Packet
Information
This field lists packet information such as: From and To IP
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.
not match
<1,01> dest IP

does not match the
destination IP address in

reasons (instead of dest
IP) are src IP, dest port,
src port and protocol.

silently discarded), forwarded or neither (Block, Forward or
