LABEL
#
This is the index number of the firewall log. 128 entries are
available numbered from 0 to 127. Once they are all used, the
log will wrap around and the old logs will be lost.
Time
This is the time the log was recorded in this format. You must
configure menu 24.10 to have the logs display the correct
time.
Packet
This field lists packet information such as: From and To IP
Information
addresses, protocol and port numbers.
Reason
This field states the reason for the log; i.e., was the rule
matched, not matched, or was there an attack. The set and
rule coordinates (<X, Y> where X=1,2; Y=00~10) follow with a
simple explanation. There are two policy sets; set 1 (X = 1) is
for LAN to WAN rules and set 2 (X = 2) for WAN to LAN rules.
Y represents the rule in the set. You can configure up to 10
rules in any set (Y = 01 to 10). Rule number 00 is the default
rule.
This is a log for a DoS attack.
Action
This field displays whether the packet was blocked (i.e.,
silently discarded), forwarded or neither (Block, Forward or
None). "None" means that no action is dictated by this rule.
After viewing the firewall log, enter "y" to clear the log or "n" to retain it. With either option you will be
returned to Menu 21 - Filter and Firewall Setup.
