C#

Hello,
I work at my school, I have a client-server application in C # with Visual Studio 2010 and I have my first client 1 that connects to server. but now I have a problem to connect a server to another client 2 in a VM (Virtual Machine: Virtual Box Windows 7).

Client 2:
* It should be the server connects to the client 2?
* The server sends a message to the client that son located in a virtual machine?
* After sent, the server received a confirmation message from client 2?

So it remains to create of client 2 code that receives a message from the server and client 2 sends a confirmation response to server and client 1?

so when I do the execution console server on my physical machine displays the following address: @ IP: 193.51.91.5:10000 & @ IP: 127.0.0.1:10000
and when I do the execution of the console server in the virtual machine (virtual box with windows 7) displays the following address: @ IP address: 192.168.56.1:10000 & @ IP: 127.0.0.1:10000
Please find attached client / server code.
Very thank you in advance and regards.

thank you
