Packet Direction
AMG1312-T10D User's Guide
DESCRIPTION
This is the direction of travel of packets (WAN to LAN, LAN to WAN, WAN to Router,
LAN to Router).
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 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.
Click this to save your changes.
Click this to restore your previously saved settings.
DESCRIPTION
This read-only bar shows how much of the Device's memory for recording firewall
rules it is currently using. When you are using 80% or less of the storage space, the
bar is green. When the amount of space used is over 80%, the bar is red.
Use the drop-down list box to select a direction of travel of packets for which you
want to configure firewall rules.
