[lwip-users] TCP connetions number limit

[address@hidden]

Hi,
 
I'm using lwIP version 1.4.0 on an AVR32 microcontroller.
In my application I need to keep opened up to three TCPconnection on the same 
TCP port.
If a 4th connection arrives, while all the other three arealready opened,  
this connection have tobe discarded keeping active alle the three existing 
connections.
 
What happens now on my system is that when the 4thconnection arrives, one of 
the three existing is automatically closed, and the4th is activated.
 
How I can avoid this ???
 
I'm currently using BSD socket layer, and I've setMEMP_NUM_TCP_PCB = 3.
 
Thank you
