DESCRIPTION
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.
Table 53 on page
653.
DESCRIPTION
ICMP access matched the default policy and was blocked
or forwarded according to the user's setting.
ICMP access matched (or didn't match) a firewall rule
(denoted by its number) and was blocked or forwarded
according to the rule.
The firewall allowed a triangle route session to pass
through.
The router blocked a packet that didn't have a
corresponding NAT table entry.
The firewall does not support this kind of ICMP packets or
the ICMP packets are out of order.
The router sent an ICMP reply packet to the sender.
