Chapter 6: Providing dial- up access

6 Providing dial-up access

Your LANCOM router supports dial-up 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:

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-up connection in the usual convenient manner.

Security aspects

You must, of course, protect your LAN against unauthorized access. An LANCOM router 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 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.

6.1Which information is required?

The wizard will set up dial-up access for only one user. Please run the wizard again for each additional user.
