I want to Write extra Performance in inet-->bulktransfer and the central server (zserver) built by my network send and receive any messages

[Roger]

Hi dear Helpers, I have two problems: First, i want to write in my network that each computer sends performance data to the server and the server forwards the values to the central server. Please how can i implement it in inet-->bulktransfer? Second, i've built my own network of "inet -> bulktransfer. But the problem is: the central server (zserver) built by my network send and receive any messages. What have i done wrong please? Below You can see my ned file and my ini file. I also send them as attachments to this e-mail. Thank you very much in advance for your help.
