7.4.1 LAN To WAN Rules
The default rule for LAN to WAN traffic is that all users on the LAN are allowed non-
restricted access to the WAN. When you configure a LAN to WAN rule, you in essence want
to limit some or all users from accessing certain services on the WAN. See the following
figure.
Figure 35 LAN to WAN Traffic
7.4.2 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.
Figure 36 WAN to LAN Traffic
7.5 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 39
on page 110 ) . 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.
