Note: The following modem sharing options are available, but N-Tron does not provide technical
support for using third party software with the 102RAS (N-Tron also does not provide any
software for this use).
If you are using your 102RAS for dial-out, you will have to select one of the Modem Sharing options and
select the Country Code. With any of the Modem Sharing options, the TCP port number used to access the
modem is 7000. Modem Sharing with authentication means a login prompt will be issued to the socket
when it is opened. The opener of the socket must provide appropriate credentials before access is given to
the modem. If RAW is also selected – support for RFC 2217 (com port control vial Telnet) will be disabled.
Modem Sharing – No Authentication - Immediate access is given to the modem.
Modem Sharing – Local Authentication - A valid set of credentials, defined in the Local User data base,
is required before access is granted.
Modem Sharing – Radius Authentication - A valid set of credentials, defined in the Radius User data
base, is required before access is granted.
Modem Sharing – Raw Mode with No Authentication - User data is treated “as is”, without
interpretation, and no authentication is required.
Modem Sharing – Raw Mode with Local Authentication - User data is treated “as is”, without
interpretation, and a valid set of credentials, defined in the Local User data base, is required before access is
granted.
Modem Sharing – Raw Mode with Radius Authentication - User data is treated “as is”, without
interpretation, and a set of credentials, defined in the Radius User data base, is required before access is
granted.
Caution: Modem sharing is accomplished by implementing a Telnet interface to the 102RAS’s embedded
modem. Secure the access to the port via a firewall or IP filter settings to prevent unauthorized use of your
modem resource.
Authentication
This page shows the current Authentication configuration of the 102RAS.
Authentication Setup
Remote Host Address
Radius Server Address 1 and Port
Radius Accounting Address 1 and Port
Secret
If your database for user credentials resides in the Local User Database on the 102RAS, then accept the
default – “local”. If your user database resides on a Radius Server, then click on the down arrow and choose
radius.
If modem usage is RAS, enter a static IP Address in the Remote Host Address window which will be
assigned to the dial-in user. This Remote Host Address has to match the network scheme of the 102RAS.
