135 Chapter 11 Firewall Configuration
The default rule for WAN to LAN traffic blocks all incoming connections (WAN to LAN). If
you wish to allow certain WAN users to have access to your LAN, you will need to create
custom rules to allow it.
11.4.2 Alerts
Alerts are reports on events, such as attacks, that you may want to know about right away. You
can choose to generate an alert when an attack is detected in the Edit Rule screen (select the
Send Alert Message to Administrator When Matched check box) or when a rule is matched
in the Edit Rule screen.
When an event generates an alert, a message can be immediately sent
to an e-mail account that you specify in the Log Settings screen (see the chapter on logs).
