OK, that' working :) I can see server pushed routing configuration and boom! Something not right with ifconfig, see:

ifconfig is symlinked to busybox:

ln -s /bin/busybox /system/xbin/ifconfig
ln -s /bin/busybox /system/xbin/bb/ifconfig
ln -s /system/bin/route /system/xbin/route
ln -s /system/bin/route /system/xbin/bb/route

What now?
