Providing dial-in access 7-1
7 Providing dial-in access
Your SwyxConnect supports dial-in connections to permit individual
computers 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:
• 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.
A setup wizard handles the configuration of the dial-in connection in
the usual convenient manner.
7.0.0.1 Security aspects
You must, of course, protect your LAN against unauthorized access.
A SwyxConnect therefore offers a whole range of security
mechanisms that can provide an outstanding level of protection:
• 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 security 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.
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.
