings. The Open-
Com 100 will set up a connection
whenever a TCP/IP data transfer to
the other LAN is requested.

RAS Access via OpenCom 100 in a LAN
with an IP Server
Please note that such a connection is
only set up when specific requests
are made. These can be for FTP file
transfers, e-mails or downloading
Web pages. A name resolution via
broadcasts is not possible. If you
wish to use the LAN-to-LAN for ac-
cessing files and printers in the Win-
dows network, you need an IP-capa-
ble server that administers the name
resolution for the Windows network.
As the IP address range, you can
select one of the 256 Class C sub-
networks designed for local LANs.
Select a Class C sub-network in the
range from 192.168.0.0 to
192.168.255.0.
