Tcp reset from client fortigate.
This can be solved for managed clients with certificate rollout. But for BYOD devices thats not possible. Yes, this is correct. >>My question: What actually happens if the fortigate does not send the https-replacemsg as suggested by you? If the Fortigate does not seed the https-replacemsg, it will send a TCP RST packet to close the session.

Struggling with 'TCP-RST-from-clt". First of all, I want to apologize for my english. So To put you in image I have a vpn ipsec (configured in Fortigate) with a remote site (one of our clients). I recently start to receive those packets "tcp-rst-from-client" which interrupt the communication with teir applications. If a session timeout and the feature 'set timeout-send-rst enable' is active, the FortiGate sends a 'TCP RST' packet to both sides (client and server). The sequence number within the packet equates the sequence number from the session-table, which is not the correct sequence number for the session. The OS sends an RST packet automatically afterwards. 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.
