When FastL4 performs hardware acceleration during the TCP handshake, the FastL4 handshake timeout is not updated to match the profile timeout value after the connection is established.
TCP flows in the established state are dropped if they have more than five seconds of inactivity.
Accelerated, established TCP flows with no traffic for more than five seconds.
Disable embedded Packet Velocity Acceleration (ePVA) acceleration.
Once the TCP connection reaches established state, the idle timeout is set to the value found in the associated profile. By default the profile timeout value is 300 seconds.
