Notes on the different settings:
If you own device features an
ISDN connection
, the Wizard will ask you
whether the remote site also has one.
For VPN connections over the Internet, the type of IP address at each end
must be specified. There are two
types of IP address
. Static and dyna-
mic. The differences between these two IP address types are explained in
the Reference Manual.
The Dynamic VPN function makes it possible to establish VPN connections
between gateways with dynamic IP addresses, and not only between
gateways with static (fixed) IP addresses. An ISDN connection is required
to actively establish VPN connections to remote sites that use dynamic IP
addresses.
If you have not yet given a name to your LANCOM, the Wizard will ask you
to enter a new
name for your device.
Entering a name will cause your
LANCOM to be renamed. Ensure that you give different names to the two
remote devices.
The
name of the remote site
is required for identifying the devices.
In the field
ISDN number
the telephone number of the remote ISDN site
is specified. Enter the full telephone number for the remote site, including
all necessary prefixes (e.g. area codes).
The
ISDN calling line ID
specified is used to identify and authenticate the
caller. If a LANCOM Router is called, it compares the ISDN calling line ID
entered for the remote site to the ID that is actually received over the D
