7 Providing dial-up access
Your LANCOM Office supports dial-up connections to permit individual com-
puters full access to your network. This service is also known as RAS ( R emote
A ccess S ervice).
The physical connection is realized via ISDN. An ISDN adapter or ISDN
modem is therefore the only hardware requirement for the PC. PPP is used as
the data transfer protocol. This ensures that all common devices and operat-
ing systems are supported.
A setup wizard handles the configuration of the dial-up connection in the
usual convenient manner.
Security aspects
You must, of course, protect your LAN against unauthorized access. A LAN-
COM Office therefore offers a whole range of security mechanisms that can
provide an outstanding level of protection:
•
Password-protected connections - simple and effective security.
•
Verification of the ISDN subscriber number - for increased security.
•
Callback function - the highest security levels can be achieved by setting
the router to call participants back at a number specified earlier.
The callback function cannot be configured using the wizard. It can only be
set up in the expert configuration. For details, please see the LANCOM refer-
ence manual.
7.1 Which information is required?
The wizard will set up dial-up access for only one user. Please run the wizard
again for each additional user.
User name and password
Users authenticate themselves with this information when dialing in.
Incoming number
The LANCOM Office uses the optional ISDN caller ID as an additional user
authentication. This security function should not be used when users dial in
from differing locations.
