[Wine] rFactor dedicated problem

[JuanPollo]

RFactor I have installed the game on a Linux distribution (Ubuntu 8.04), and I can open items in perfectly with the executable "Dedicated.exe rFactor. I have no apparent problems, from any machine can access the item that appears in the play list.
The problem arises when I connect to the game directly via IP address, then the game can not find the game and for him there. Some library problem "Wine? Does anyone know how to solve this?
Thank you very much.
