How do Nios-II handle IP address change during the TCP/IP connection?

Dear all, I have problem with changing IP address in the FPGA board. Here is my case, let say I have a FPGA board which is connected to PC. The PC sends a command to the FPGA that asks th...

Hi, I want to ask you some questions.

You said that after you changed the Nios' IP address, you didn't need to close the previous connection or re-initialize the TCP/IP connection. When your Nios changed its IP address, was it still connected to any client or not :confused:? I mean, has The Nios accepted a TCP/IP connection request from any client before it changed its IP address?

In my case, before the Nios changed its IP address, it was still connected to a client. And my problem is in maintaining or rebuilding a new TCP/IP connection to the same client.

Would you share a piece of your code? I'm still curious how you can maintain the TCP/IP connection despite of Nios IP changes. If you mind to put it in this public thread, you may send it by private message to me.

Thank you.

p.s. I really appreciate if there are anyone have suggestion to solve my problem. :(
