hello! I have the following network map, and I'm facing new problems with high ping on gaming when both of wans are up and running! Load balance working perfect but each time i try to get on call of duty or any other game my ping goes double! (110+)!! When I'm disconnecting the 4g modem from the load balance then my ping goes down to 60 ms! 

Is there any way to control with er605 what application can use my vdsl etc etc? Or how to calibrate it correct to use my 2nd wan only when my first wan is on full load? 

Thanks in advance
