how to configure (switch ) the network interface to ppp link.
i have been install and setup ppp config.
usb-modeswitch usb-modeswitch-data , ppp pppconfig
and add "4gppp0" interface in /etc/network/interfaces
then add default gw to ppp0.
but it always route to eth0 interface , how to change and configure it ?
