+  * seems to work with 4.14, Test: https://github.com/frank-w/BPI-R2-4.14/tree/4.14-hnat [[http://forum.banana-pi.org/t/bpi-r2-kernel-4-14-hnat/4486/43|forum]]

+Current implementation works only between lan and wan (not wifi or other interfaces)
+at least you have to setup nat on wan:
+<code>
+ipt=/sbin/iptables
+if_wan=wan
+${ipt} -t nat -F
+${ipt} -t nat -A POSTROUTING -o ${if_wan} -j MASQUERADE
+</code>
+and load hnat-module:
+  modprobe mtkhnat
+Check if it is working with
+<code>
+#via debugfs (working shows BIND-state)
+cat /sys/kernel/debug/hnat/all_entry
+#via interrupts (counter does not increase after a while (download))
+cat /proc/interrupts | grep 'ethernet'
+</code>
