Firewall rules are grouped based on the direction of travel of packets to which they
apply. For example, LAN to LAN/Router means packets traveling from a
computer/subnet on the LAN to either another computer/subnet on the LAN
interface of the Prestige or the Prestige itself.
Default Action Use the radio buttons to select whether to Block (silently discard) or Forward
(allow the passage of) packets that are traveling in the selected direction.
Log Select the check box to create a log (when the above action is taken) for packets
that are traveling in the selected direction and do not match any of the rules below.
