Firewall rules are grouped based on the direction of travel of packets to which they

apply. For example, LAN to LAN/ZyWALL means packets traveling from a

computer/subnet on the LAN to either another computer/subnet on the LAN interface

of the ZyWALL or the ZyWALL itself.

(discard and send an ICMP destination-unreachable message to the sender) or

Permit (allow the passage of) packets that are traveling in the selected direction.

that are traveling in the selected direction and do not match any of your customized

rules.
