DESCRIPTION
This is the direction of travel of packets. Select from which zone the
packets come and to which zone they go.
Firewall rules are grouped based on the direction of travel of packets to
which they apply. For example, from LAN to LAN means packets
traveling from a computer or subnet on the LAN to either another
computer or subnet on the LAN.

Zone.

The entry with a hyphen (-) instead of a number is the default firewall
behavior that the ZyWALL performs on traffic that does not match any
other traffic direction. Only the access right and log alert are configurable
for the default firewall rule. To apply other behavior, configure a firewall
rule that traffic will match so the ZyWALL will not have to use its default
behavior.
This is the position of your firewall rule in the global rule list (including all
through-ZyWALL and to-ZyWALL rules). The ordering of your rules is
important as rules are applied in sequence. Default displays for the
default firewall behavior that the ZyWALL performs on traffic that does
not match any other traffic direction. The ZyWALL checks the traffic
against any other applicable rules before applying this default behavior.
This field tells you the schedule object that the rule uses. none means
the rule is active at all times if enabled.
