    I've made some progress: I purge ufw and iptables, then install iptables first then change to iptables-legacy. after that install ufw. ufw seems to works only on iptables-legacy. apt purge ufw iptables apt install iptables update-alternatives --set iptables /usr/sbin/iptables-legacy update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy apt install ufw now: root@linaro-alip:~# ufw allow ssh ERROR: initcaps [Errno 2] modprobe: FATAL: Module ip6_tables not found in directory /lib/modules/4.4.194 ip6tables v1.8.2 (legacy): can't initialize ip6tables table `filter': Table does not exist (do you need to insmod?) Perhaps ip6tables or your kernel needs to be upgraded. Maybe ip6tables are missing in kernel? root@linaro-alip:~# sudo modprobe ip6_tables modprobe: FATAL: Module ip6_tables not found in directory /lib/modules/4.4.194 root@linaro-alip:~# ^C root@linaro-alip:~# sudo modprobe ip6tables modprobe: FATAL: Module ip6tables not found in directory /lib/modules/4.4.194
