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").
