The Gateway inspects packets at the application layer, and stores TCP and UDP session
information, including timeouts and number of active sessions. This information Is helpful
when detecting and preventing Denial of Service (DoS) and other network attacks.

Email/Syslog Alert menu to configure your Gateway to send email notifications or add
entries to the syslog when:
!
Traffic is blocked

immediately or at a preconfigured time.
