[lwip-users] TCP connetion number limit

[R&S_Roberto Chierichetti]

Hi,

I'm using lwIP version 1.4.0 on an AVR32 microcontroller.
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.

Thank you
