DESCRIPTION
The router sent a TCP reset packet when a TCP
connection state was out of order.Note: The firewall refers
to RFC793 Figure 6 to check the TCP state.
The router sent a TCP reset packet when a dynamic
firewall session timed out.
The default timeout values are as follows:
ICMP idle timeout: 3 minutes
UDP idle timeout: 3 minutes
TCP connection (three way handshaking) timeout: 270
seconds
TCP FIN-wait timeout: 2 MSL (Maximum Segment
Lifetime set in the TCP header).
TCP idle (established) timeout (s): 150 minutes
TCP reset timeout: 10 seconds
The router sent a TCP reset packet when the number of
incomplete connections (TCP and UDP) exceeded the
user-configured threshold. (Incomplete count is for all
TCP and UDP connections through the firewall.)Note:
When the number of incomplete connections (TCP + UDP)
> "Maximum Incomplete High", the router sends TCP RST
packets for TCP connections and destroys TOS (firewall
dynamic sessions) until incomplete connections <
"Maximum Incomplete Low".
The router sends a TCP RST packet and generates this log
if you turn on the firewall TCP reset mechanism (via CI
command: "sys firewall tcprst").
DESCRIPTION
Attempted access matched a configured filter rule
(denoted by its set and rule number) and was blocked
or forwarded according to the rule.
