1. Introduction
This manual describes the configuration procedures performed after installing the B-
FOCuS 270/285/400PR router. The manual is intended for use by skilled technicians
with a solid background in telecommunications.
The B-FOCuS router enables the connection of computers interconnected by a local
area network (LAN) to the Wide Area Network (WAN) via an ADSL dial-up
network.
The FOCuS 270PR router has one Ethernet port. It can be connected to one computer
or to up to 128 computers, by means of an Ethernet hub. The Ethernet port rate can be
either 10 or100Mbps.
The FOCuS 285PR router resembles the FOCuS 270PR router, but has an additional
USB link (so you can connect it to two computers).The FOCuS 400PR router has an
internal Ethernet hub with four ports. It can connect up to four computers to a
common ADSL line. The Ethernet ports rates can be either 10 or100Mbps.
The router can be installed either as a bridge (in layer 2 of the Communication model)
or as a router (in layer 3 of the Communication model). It contains an internal dialer,
as well as additional services, such as Dynamic Host Configuration Protocol (DHCP),
Network Address Translation (NAT) and Firewall. The configuration software is
burned into a flash memory. You can modify it to your needs according to the type of
local network, the type of telephony infrastructure and the agreements you made with
the suppliers of telephony and Internet services.
The following figure describes a typical connection of the B-FOCuS 400PR router to
the LAN and the WAN. The router routes the traffic among these networks.
By definition, the IP address of each new router at the eth0 port at the LAN side is
192.168.1.1 and the subnet mask is 255.255.255.0. These definitions can be modified
as part of the configuration.
This manual describes all the configuration user interface features. It also presents
typical workflows of using the configuration definition interface.
