4.2 Security

This section describes the AT-iMG models built-in security facilities, and how to configure and monitor them.

4.2.1 Overview

The aim of this chapter is to teach you how to configure security services to manage and restrict the traffic that

passes between the Internet and your network, and protect your network infrastructure from attacks. The

components of the package are:

• Network Address Translation (NAT) component; maps multiple addresses on a private network to an exter-

nally-visible address (or range of addresses) on the outside network

• Firewall component; blocks certain traffic between interfaces based on stateful packet information (SPI)

Option Description Default Value

name An existing route. To display route names, use the IP

LIST ROUTES command.

N/A

number An existing route. To display route numbers, use the

IP LIST ROUTES command. The number appears in

the first column under the heading ID.
