LANCOM 821 ADSL/ISDN – LANCOM 1621 ADSL/ISDN – LANCOM 1711 VPN

 Chapter 3: Basic configuration

34

EN

Enable DHCP server?

Disable the DHCP server function in the LANCOM if you would like to have
a different DHCP server assign the IP addresses in your LAN.

3.1.2

Configuration protection

The password for configuration access to the LANCOM protects the configu-
ration against unauthorized access. The configuration of the router contains
a considerable amount of sensitive information such as your Internet access
information. We therefore strongly recommend protecting it with a password. 

The setup wizard for the basic configuration automatically disables remote
configuration access via ISDN, thus protecting your configuration against
tampering. ISDN remote configuration access can be enabled at any time
using the security wizard (see “Have you permitted remote configuration?” on
page 69).

3.1.3

Settings for the DSL connection

For the WAN connection it may be necessary to enter the transfer protocol
being used. The wizard will e.g. automatically enter the correct settings for
major DSL providers. You only need to enter the protocol used by your access
provider if the wizard does not list your provider. 

3.1.4

Settings for the ISDN connection

Set up the basic configuration of your ISDN connection if required. You will
need the following data:

One or more ISDN MSNs on which the router will accept calls. MSNs are
ISDN subscriber numbers that are assigned to you by your telephone pro-
vider. They are normally entered without an area code. These numbers are
only relevant for the router functions (LAN to LAN coupling, RAS), not for
remote configuration and LANCOM VPN Option.

A dialing prefix for access to the public telephone network. This is nor-
mally required only when using an ISDN PBX. '0' is the usual prefix. It is
used for all outgoing calls. 

Finally, you should know whether your telephone provider transmits an
ISDN connect-charge pulse. This signal can be used LANCOM for con-
nect-charge budgets and the accounting function.
