Chapter 1.Introduction OfficeConnect VPN Firewall User’s Manual

1 Introduction

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.

This User Manual will show you how to set up the OfficeConnect Gigabit VPN

Firewall, and how to customize its configuration to get the most out of this

product.

1.1 OfficeConnect Gigabit VPN Firewall

The OfficeConnect Gigabit VPN Firewall is designed to provide a robust, secure

solution for multi-site small businesses. This completely equipped, broadband-

capable Virtual Private Network (VPN) firewall prevents unauthorised external

access to your network — and by creating Virtual Private Networks (VPNs) —

encrypted links to other private networks. The OfficeConnect Gigabit VPN

Firewall also provides Denial of Service (DoS) protection and intrusion detection

using Stateful Packet Inspection (SPI), web content filtering, logging and

reporting.

1.2 System Requirements

In order to use the OfficeConnect Gigabit VPN Firewall for Internet access, you

must have the following:

 ADSL or cable modem and the corresponding service up and running, with

at least one public Internet address assigned to your WAN

 One or more computers each containing an Ethernet 10Base-T/100Base-

T/1000Base-T network interface card (NIC)

 (Optional) An Ethernet switch, if you are connecting the device to more

than four computers on an Ethernet network.

 For system configuration using the supplied web-based program: a web

browser such as Internet Explorer v5.5 or later.
