10.4.2 WAN to LAN Rules
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.
See the following figure.

10.5 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 a rule is matched in the Edit Rule screen (see Figure 10-6)
Configure the Log Settings screen to have the ZyWALL send an immediate e-mail message to you
when an event generates an alert. Refer to the chapter on logs for details.
