Chapter 3: Basic configuration

After powered on, unconfigured LANCOM devices check first, whether a DHCP server is already active in the LAN. Dependent on the situation, the device is able to switch on its own DHCP server or, alternatively, to activate its DHCP client mode. In this second operating mode, the device itself can obtain an IP address from a DHCP server already existing in the LAN.

Network without DHCP server

In a network without DHCP server, unconfigured LANCOM devices activate their own DHCP server service after starting, and assign appropriate IP addresses and gateway information to the other workstations within the LAN, provided that the workstations are set to obtain their IP address automatically (auto-DHCP). In this constellation, the device can be accessed with any web browser from each PC with activated auto-DHCP function through the name LANCOM or by its IP address 172.23.56.254.

If the configuration PC does not obtain its IP address from the LANCOM DHCP server, figure out the current IP address of this PC (with Start Execute cmd and command ipconfig at the prompt under Windows 2000 or Windows XP, with Start Execute cmd and the command winipcfg at the prompt under Windows Me and Windows 9x, or with the command ifconfig on the console under Linux). In this case, the LANCOM is reachable under the IP address x.x.x.254 ( “x” stands for the first three blocks in the IP address of the configuration PC).

Network with DHCP server

If a DHCP server is active in the LAN to assign IP addresses, an unconfigured LANCOM device will turn off its own DHCP server. It will change into DHCP client mode and will obtain an IP address from the DHCP server of the LAN. This IP address is not known at first. The accessibility of the device depends on the name resolution:

If there is a DNS server for name resolution in the LAN, which inter- changes the assignment of IP addresses to names with the DHCP server,
