This TCP RST packet also ends the session, so the end reason is set to tcp-rst-from-client. As long as the download was ok, everything is fine. The reason for this abrupt close of the TCP connection is because of efficiency in the OS. A TCP RST (reset) is an immediate close of a TCP connection. The FortiGate unit sends a reset to the client and drops the firewall session from the firewall session table. This is used for TCP connections only. If set for non-TCP connection based attacks, the action will behave as Clear Session. If the Reset Client action is triggered before the TCP connection is fully established, it acts as Clear Session.Want to learn how to reset a circuit breaker?
