4.                    
5.     NetPeerConfiguration config = new NetPeerConfiguration(gameName);
6.     config.Port = int.Parse(serverParametersArray[1]);
7.     client = new NetClient(config);
8.     client.Start();
9.  
10.     client.Connect(serverParametersArray[0],config.Port);
11.     // and now i need to wait until connection would get approved by server and really work
12.     // if not, then i'l just move on to the next server
