how to mark pptp or other type of vpn UPLOAD and DOWNLOAD seperately to use it later on in queues?
considering that there is also queues for WAN interface in place.
I know that to mark upload traffic you choose ether1(wan) as upload interface and to mark download traffic you choose ether2(lan) interface as download interface.
how can i apply this on the VPN interface, it is only one interface.
thanks
