Security Configuration
Rev 1 Oct.13 143
Figure 7-10: ACEmanager: Security > MAC Filtering
Packet Inspection
The Packet Inspection group supports two modes of securityNormal (default)
and High Security. A Stateful Packet Inspection (SPI) firewall is a firewall that
tracks the states of network connections and makes decisions on packet
forwarding based on the states defined in the accept or reject policy rules.
Use of an SPI firewall allows for additional device security by implementing
default packet state filtering policies.
Such a firewall typically passes all outgoing packets through, but only allows
incoming packets if they are part of an “Established” connection, ensuring
security. Stateful firewalls are able to track the state of flows in connectionless
protocols (UDP) and connection oriented protocols (TCP).
