http://forum.unity3d.com/threads/matchmaker-issue-working-from-the-same-pc-not-working-from-different-pc.336945/

// This seems to be occasionally required for online matchmaking
// This is your 5-digit project UNET ID at multiplayer.unity3d.com
// This is due to be fixed in an upcoming patch release (was not in 5.1.1p3)
void Awake() {
    PlayerPrefs.SetString( "CloudNetworkingId", "12345" );
}

Snippets

// ClientRpc is called on the server - invokes on clients
[ClientRpc]
public void RpcMyMethod( string msg ) {
	Debug.Log( "Got message from the server: " + msg  );
}

// Commands are called on clients - invokes on the server
// Note that you can only send commands if you own the object it calls from
[Command]
public void CmdMyMethod( string msg ) {
	Debug.Log( "Got message from a client: " + msg );
}

// SyncVars are automatically sent from the server to other clients.
// Note that you still need a command to notify the server of the change
// if it comes from a client. Hook is optional
[SyncVar(hook="OnSomeoneChangedMyString")]
public string myString;
 
public void OnSomeoneChangedMyString( string myString ) {
	this.myString = myString;
	Debug.Log( "Changed myString to " + myString );
}
