6.2.1Dial-up via VPN

For dialing into a network via VPN a workstation requires: an Internet access

a VPN client

LANCOM Systems offers the LANCOM VPN Client on the LANCOM CD. It can be run under Windows 2000 and Windows XP. A detailed description of the LANCOM VPN Client and a description of its installation can also be found on the CD.

For configuring a new profile, select the option 'Configure VPN Remote Access (IPSec over PPTP)' in the LANCOM VPN Client configuration wizard.

The wizard asks then for the values that have been defined during the instal- lation of the RAS access in the LANCOM router.

6.2.2Dial-up via ISDN

A number of settings must be configured on the dial-in computer. These are briefly listed here, based on a Windows computer:

Dial-Up Networking (or another PPP client) must be correctly configured Network protocol (TCP/IP, IPX) installed and bound to the dial-up adapter New connection in Dial-Up Networking with the call number of the router Terminal adapter or ISDN card set to PPPHDLC
