What is the

SuperStack 3

Firewall?

The SuperStack

3 Firewall is a dedicated firewall appliance which is

installed between a Private LAN and a Router. The Firewall is a complete

network security system with all hardware and software pre-installed.

This allows it to act as a secure gateway for all data passing between the

Internet and the LAN.

The purpose of the Firewall is to allow a private Local Area Network (LAN)

to be securely connected to the Internet. You can use the Firewall to:

■

Prevent theft, destruction, and modification of data.

■

Filter incoming data for unsafe or objectionable content.

■

Log events which may be important to the security of your network.

The Firewall has three Ethernet ports which are used to divide the

network into separate areas.

■

The Wide Area Network (WAN) port attaches to the Internet access

device, for example, Router or Cable Modem.

■

The Local Area Network (LAN) port attaches to the local network

through hubs and switches. LAN users have access to Internet services

such as e-mail, FTP, and the World Wide Web. However, all

workstations and data on the LAN are protected from hacker attacks

that might come through the WAN port.
