that they are listed.
See Section 11.1 on page 201 for more information about the firewall.

LABEL DESCRIPTION
Firewall Rules
Storage Space
in Use
This bar displays the percentage of the ZyWALL’s firewall rules storage space that
is currently in use. The bar turns from green to red when the maximum is being
approached. When the bar is red, you should consider deleting unnecessary firewall
rules before adding more firewall rules.
Packet Direction Use the drop-down list box to select a direction of travel of packets for which you
want to configure firewall rules.
Note: The VPN connection directions apply to the traffic going to or
from the ZyWALL’s VPN tunnels. They do not apply to other
VPN traffic for which the ZyWALL is not one of the gateways
(VPN pass-through traffic).
Default Policy This field displays the default action and log policy you selected in the Default Rule
screen for the packet direction shown in the field above.
The following read-only fields summarize the rules you have created that apply to traffic traveling in the
selected packet direction. The firewall rules that you configure (summarized below) take priority over
the general firewall action settings above.
# This is your firewall rule number. The ordering of your rules is important as rules are

Address and Service Type drop down lists.
