No state update from client (Network)

Hello, I have small network connection script, which starts server and connects other player to it. In my scene I have cube with NetworkView component attached. So my problem is, when I start server and other player connects, the cube sends state update only from server. What I mean is when I move cube as server it moves on both server and client windows, but when I move it as client it moves only on client's window. What could cause that? By the way, if client spawns that cube, then cube sends state update to server as it should.

Here's my script:

 private var refreshing:boolean;
 private var hostData:HostData[];
 
 private var btnX:float;
 private var btnY:float;
 private var btnW:float;
 private var btnH:float;
 var gameName:String = "MP_Project";
 var Helicopter:GameObject;
 function Start()
 {
     btnX = Screen.width * 0.05;
     btnY = Screen.height * 0.05;
     btnW = Screen.width * 0.1;
     btnH = Screen.width * 0.05;
 }
 
 function startServer()
 {
     Network.InitializeServer(32, 25001, !Network.HavePublicAdress);
     MasterServer.RegisterHost(gameName, "MP_Project", "The MP");
 }
 function refreshHostList()
 {
     MasterServer.RequestHostList(gameName);
     refreshing = true; 
 }
 
 function Update()
 {
     if(refreshing)
     {
         if(MasterServer.PollHostList().Length > 0)
         {
             refreshing = false;
             Debug.Log(MasterServer.PollHostList().Length);
             hostData = MasterServer.PollHostList();
         }
     }
 }
 
 function OnServerInitialized()
 {
     Debug.Log("Server initialized");
 }
 

 
 function OnMasterServerEvent(mse:MasterServerEvent)
 {
     if(mse == MasterServerEvent.RegistrationSucceeded)
     {
         Debug.Log("Registered");
     }
 }
 
 function OnGUI()
 {
     if(!Network.isClient && !Network.isServer)
     {
         if(GUI.Button(Rect(btnX, btnY, btnW, btnH), "Start Server"))
         {
             startServer();
         }
         if(GUI.Button(Rect(btnX, btnY*1.2 + btnH, btnW, btnH), "Refresh Hosts"))
         {
             refreshHostList();
         }
         if(hostData){
             for (var i:int = 0; i<hostData.length; i++)
             {
                 if(GUI.Button(Rect(btnX*2+btnW, btnY*1.2 + (btnH * i), btnW * 3, btnH*0.5), hostData[i].gameName))
                 {
                     Network.Connect(hostData[i]);
                 }
             }
         }
     }
 }
