I programmed a server client in java which work, but only with the network of my school. So when i have tried to test it with my home network it didn't work. I have already checked the firewall configuration, but i didn't find any suitable setting to solve my problem. Strangely i can ping my second pc with my main pc, but it doesn't work the other way.
I have already asked this question on stackoverflow, where they said it is network configuration problem.
