DESCRIPTION
This is the direction of travel of packets (LAN to Router, LAN to WAN, WAN to
Router, WAN to LAN).
Firewall rules are grouped based on the direction of travel of packets to which they
apply. For example, LAN to Router means packets traveling from a computer/
subnet on the LAN to the ZyXEL Device itself.
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.
