problem with re-building TCP/IP connection on Nios

Hi Cris, thank you for your reply :)

I have tried your advice, and it almost solve my problem. The PC which previously established with the old ip address still couldn't connect to the Nios (even though I have cleared the Nios' old ip address from PC's ARP table and waited for several minutes). But when I try to connect from another PC (from different ip address of course), I can connect to the Nios (Horray!! :) ).

So is there a mechanism 'client-list' in Nios (sorry, I don't know how to call it) that stores any ip address which ever connected to the Nios? If there is, how to clear that 'list'? :confused: Or maybe you notice another problem in this case.

Looking forward your reply, Thanks!
