General information

The following entries are required to set up a RAS connection. The first column
indicates whether the information is required for a VPN (standard method
using “preshared keys“) and/or an ISDN connection.

Further details to network couplings via VPN using enhanced methods
(e.g. digital certificates) can be found in the LCOS reference manual.  

Notes to the individual values:

User name and password

:

 

Users authenticate themselves with this

information when dialling in. 

Incoming number

: The LANCOM Router uses the optional ISDN caller ID

as an additional user authentication. This security function should not be
used when users dial in from differing locations.
