14.4.3 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 (see

Section 14.6.1 on page 176

).

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).

This is the direction of travel of packets (LAN to LAN/Router, LAN to WAN, WAN

to WAN/Router or WAN to LAN.
Firewall rules are grouped based on the direction of travel of packets to which they

apply. For example, LAN to LAN/Router means packets traveling from a

computer/subnet on the LAN to either another computer/subnet on the LAN

interface of the Prestige or the Prestige itself.
