Unity3d Multiplayer PC and Android

Hey, I'm trying to run my multiplayer on my PC and on my android device and create a match on my PC and connect to the match from my android device.
The problem is that from some reasons that I'm not aware of, I can't find the match in the server list, the reason that I thought was right was port forwarding.. I don't have any ports opened so maybe it's the reason that I can't find the game on my android device..
Anyway, Is there anybody who knows the real reason? and can please tell me how to fix that issue?
Thanks in advance

UPDATE:
I finally did it and make it work.
But now I have another problem
When I'm starting a new match on my PC and then connect to the match from my android device, On my PC I can see both players but on my android device I only see myself..
Which means that the oldest player can see everyone but the newest player can see only himself

Why is that happening? I'm using networkView..
