@zador.blood.stained You are right. Issue was missing reboot after kernel upgrade. Now, it's good. root@orangepizero:~# iptables -nL Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination root@orangepizero:~# uname -a Linux orangepizero 4.14.15-sunxi #28 SMP Mon Jan 29 07:24:48 CET 2018 armv7l armv7l armv7l GNU/Linux Thanks

@Igor First I will go with recompile and test locally. If everything is good, I will contribute in mainline. Thanks.
