Packets have a source and a destination. The packet direction matrix in the lower part of the
screen sets what the ZyWALL does with packets traveling in a specific direction that do not
match any of the firewall rules.
To set the ZyWALL to by default silently block traffic from the WAN from going to the DMZ
interfaces, you would find where the From WAN row and the To DMZ column intersect and
set the field to Drop as shown.
Figure 125 Default Block Traffic From WAN to DMZ Example
11.3 Packet Direction Examples
Firewall rules are grouped based on the direction of travel of packets to which they apply. This
section gives some examples of why you might configure firewall rules for specific
connection directions.
