LANCOM 821+ – LANCOM 1711+ VPN – LANCOM 1721 VPN

Chapter 6: Providing dial- in access

Networking first. When connected, they can search for and access
computers in the remote network (via

Find

Computer

s, not

through the Network Neighbourhood).

6.2

Settings for the dial- in computer

6.2.1

Dial- up via VPN

For dialing into a network via VPN a workstation requires:

an Internet access

a VPN client

LANCOM Systems offers a 30 days trial version of the LANCOM Advanced VPN
Client on the LANCOM CD. A detailed description of the LANCOM Advanced
VPN Client and a description of its installation can also be found on the CD.

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

6.2.2

Dial- 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

PPP selected as the Dial-Up server type, 'Enable software compression'
and 'Require data encryption' unchecked

Select desired network protocols (TCP/IP, IPX)

Additional TCP/IP settings:

Assignment of IP address and name server address enabled

'IP header compression' disabled

These settings will permit a PC to dial into a remote LAN via ISDN and access
its resources in the usual manner.

6.3

Instructions for LANconfig

Launch the 'Provide Dial-In access (RAS)' wizard. Follow the wizard's
instructions and enter the required information.
