From

************************
The order of API calls for TCP servers is
* NutTcpCreateSocket()
* NutTcpAccept()
* NutTcpSend(), NutTcpReceive()
* NutTcpCloseSocket()
Note, that this differs slightly from the Berkley API, where the initial
socket is bound to a port and an additional socket is created when a
connection is accepted. Nut/Net doesn't provide a bind call.
*************************
As far as I understand this, once a server socker accepts one incoming
connection you cannot use that socket to listen for more incoming
connections. But I am not an expert here.

I think so, as long as you are able to make the socket visible to the
new thread. However, as I told you before, I think that that socket will
not accept any other incoming connection, no matter what thread you are
using it from.
Please, some guru correct me...

I would use different ports. I ignore other solution here.
