I can't find multiplayer matches to join!! What? Nobody is hosting a game?

[yurikal]

I never find a multiplayer match to join.
Unfortunately I can't host because I am not behind a UPnP NAT,
but I don't understand if there is nobody playing online multiplayer or if I have some problem also when I have to search for a game hosted by someone else, and I can't see the "real" list of the games available ??
If somebody can just tell me if it is normal because nobody is playing multiplayer or maybe it's my problem ?
Thank you.
Bye
