Overview

Congratulations on the purchase of your new Internet Gateway.
The Internet Gateway will allow multiple SOHO (Small Office Home Office) users to share Internet user accounts. It provides a low-cost method of giving users of your network access to the vast resources available on the Internet. Once the Internet Gateway is installed and configured, the Internet is just a click away.

The Internet Gateway is able to use your modem(s) to connect to your ISP (Internet Service Provider), providing the required log-in information.
You can seamlessly connect to the Internet as if you had a permanent connection.

Alternatively, you can use the Internet Gateway to provide a seamless, automatic connection to another LAN, provided a matching device is installed on the other LAN.

Firewall Protection

The firewall protection provided by the Internet Gateway is an intrinsic side effect of IP sharing. All users on the LAN share a single external IP address. From the external viewpoint, there is no network, only a single device.

For internal users, the Internet Gateway acts as a "transparent proxy server", translating the multiple internal IP addresses into a single external IP address.

For external requests, any attempt to connect to local resources are blocked. The Internet Gateway will not "reverse translate" from a global IP address to a local IP address.

This type of "natural" firewall provides an impregnable barrier against malicious attacks.
