New LAN – fully automatic configuration possible
The setup wizard offers to configure TCP/IP fully automatically if no network
devices connected have yet been configured. This usually happens in the fol-
lowing situations:
Only a single PC is going to be attached to the LANCOM VPN Router
Setting up a new network
Fully automatic TCP/IP configuration will not be offered if you are integrating
the LANCOM VPN Router into an existing TCP/IP LAN. In this case please con-
tinue with the section 'Required information for manual TCP/IP configuration'.
The result of fully automatic TCP/IP configuration is as follows: The LANCOM
VPN Router is assigned the IP address '172.23.56.254' (network mask
'255.255.255.0'). The integrated DHCP server is also activated so that the
LANCOM VPN Router can assign the devices in the LAN IP addresses automat-
ically.
Should you still configure manually?
Fully automatic TCP/IP configuration is optional. Instead of this you can select
manual configuration. Make this selection after considering the following:
Select automatic configuration if you are
not
familiar with networks and
IP addresses.
Select manual TCP/IP configuration if you are familiar with networks and
IP addresses and one of the following statements is true:
You have not yet used any IP addresses in your network but would like
to now; You would like to specify the IP address for the router yourself
and would like to assign it a user-defined address from one of the
address ranges reserved for private use, for example '10.0.0.1' with
a network mask of '255.255.255.0'. If you do this you simultaneously
specify the address range that the DHCP server will subsequently use
for the other devices in the network (provided the DHCP server is acti-
vated).
You have so far also used IP addresses on the computers in the LAN.
Required information for manual TCP/IP configuration
When performing manual TCP/IP configuration the Setup Wwizard prompts
you for the following information:
DHCP mode of operation
Off: The IP addresses required must be entered manually.
