Chapter 3: Basic configuration
Section ’TCP/IP settings to workstation PCs’ auf Seite 41 will describe the settings required for the individual workstations in the LAN.
3.3Instructions for WEBconfig
To configure the router with WEBconfig you must know how to address it in the LAN. The reaction of the devices, as well as their accessibility for configu- ration via web browser is dependent on whether a DHCP server and a DNS server are already active in the LAN, and whether these two server processes exchange the assignment of IP addresses to symbolic names within the LAN between each other.
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
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
