Chapter 1: Introduction

Overview

Thank you for purchasing the Linksys BEFCMUH4 Cable Gateway. The
Linksys BEFCMUH4 provides the ideal solution for connecting your wireless
network to a high-speed broadband Internet connection and a 10/100 Fast
Ethernet backbone. Configurable as a DHCP server for your existing network,
the Linksys BEFCMUH4 acts as the only externally recognized Internet
gateway on your local area network (LAN) and serve as an Internet NAT
firewall against unwanted outside intruders. The Linksys BEFCMUH4 can also
be configured to filter internal users' access to the Internet.
A typical gateway relies on a hub or a switch to share its Internet connection,
but the Linksys BEFCMUH4 channels this connection through the blazing, full
duplex of its built-in 10/100 4-Port Switch. This cutting-edge combination of
wireless router and switch technology eliminates the need to buy an additional
hub or switch and extends the range of your wireless network. Now your entire
wireless network can enjoy blazing broadband Internet connections supported
by its robust switched backbone. With the dual-function speed and power of
the Linksys BEFCMUH4, your network will take off at speeds faster than you
ever imagined possible.
