I'm not a network expert, so I may be WAY off.Is the windows machine at
146.141.15.10 connected to the same network line as the network cable which
connects to the linux card at 146.141.15.2 ? If not, it might be that
146.141.15.10 is looking for 146.141.15.2 on the same network. Try switching the
two IP's around and see if you can ping the second card. If it works, you might
have to use a 192.168.0.x IP, or use a direct connection to the other network
line. Another possibility would be to change the netmask of the machine at
146.141.15.10, to not include 146.141.15.2 as being on the same line.
