Run ice in real net

[level]

I test the ice's program .I use call back mode.
the client can call the server's function ,and the server really receive a client's call.but the server could not call the client's function.WhenI run all the program in one computer ,these can run right.
Why?
The program is compiled with ice 2 ,vc2003.
Both computers run in win2003.
