Hi there, I get lots of the errors "Unknown established TCP Packet" in the logs. I know what the message is supposed to mean but what it is supposed to mean does not seem to be occuring in our network. I think I found the cause; If HostA is establishing a connection with HostB it sends the TCP SYN. If HostB does not respond, then HostA retries 3 times. After retrying most hosts just give up. Some hosts/applications however generate a TCP RST and this is what causes the above event. My question is if the above is correct and has anybody else had the same problem ? Is there any fix from checkpoint ? Finally, is the host trying to establish the connection not adhering to the TCP Standards by sending a TCP RST even though it got no response to the TCP SYN ? Any ideas/thoughts would be great.
