Session Timeouts Default
Session can be idle and open for certain time before it times out. This setting is a for non-TCP/UDP traffic set at default of 30 sec. The default value is good in this case as it is insecure for opening for longer time when the protocol is not well known or established. If the traffic is internal software or application and it is needing more time than the default timeout, then time can be customized through creating a custom app and setting a timeout.
