1 INTRODUCING THE ROUTER 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. OfficeConnect Cable/DSL Router The OfficeConnect Cable/DSL Router is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several computers. The Router also includes an electronic "firewall" that protects your network using Stateful Packet Inspection (SPI) to detect intruders and prevent them from seeing your files or damaging your computers. The Router can also prevent your users from accessing Web sites which you find unsuitable. This completely equipped, Cable/DSL Router also features Virtual Private Network (VPN) initiation and termination, allowing encrypted links to other private networks. The example in Figure 1 shows a network without a Router where 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.
