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 VoIP Router
Setting up a new network
Fully automatic TCP/IP configuration will not be offered if you are integrating
the LANCOM VoIP 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
VoIP 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 VoIP Router can assign the devices in the LAN IP addresses auto-
matically.
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 the manual TCP/IP configuration if you are familiar with networking
and IP addresses, and you would like to specify the IP address for the
router yourself (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 activated).
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.
Server: The LANCOM VoIP Router operates as DHCP server in the net-
work; as a minimum its own IP address and the network mask must
be assigned.
