8.4.3 RAS Access
In a LAN with an IP-enabled server you can also enable external computers to dial in via the OpenCom 100. To do this, you should coordinate with the network administrator the IP address space which can be assigned to an external computer dialling in, and enter it in the Configurator, Network: RAS: ISDN menu, under
Address Range.

RAS access by the OpenCom 100 in a LAN with an IP server
The user account administered by the OpenCom 100, with which dialling in is permitted, only allows the establishment of direct and anonymous TCP/IP connections such as HTTP, FTP or SMTP connections. If you additionally want to allow file or printer access in the network, you must set up a suitable user account on the addressed server for network log-in. If you use the same log-in name for the
OpenCom 100 user account and the same password for the network log-in, you have to enter this combination only once when dialling in.
Note: In a larger Windows network with several segments, the lists of computer names visible in the network environment can no longer be established by broadcasts. In this case you use a special WINS server whose address the
OpenCom 100 does not make known to the workstation computer when dialling in with ISDN. For this reason, you enter the address of a WINS server manually in the network settings of the workstation.
