Chapter 3: Basic configuration

New LAN—fully automatic configuration possible

If all connected network devices are still unconfigured, the setup wizard will suggest fully automatic TCP/IP configuration. This may be the case in the fol- lowing situations:

a single PC is connected to the router setup of a new network

Fully automatic TCP/IP configuration will not be available when integrating the LANCOM router in an existing TCP/IP LAN. In this case, continue with the section ’Information required for manual TCP/IP configuration’ →page 29.

The result of the fully automatic TCP/IP configuration: the router will be assigned the IP address '172.23.56.1' (netmask '255.255.255.0'). In addition, the integrated DHCP server will be enabled so that the LANCOM router can automatically assign IP addresses to the devices in the LAN.

Configure manually nevertheless?

The fully automatic TCP/IP configuration is optional. You may also select man- ual configuration instead. Make your selection after the following considera- tions:

Choose 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 conditions is applicable:

You have not yet used IP addresses in your network but would like to do so now. You would like to specify the IP address for your router, selecting it from the address range reserved for private use, e.g. '10.0.0.1' with the netmask '255.255.255.0'. At the same time you will set the address range that the DHCP server uses for the other devices in the network (provided that the DHCP server is switched on). You have previously used IP addresses for the computers in your LAN.

Information required for manual TCP/IP configuration

During manual TCP/IP configuration, the setup wizard will prompt you for the following information:

IP address and netmask for the LANCOM router

Assign a free IP address from the address range of your LAN to the LANCOM router and specify the netmask.
