LABEL DESCRIPTION
Active Firewall Select this check box to activate the firewall. The P-79X performs access control
and protects against Denial of Service (DoS) attacks when the firewall is
activated.
Packet Direction This is the direction of travel of packets (LAN to LAN / Router, LAN to WAN,
WAN to WAN / Router, WAN to LAN).
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 P-79X or the P-79X itself.
Default Action Use the drop-down list boxes to select the default action that the firewall is to
take on packets that are traveling in the selected direction and do not match any
of the firewall rules.
Select Drop to silently discard the packets without sending a TCP reset packet or
an ICMP destination-unreachable message to the sender.
Select Reject to deny the packets and send a TCP reset packet (for a TCP
packet) or an ICMP destination-unreachable message (for a UDP packet) to the
sender.
Select Permit to allow the passage of the packets.
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 your
customized rules.
