Hi, You'll need to increase the number of simultaneous TCP connection MEMP_NUM_TCP_PCB = 4 or more. When the 4th arrives, it WILL begin to be accepted, so you need it.
Then you can discard it.

In my application I need to keep opened up to three TCP connection on the same TCP port. If a 4th connection arrives, while all the other three are already opened, this connection have to be discarded keeping active alle the three existing connections. What happens now on my system is that when the 4th connection arrives, one of the three existing is automatically closed, and the 4th is activated. How I can avoid this ??? I'm currently using BSD socket layer, and I've set MEMP_NUM_TCP_PCB = 3.
