Thank you so much Zoltan Lajos Kis for your great help and suggestion. I did it using OFPP_IN_PORT. But I have only one problem when working with OpenWrt on TP Link 1043. When controller is not connected clients still communicate with each other via wlan. Don't know what is the problem posted this problem many times but nobody responded to this conversation. Can you help me in this regard?
