Multiplayer connection issues

[tenchu660]

Hi, I have a weird problem when I try to play with one of my friend.

When He or I make a game, we are not able to connect to each other.
I clic on his game and then the following message appears : connecting...

Nothing else happen. I find it very frustrating since we can't play any skirmish together. The only way we can play together is when somebody else host the game.

Is there anything I can do to fix that problem ? Thanks in advance.
