It will work if you refuse multiple connections from *different* IP
addresses. In the accept handler if the ip address is the same as the first
accepted connection, allow it, otherwise refuse it. I believe this is what
you really want to do - refuse connections from different IP addresses, yes?
Below acceptedPcb is the first pcb accepted and is set to NULL when the last
connection closes.
static struct pcb *acceptedPcb;
static err_t accept(void *arg, struct tcp_pcb *pcb, err_t err)
{
if(acceptedPcb != NULL && acceptedPcb->remote_ip.addr !=
pcb->remote_ip.addr)
{
tcp_close( pcb );
return ERR_OK;
}
