Accessing the device with WEBconfig
To carry out a configuration with WEBconfig, you need to know how to con-
tact the device. Device behavior and accessibility for configuration via a Web
browser depend on whether the DHCP server and DNS server are active in the
LAN already, and whether these two server processes share the assignment in
the LAN of IP addresses to symbolic names. WEBconfig accesses the LANCOM
either via its IP address, the device name (if configured), or by means of any
name if the device has not yet been configured.
Following power-on, unconfigured LANCOM devices first check whether a
DHCP server is already active in the LAN. Depending on the situation, the
device can either enable its own DHCP server or enable DHCP client mode. In
the second operating mode, the device can retrieve an IP address for itself
from a DHCP server in the LAN.
If a LANCOM Wireless Router or LANCOM Access Point is centrally
managed from a LANCOM WLAN Controller, the DHCP mode is swit-
ched from auto-mode to client mode upon provision of the WLAN
configuration.

Points
In a network without a DHCP server, unconfigured LANCOM devices enable
their own DHCP server service when switched on and assign IP addresses,
information on gateways, etc. to other computers in the LAN (provided they
are set to automatic retrieval of IP addresses – auto DHCP). In this constella-
tion, the device can be accessed by every computer with the auto DHCP func-
tion enabled with a Web browser under IP address
172.23.56.254
.
With the factory settings and an activated DHCP server, the device for-
wards all incoming DNS requests to the internal Web server. This
means that a connection can easily be made to set set up an uncon-
figured LANCOM by entering any name into a Web browser.
