Chapter 6: Providing dial- in access
6 Providing dial-in access
Your LANCOM router supports dial-in connections to permit individual com-
puters full access to your network. This service is also known as RAS (Remote
Access Service). In principle, the RAS access can be realized in two different
ways:

A setup wizard handles the configuration of the dial-in connection in the
usual convenient manner.
Security aspects
You must, of course, protect your LAN against unauthorized access. A
LANCOM router therefore offers a whole range of security mechanisms that
can provide an outstanding level of protection:

again for each additional user.

VPN: For a RAS access via VPN, the connection between the LAN and the
dial-in PC is established over a specially secured connection through the
public Internet. The router in the LAN requires VPN support, the dial-in PC
an access to the Internet and the LANCOM VPN Client.
ISDN: For a RAS access via ISDN, a direct connection between the LAN
and the dial-in PC is established over an ISDN dial-up connection. The
router in the LAN requires an ISDN interface, the dial-up PC an ISDN
adapter or an ISDN modem. The data transfer protocol is PPP. Therefore,
the support of all usual devices and operating systems is ensured.
VPN: Network couplings via VPN transmit data by IPSec. The data are
encrypted by AES, 3-DES, Blowfish or CAST encryption algorithms.
ISDN: For network couplings via ISDN, the connection password, the
checking of the ISDN number and the callback function ensure the secu-
rity of the connection.
The ISDN call back function cannot be configured using the wizard. It
can only be set up in the expert configuration. For details, please see
the reference manual.
