Hello, I'd like to get an automatic wake on LAN, which means that the router itself wake up asleep clients when a service is required from them.
Then, I need to modified some package to get this point. I need some help with which package should I modified, maybe "iptables", or maybe "bridge-utils". I don't really know.

Which package should I study in order to understand the code and be able to modified it. The ideal one would be that package where all the frames are filtered.
