LevelOne WBR-6005 - Manual (Page 23)

The Wireless 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 Router and
shows some network topology examples in which the device is
implemented.

The Wireless 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 Router either through a
wired connection to a LAN port, or though the device‘s own wireless
network. The Wireless Router functions as an Internet gateway when set to
Router 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.
