DESCRIPTION
The device dropped an ICMP packet that was too large.
The device is saving configuration changes.
DESCRIPTION
Attempted TCP/UDP/IGMP/ESP/GRE/OSPF access
matched the default policy and was blocked or forwarded
according to the default policy's setting.
Attempted TCP/UDP/IGMP/ESP/GRE/OSPF access
matched (or did not match) a configured 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 router sent a message to notify a user that the router
blocked access to a web site that the user requested.
The device blocked a session because the host's
connections exceeded the maximum sessions per host.
A packet from the WAN (TCP or UDP) matched a cone
NAT session and the device forwarded it to the LAN.
DESCRIPTION
The router sent a TCP reset packet when a host was under a SYN
flood attack (the TCP incomplete count is per destination host.)
The router sent a TCP reset packet when the number of TCP
incomplete connections exceeded the user configured threshold.
(the TCP incomplete count is per destination host.)
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.
