Figure 267: M7i Router CFEB with ASP-I
The ASP–I is an optional component of the CFEB. The ASP–I is similar to the standalone
Adaptive Services PIC, but operates at a reduced bandwidth. The ASP–I enables you to
perform one or more services on the same PIC by configuring a set of services and
applications.
The ASP–I provides the following services:
•
Stateful firewall—A type of firewall filter that considers state information derived from
previous communications and other applications when evaluating traffic.
•
Network Address Translation (NAT)—A security procedure for concealing host
addresses on a private network behind a pool of public addresses.
•
Intrusion detection services (IDS)—A set of tools for detecting, redirecting, and
preventing certain kinds of network attack and intrusion.
The configuration for these three services comprises a series of rules that you can arrange
in order of precedence as a rule set. Each rule follows the structure of a firewall filter,
with a from statement containing input or match conditions and a then statement
containing actions to be taken if the match conditions are met. For information about
