Example: If Accept Packets from LAN to WAN is enabled and there is a
firewall rule to allow SSH traffic from LAN, then whenever a LAN machine
tries to make an SSH connection, those packets will be accepted and a
message will be logged. (Assuming the log option is set to Allow for the
SSH firewall rule.)
Dropped Packets are packets that were intentionally blocked from being transferred
through the corresponding network segment. This option is useful when the Default
Outbound Policy is ―Allow Always‖.
Example: If Drop Packets from LAN to WAN is enabled and there is a
firewall rule to block ssh traffic from LAN, then whenever a LAN machine
tries to make an ssh connection, those packets will be dropped and a
message will be logged. (Make sure the log option is set to allow for this
firewall rule.)
Enabling accepted packet logging through the firewall may generate a significant
volume of log messages depending on the typical network traffic. This is
recommended for debugging purposes only.
In addition to network segment logging, unicast and multicast traffic can be logged.
Unicast packets have a single destination on the network, whereas broadcast (or
multicast) packets are sent to all possible destinations simultaneously. One other
useful log control is to log packets that are dropped due to configured bandwidth
profiles over a particular interface. This data will indicate to the admin whether the
bandwidth profile has to be modified to account for the desired internet traffic of
LAN users.
