Email Notifications of Event Logs and Alerts
The firewall logs can be configured to log and then email denial of access, general attack
information, and other information to a specified email address. For example, your VPN firewall
will log security-related events such as: accepted and dropped packets on different segments of
your LAN; denied incoming and outgoing service requests; hacker probes and login attempts; and
other general information based on the settings that you enter on the Firewall Logs & E-mail
screen. In addition, if you have set up content filtering on the Block Sites screen (see “Blocking
Internet Sites (Content Filtering)” on page 4-30), a log will be generated when someone on your
network tries to access a blocked site.
To configure email or syslog notification, or to view the logs, see “Activating Notification of
Events and Alerts” on page 6-23.
