The Wireless Broadband Router is designed to be very flexible in its
deployment options. It can be used as an Internet gateway for a small
network, or as an access point to extend an existing wired network to
support wireless users. It also supports use as a wireless bridge to connect
up to four wired LANs.
This chapter explains some of the basic features of the Wireless Broadband
Router and shows some network topology examples in which the device is
implemented.

The Wireless Broadband Router can connect directly to a cable or DSL
modem to provide an Internet connection for multiple users through a
single service provider account. Users connect to the Wireless Broadband
Router either through a wired connection to a LAN port, or though the
device's own wireless network. The Wireless Broadband Router functions as
an Internet gateway when set to Gateway Mode.
An Internet gateway employs several functions that essentially create two
separate Internet Protocol (IP) subnetworks; a private internal network
with wired and wireless users, and a public external network that connects
to the Internet. Network traffic is forwarded, or routed, between the two
subnetworks.
