 +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>
