Exceed MAX incomplete,
sent TCP RST
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”.
Access block, sent TCP
RST
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").
