ip_nat_pptp stretch not work

Hi. I have debian box with nat as gateway. With debbian jessie pptp from local network worked, with loaded kernel module ip_nat_pptp. After upgrade to debian stretch - pptp not working any more, module ip_nat_pptp loaded. Anyone have similar working configuration? # Generated by iptables-save v1.6
