OfficeConnect Cable/DSL Secure Gateway

INTRODUCING THE OFFICECONNECT CABLE/DSL SECURE GATEWAY

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. The OfficeConnect® product range from 3Com has changed all this, bringing networks to the small office.

The products that compose the OfficeConnect line give you, the small office user, the same power, flexibility, and protection that has been available only to large corporations. Now, you can network the computers in your office, connect them all to a single Internet outlet, and harness the combined power of all of your computers.

OfficeConnect Cable/DSL Secure Gateway

The OfficeConnect Cable/DSL Secure Gateway is designed to provide a cost-effective means of sharing a single broadband Internet connection amongst several computers.

The Gateway also increases your network security by acting as a firewall — preventing unauthorised external access to your network — and by creating Virtual Private Networks (VPNs) — encrypted links to other private networks.

The example in Figure 1 shows a network connected to the Internet without a Gateway. One computer is connected to the Internet using a Cable or DSL modem. This computer must always be powered on for the other computers on the network to access the Internet.

When you use the Cable/DSL Secure Gateway in your network (Figure 2), it becomes your connection to the Internet. Connections can be made directly to the Gateway, or through an OfficeConnect Hub or Switch, expanding the number of computers you can have in your network.
