Object: I am trying to establish socket connection between computers in the LAN
using TCP/IP, these computers belong to different domain and in different IP band.

Problem: If two computer are in same IP band, such as 192.168.1.xxx, they can be
connected. But if they are in different IP band, such as 192.168.0.xxx and 192.168.1.xxx,
connection can't be established.

If you know how to solve the problem, please reply here or send email to [email protected]
Thanks in advance.
