I installed parallels in my macbook and I have the game Red Alert 3 installed in windows in the parallels. I can see that i'm connected to the network in windows and the mac and i can access the internet in both. We have 3 computers in the network, two are PC's and one is the macbook. When the PC creates a game in the same network, the other PC can see the game and join it. But the mac, which is connected to the same network, can't see the game and cannot join. How can I fix this network problem?
