4 Setting up Internet access

All computers in the LAN can take advantage of the central Internet access of
the LANCOM Router. The connection to the Internet provider can be estab-
lished via the WAN interface which is connected to an ADSL or cable modem.
For models without WAN interface one LAN interface is configurted as DSLoL
interface.

Does the setup wizard know your Internet provider?

A convenient wizard is available to help you set up Internet access. The wizard
knows the access information of major Internet providers and will offer you a
list of providers to choose from. If you find your Internet service provider on
this list, you normally will not have to enter any further transfer parameters to
configure your Internet access. Only the authentication data that are supplied
by your provider are required.

Additional information for unknown Internet providers

If the setup wizard does not know your Internet provider, it will prompt you
for all of the required information step by step. Your provider will supply this
information.

Connection via DSL modem

Protocol: PPPoE

Connection via access router with fixed IP address

Protocol: Plain Ethernet

Additional connection options

You may also enable or disable further options in the wizard, depending on
whether or not they are supported by your Internet provider: 

Time-based billing or flat rate – select the accounting model used by your
Internet provider. 

When using time-based billing, you can set the LANCOM Router to
automatically close existing connections if no data has been trans-
ferred within a specified time (the so-called idle time). 
In addition, you can activate a line monitor that identifies inactive
remote stations faster and therefore can close the connection before
the idle time has elapsed.
