Welcome to the world of networking with 3Com ® . In the modern
business environment, communication and sharing information is crucial.
Computer networks have proved to be one of the fastest modes of
communication but, until recently, only large businesses could afford the
networking advantage.

Firewall Router The OfficeConnect ADSL Wireless11g Firewall Router is designed to
provide a cost-effective means of sharing a single broadband Internet
connection amongst several wired and wireless computers. The Router
also provides protection in the form of an electronic “firewall” preventing
anyone outside of your network from seeing your files or damaging your
computers. The Router can also prevent your users from accessing Web
sites which you find unsuitable.
Figure 1 shows an example network without a Router. In this network,
only one computer is connected to the Internet. This computer must
always be powered on for the other computers on the network to access
the Internet.
