Most customers, i talk to, i advice to actually disable the logging of invalid traffic, as this causes more harm than good to see those dropped packets. Why does the application in your case closes the connection? Could be a network issue but likely its a application issue. ![]() ![]() In each case, its not the actual issue at all. So XG does not know the session existed and drops this as well. XG already deleted the session after 3 hours. So he will send to every client a "Please close the connection" packet. After some hours the server "clean up his connection table" and closes all connections left on his table. There are some other reasons, why this can also occur: Cleanup sessions for example: You have a session build up to a Server and did your business. Once Packet Sender’s window show up enter the following information: Name of the packet ASCII text of the message to be send inside the packet IP Address shown by our ESP Port shown by the ESP Select UDP What I have entered is shown below: Now click Send. Every other packet will be dropped, as XG do not have any open connection for this anymore (Stateful firewall). XG will use the first one to delete the session. Some applications are badly written or have other issues so to speak, so they will send multiple "please close this connection" packets. Once connected, a TCP socket can only send and receive. In the same time, XG will delete the connection, because its not needed anymore. You cant send or receive anything until you are connected to another TCP socket on the remote machine. It will forward the packet to the server/client. XG gets a "please close the connection" packet. Afterall those packets will do following: Or it will try to "force the connection to reset" etc. Why does it occur? If you have a open connection (Client to Server) and someone in this connection (Server or Client) closes the connection for what ever reason, the other end will likely "Acknowledge" the closing. In my last 5 years experience, never was this dropped packet an issue - Mainly because its just a symptom for another issue. First of all, this is likely not an issue at all.
